Radiology & Imaging
At Indiana University Health Paoli Hospital, our radiologists use advanced imaging technologies to diagnose many conditions. The physicians at IU Health Paoli Hospital have advanced education in reading these images to make proper diagnoses. We provide safe care using the lowest doses of radiation possible for the most accurate results.
Using the latest technology, we are able to view soft tissue, brain waves, blood vessels and the musculoskeletal system without invasive treatment. Our radiology and imaging services staff is glad to answer any of your questions about imaging techniques, including how to prepare for your imaging test.

In addition to traditional X-rays, our diagnostic imaging techniques include ultrasound, digital mammography, computed tomography (CT) scans, nuclear medicine, magnetic resonance imaging (MRI) and bone densitometry.
- CT scans. CT scans use a single X-ray machine to take pictures from many different angles. A computer then puts the images together into a three-dimensional (3D) image of the body. CT scans offer physicians a larger amount of information than X-rays. During certain exams, a contrast dye may be used to make blood flow or certain organs easier to see.
- Digital mammography. Mammography is a low-dose X-ray study of the breast. It is designed to identify breast cancer early in its development, even when it is too small to feel. A screening mammogram is done in women who have no signs of breast cancer, and typically involves two X-rays of each breast to help discover tumors that cannot be felt.
- MRI. This imaging technique uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed, digital images of the body. MRIs offer more advanced imaging than X-rays, ultrasounds or CT scans, giving physicians a better way to look at the body and diagnose conditions.
- Bone density scan. Bone density scanning, also called dual-energy X-ray absorptiometry (DEXA), or bone densitometry, uses low radiation X-rays to determine bone mineral density. The test is typically performed on the hip or lower spine. It is noninvasive and only takes five to 10 minutes.
- Ultrasound. Ultrasound imaging involves exposing part of the body to high-frequency sound waves to produce pictures of the inside of the body. Ultrasound exams do not use radiation. Because ultrasound images are captured in real-time, they can show the structure and movement of the body’s internal organs and blood flowing through the blood vessels. Conventional ultrasounds display the images in thin, flat sections of the body. Advancements in ultrasound technology include 3D ultrasounds that format the sound wave into 3D images. Four-dimenstional (4D) ultrasounds are 3D ultrasounds in motion.
- Nuclear medicine imaging. Nuclear medicine imaging uses low-level radioactive isotopes to help physicians determine organ size, shape and function. You may receive the isotopes through a liquid to drink or an injection. A special camera can then take images of the isotopes as they move through the body and into organs. The amount of radiation is typically less than a conventional X-ray or CT scan. Nuclear medicine imaging is most often used when the function of an organ is important to diagnosis, not simply the shape or size of the organ.
