Radiology
Radiology uses various forms of imaging to diagnose, monitor and treat conditions within a patient’s body. By obtaining detailed images of internal structures, providers can obtain a report from a radiologist to assist in making an accurate diagnosis. Medical imaging plays a vital role in early detection, diagnosis and treatment planning in every healthcare service line.
Some imaging techniques serve as real-time guides for treatment procedures. The specialty of interventional radiology, for example, uses these precision images to combine diagnosis with treatment in a single procedure that’s often less invasive than traditional surgery.
Radiology services are essential to modern healthcare and play a critical role in improving patient outcomes. Medical Imaging supports accurate diagnosis and personalized treatment plans, and helps providers deliver high-quality, safe care. At UCHealth, radiology services remain at the forefront of medical innovation, helping to ensure effective, efficient and patient-centered care.
Radiology services offered
Radiologists are physicians who specialize in interpreting medical images. They complete extensive medical training to accurately read imaging studies and provide detailed reports to your ordering provider. Interventional radiologists also perform image-guided procedures.
Technologists and sonographers are highly trained professionals who perform imaging exams and guide patients through the process. Depending on the exam ordered, they use X-ray, CT, MRI, fluoroscopy, ultrasound or nuclear medicine equipment to create high-quality images for diagnosis and treatment.
Radiology includes many types of imaging, each designed for specific clinical needs.
Radiology vs imaging
Is there a difference between radiology and imaging? This is a common question. The answer is yes, but the terms are different and are also closely related.
Radiology refers to the type of medicine practiced by radiologists. These physicians are specially trained to read medical images and use them to diagnose conditions. Radiology refers to clinical decision-making based on imaging. Radiologists read scanned images and create reports for ordering providers. The specialty also includes interventional radiologists. Interventional radiologists perform procedures using CT, MRI, US or X-ray imaging as a guide. Some of those procedures include:
- Placing stents
- Draining abscesses
- Performing biopsies
- Treating tumors
Imaging is the process of obtaining images, which radiologists read. Imaging studies are typically performed by trained radiologic technologists or sonographers, using specialized equipment to guide patients through the process of taking the images needed for the treatment process.
Imaging refers to the technology and scanning processes used to create images of the inside of a patient’s body. Imaging consists of the following modalities:
- X-rays
- CT scans
- MRI
- Ultrasound
- Mammography
- Nuclear medicine
Imaging and Radiology at UCHealth work together and are vital in the care of our patients.
Magnetic Resonance Imaging (MRI)
MRI is magnetic resonance imaging, an imaging technique that uses a powerful magnetic field and radiofrequency to generate images. Images are generated with slices, which create detailed images of the human body. Specialized MRI radiologists can distinguish various types of tissue used to diagnose and treat conditions. This imaging is non-invasive and provides a detailed view of the human body. MRI-trained technologists guide patients through the process of obtaining the necessary imaging for our radiologists to read.
There are various types of MRI scans, including, but not limited to:
- Functional MRI (fMRI)
- Brain MRI
- Cardiac MRI
- Breast MRI
- Upper and lower
- Spinal MRI

Safety
MRI magnetic resonance imaging does not use radiation that can be seen as harmful to patients. Contrast may be given in some exams to enhance the visualization of blood flow and tissue changes. Many MRI exams use contrast, which is administered orally or intravenously, to highlight blood vessels and organs. Contrast is safe and generally does not cause a reaction or side effects. MRI patients are rigorously screened for safety. UCHealth maintains strict conditions in our MRI departments to provide the highest level of care. Patients are screened at the time of scheduling for metal implants and allergies. Patients who have implants may require additional screening before scheduling. Some of the implants that may need additional screening are:
- Pacemakers
- Stimulators
- Implantable cardioverter- defibrillators
- Loop recorders
- Insulin pumps
- Cochlear implants
- Deep brain stimulators
At check-in, the technologist performs another safety screening to make sure we provide the highest level of care. Before your imaging, all patients are asked to change into scrubs as an added safety measure. MRI exams require patients to remain very still. Radiology technologists ensure patients are positioned correctly for optimal images.
Results
Imaging results are sent to your ordering provider. Patients can also review their results in the UCHealth MHC app. The availability of results may vary depending on the type of imaging performed. Please contact your provider with any questions regarding your imaging results. MRI is a powerful, non-invasive tool that provides diagnostic accuracy without radiation exposure. MRI is vital in disease treatment and monitoring.
