Radiology (X-ray)
An image is made by radiation in the form of X-rays passing through the body. The image is recorded digitally and stored in PACS (Picture Archiving and Communication System). The Radiologist interprets the images and dictates a report that is sent to your physician. If your physician practices locally he/she is able to view your images on his/her computer in the office. Typically X-rays are taken to help diagnose disease and diagnose broken bones. Xrays are often used to help guide the Radiologist during procedures such as biopsies, arthrograms and angiograms.

Read our Frequently Asked Questions –
Nuclear Medicine Accreditation

DEXA is a enhanced form of X-ray that is used to measure bone loss—osteoporosis. Usually the lower spine and hips are X-rayed with a dedicated machine and then a computer measures the amount of bone loss.

CT (CAT Scan)   ACR Accredited
CT Scans are X-ray beams that rotate through narrow sections of the body. Many scans are taken in a short time and produces multiple images. A computer reconstructs the scans to produce two dimensional images.

Typical CT scans are done of the head, chest, abdomen and pelvis. Some times the test involves drinking barium and also getting an IV contrast. These are used to get a better image.

Nuclear Medicine
Nuclear Medicine tests use small amounts of radioactive material to visualize the structure and function of organs, tissue, bones or systems of the body.

Typical nuclear medicine tests include: lungs, gall bladder, thyroid and heart.

Ultrasound / Echocardiography
Ultrasound uses high frequency sound waves to produce images. Doppler ultrasound may be used during the test. Doppler ultrasound is a technique that evaluates blood flow through a blood vessel.

Typical ultrasound exams include: abdomen, gall bladder, breast, pregnancies, kidneys, arteries and veins.

The heart can also be examined using ultrasound. Many times a Stress test is done in connection with Ultrasound.
