Body Imaging encompasses the use of multiple modalities, specifically CT and MRI, to image the bony and soft tissues of the anatomy.
CT (Computed Tomography)
Also sometimes called a CAT scan, CT is a safe and painless exam that uses x-ray technology to obtain detailed, cross-sectional images of a patient’s body.
CT is often the preferred technology for diagnosing cancer and for visualizing several types of tissue with great clarity, including organs such as the liver, spleen, pancreas and kidneys.
Cross-sectional images are obtained by CT when a quietly rotating gantry emits a small amount of x-ray that passes through a patient’s body. The result is a thin image or “slice” that is reconstructed on a computer along with other slices to view the anatomy.

MRI (Magnetic Resonance Imaging)
MRI is safe, painless and potentially one of the most accurate, noninvasive procedures available to obtain images of the body. In many cases, a high quality MRI reveals exquisite anatomic detail and eliminates the need for additional diagnostic procedures. In MRI, a magnet is used in conjunction with radio waves and a sophisticated computer system to generate accurate images of the body without using any radiation. MRI is frequently used to study muscles, joints, the brain and spine, the abdomen, pelvis, chest and blood vessels.
MRA (Magnetic Resonance Angiography)
Magnetic Resonance Angiography (MRA) is a specific type of MRI scan that is optimized to show blood vessels and blood flow. Physicians use this test to rule out blood vessel disorders and plan treatment. MR angiography is used to examine blood vessels in key areas of the body, including the brain, kidneys, pelvis, legs, lungs, heart, neck, abdomen.
MRA is commonly used to identify disease and aneurysms in the aorta, both in the chest and abdomen, in the brain or in other major blood vessels. It is also used to detect and evaluate the severity of atherosclerotic disease – which is a narrowing of the blood vessels and limits blood flow – in the carotid artery of the neck, which may lead to stroke, the coronary ateries, and the arteries of the legs. MRA also identifies dissection or splitting in the aorta in the chest or abdomen or its major branches and examines pulmonary arteries in the lungs to detect pulmonary embolism, which may be caused by blood clots from leg veins, as well as to aid in surgical preparation.
Common MRI Studies include:
- Vascular (MRA)
- Venous (MRV)