Nuclear Medicine and PET/CT
Nuclear Medicine and PET/CT are radiological diagnostic imaging tests that use small amounts of radioactive materials called tracers to evaluate organ function and detect disease processes. After the tracer is administered, a specialized camera detects the radiation it emits as it travels through your body, and a computer processes this information to create detailed images of your organs and tissues. The amount of radiation used in nuclear medicine is relatively low, and your physician will carefully weigh the benefits of the exam against any potential risks when recommending it.
These scans are commonly used to diagnose conditions such as:
- Alzheimer’s disease
- Heart disease
- Thyroid disorders
- Bone abnormalities
- Kidney dysfunction
- Cancer
- Gallbladder dysfunction
- Liver dysfunction
- Congenital abnormalities
Some of the scans offered in this modality include:
- PET/CT scans
- Bone whole body scans
- Thyroid scans
- Cardiac stress tests
- DaTscan
- Gastric emptying
- HIDA scans (hepatobiliary iminodiacetic acid scan)
In addition, the Nuclear Medicine department at UCHealth offers theranostic cancer treatments. This involves treating tumor cells using the following radionuclides:
- Lutathera
- Pluvicto
- Xofigo
- I-131
PET (Positron Emission Tomography), CT, and SPECT (Single Photon Emission Computed Tomography) utilize the same radiological process as nuclear medicine, combining CT technology to provide both functional and anatomical information in a single high-resolution 3D-image. This powerful scan improves diagnostic accuracy for disease progression and helps in treatment planning.
Our specialized radiologists and nuclear medicine physicians can interpret these scans by analyzing the distribution and patterns of the tracer. UCHealth follows strict safety protocols and keeps radiation exposure as low as possible while providing high-quality imaging.
During the scheduling process, patients are given information to prepare for their imaging appointments. Imaging check-in times and duration vary based on the exam and protocol. This information is provided during scheduling and can also be found in the MHC application.
Imaging results are sent to your ordering provider. Patients can also review their results in the UCHealth MHC app. The availability of results may vary depending on the type of imaging performed. Please contact your provider with any questions regarding your imaging results.
Nuclear medicine at UCHealth is cutting-edge imaging that provides information that cannot be found using any other imaging modality. This makes nuclear medicine imaging essential for diagnosis and treatment plans.
Diagnostic Radiology (General X-ray and Fluoroscopy)
Diagnostic radiology is the foundation of medical imaging and one of the most widely used specialties within radiology. Diagnostic X-ray and fluoroscopy use a small amount of radiation to create images of the body. Generally, X-ray imaging is the first step in diagnosing injuries and illnesses. Plain film X-rays are fast and effective for examining bones, lungs and the abdomen.
Fluoroscopy provides moving imaging, which allows our radiologists to observe body systems, providing diagnosis and treatment. GI (gastrointestinal studies) imaging (such as barium swallows or enemas), joint injections, catheter placements and swallowing studies are commonly performed.
There is an additional list of exams that are performed in our diagnostic X-ray departments:
- Barium X-rays – Fluoroscopy allows the radiologist to see any abnormalities in the GI tract. We can imagine the movements of the barium that is administered via mouth or rectum.
- Arthrography – This imaging, which uses X-rays to see a joint or joints.
- Placement of IV (intravenous) – During this imaging, a catheter is inserted, and fluoroscopy is used to place the catheter into a vessel inside the body.
- Hysterosalpingogram – Imaging of the uterus and fallopian tubes.
- Retrograde urethrogram or micturating cystourethrogram – These images can identify abnormalities of the urinary system.
Our diagnostic radiologists are trained to interpret these images. They use them to find abnormalities, and the reports are sent to your ordering provider to help build your care plan. UCHealth’s dialogistic radiology technologist will guide you safely through the scanning process, creating images of your body using equipment based on your providers’ orders.
Imaging results are sent to your ordering provider. Patients can also review their results in the UCHealth MyHC app. The availability of results may vary depending on the type of imaging performed. Please contact your provider with any questions regarding your imaging results.
