Radiology & Imaging
Advanced imaging aids diagnosis and treatment
Modern imaging gives doctors ways to see inside the body for accurate diagnosis and treatment.
Doctors rely on radiology and imaging—and on the radiologists who read these images—for diagnosis of many conditions. Indiana University Health Radiology & Imaging uses several types of imaging to help diagnose and treat various conditions accurately. Some imaging technologies, such as computed tomography (CT) scans and positron emission tomography (PET) scans use radiation to make pictures of the inside of your body. Magnetic resonance imaging (MRI) and ultrasound are examples of imaging that does not use radiation.
Our radiologists also perform treatment procedures using imaging technology. This is a special discipline called interventional radiology. Our interventional radiologists perform delicate procedures inside your body using imaging equipment to guide instruments very accurately.
Services we provide include:
- Bone densitometry
- Complete breast imaging
- Computed tomography imaging services (CT scan)
- Diagnostic radiology
- Interventional radiology
- Magnetic resonance imaging (MRI)
- Nuclear medicine
- Positron emission tomography (PET) scans
- Varicose vein ablation and treatment
Learn about imaging technologies used at IU Health Radiology & Imaging
Modern imaging technologies can be intimidating. Many use large machines, radiation, special fluids to drink or have injected—or a combination of all of these. Understanding the process of imaging can make you more comfortable with your imaging procedure. Here is some brief information about four common imaging technologies.
X-rays are pictures made by exposing part of your body to very weak radiation that exposes a film or special plate (called a phosphor plate). X-rays are painless, and new technology that employs reusable phosphor plates exposes you to even less radiation than was used in the past.
Magnetic resonance imaging (MRI) uses a very strong magnet and pulses of radio waves to take pictures of the inside of your body. The MRI machine is very large and makes loud noises, but these noises are part of the machine’s normal operation. Sometimes you may have to drink or have injected a special liquid, called a contrast agent, to highlight some part of your body in the MRI images.
A computed tomography (CT) scan combines X-ray images taken from many different angles. A computer processes these images to produce 3-D images of the inside of your body. Sometimes a contrast agent is used for a CT scan. Because this technology uses many X-ray images, you are exposed to a higher level of radiation than with a standard X-ray. Nevertheless, CT scans are considered safe and are a very effective diagnostic tool.
A mammogram uses X-rays to take a picture of the inside of your breast. To take this picture, your breast is gently compressed between two plates for less than thirty seconds. During a mammogram, your radiation exposure is very low, less than for most standard X-rays.
We’re building the future
IU Health Radiology & Imaging offers residencies and fellowships to train the next generation of radiologists. Our partnership with Indiana University School of Medicine puts us on the forefront of research to create newer, more accurate imaging technologies to aid diagnosis and treatment of many kinds of disorders.