Computed Tomography (CT)
Computed Tomography (CT) scans use X-ray photons (ionizing radiation) to create detailed cross-sectional images of the body, offering more information than a standard X-ray. CT imaging is a fast, painless, and non-invasive way to diagnose and treat patients. The CT scanner moves in a circular motion, taking images from the needed angles. Our computer processes the scans by creating 3D-images for our radiologist to use in order to diagnose various conditions. Your ordering provider will use this information to create a treatment plan if needed.
Contrast dyes may be used to highlight areas of the body, including but not limited to organs or blood vessels. Contrast is safe.
What to expect during your imaging:
Upon your arrival, a technologist or tech assistant will take you back to the CT scan room. They will have you remove all metal or jewelry from the neck up (i.e., hearing aids, cochlear implants, glasses, earrings, hairpins and removable dental work). You will be asked to lie on the CT table on your back, and the technologist will position you in the machine and begin the exam. You will move in and out of the machine several times. The
technologist will give you instructions on when the injection begins. It’s very important to remain still for the duration of the exam. The exam normally takes 5-10 minutes.
CT imaging offered includes, but is not limited to:
- Brain
- Head/Neck
- Cardiac
- Abdomen/Pelvis
- IVP
- Enterography
- Cystogram
- Spine
If you will need contrast for your imaging, an IV will be started within the imaging department. You may experience a warm flushing sensation, a metallic taste in your mouth, slight nausea and the sensation of a full bladder. This is normal and will subside after the injection. We encourage patients to drink water for the rest of the day.
Results
Imaging results are sent to your ordering provider. Patients can also review their results in the UCHealth MyHC app. The availability of results may vary depending on the type of imaging performed. Please contact your provider with any questions regarding your imaging results.
Digital Mammography
Digital Mammography (2D and 3D) uses a small, safe amount of ionizing radiation to image the breasts. Specialty-trained radiologists view these images, making comparisons year to year, looking for changes in the breast tissue that may signify normal breast changes or potentially cancer.
Screening mammography is recommended annually for women aged 40 and over, for the early detection of breast cancer, and for patients with no breast concerns. Diagnostic mammography is used to evaluate specific concerns such as lumps, pain or abnormal screening results.
Additional breast imaging services may include:
- Breast ultrasound
- Breast MRI
- CEM (contrast-enhanced mammography)
- ABUS (automated breast ultrasound)
- Image-guided biopsies
- Lesion localization
Breast imaging radiologists have specialized training in detecting subtle findings and distinguishing between benign and suspicious changes. Early detection through mammography significantly improves treatment outcomes and survival rates.
Breast imaging technologists are specially trained to position patients carefully to ensure high-quality images. Advances such as 3D tomosynthesis, contrast-enhanced mammography and ABUS have improved cancer detection rates for all patients, particularly in women with dense breast tissue.
During the scheduling process, patients are given information to prepare for their imaging appointments. Imaging check-in times and duration vary based on the exam and protocol. This information is provided during scheduling and can also be found in the MHC application.
Imaging results are provided to your ordering provider. Patients may review their results in the UCHealth MHC app. If results are not seen in the app after 3 days, a letter will be sent in the mail. The availability of results may vary depending on the type of imaging performed. Please contact your provider with any questions regarding your imaging results.
Breast imaging services are a critical component of preventive care and comprehensive health services.
Interventional Radiology (IR)
IR (Interventional Radiology) is a radiology modality that is used along with radiology technologists, nurses and radiologists. IR uses advanced imaging technology—such as X-ray, ultrasound, CT and MRI—to perform minimally invasive, image-guided procedures.
IR procedures are performed through small incisions using catheters, needles and wires guided by X-ray, CT, ultrasound or MRI. These procedures often replace or significantly reduce the need for traditional open surgery.
Common interventional radiology procedures include:
- Biopsies
- Abscess drainage
- Angioplasty
- Stent placement
- Embolization to control bleeding or treat tumors
- Placement of feeding tubes
- Dialysis access placement
These procedures often result in reduced pain, fewer complications and faster recovery times compared to surgery.
Interventional radiologists are physicians trained in both imaging interpretation and procedural techniques. They work closely with referring providers to offer alternative treatment options for complex conditions.
Interventional radiology represents a growing area of medicine that blends diagnostic imaging with therapeutic care, expanding the role of radiology from diagnosis to direct patient treatment.
Imaging results are provided to your ordering provider. Patients can also review their results in the UCHealth MyHC app. The availability of results may vary depending on the type of imaging performed. Please contact your provider with any questions regarding your imaging results.
