Medical imaging services

We offer a variety of diagnostic imaging modalities to patients in Richmond, Midlothian and the surrounding area. Our expert staff of board-certified radiologists and technologists work closely with physicians to get patients on their way to diagnosis, treatment and good health.

Computed tomography (CT scan)

A CT scan, also called a computerized axial tomography (CAT) scan, uses X-rays to generate detailed images of the body. CT scans may be used to detect broken bones, cancers, blood clots, signs of heart disease and internal bleeding. We offer several types of CT scanning, including positron emission tomography (PET scan).

Diagnostic radiology

Diagnostic radiology involves a variety of diagnostic and image-guided therapeutic techniques, including all aspects of radiological diagnosis. It is usually one of the first tools primary care providers use to diagnose medical conditions.

Electrocardiogram (ECG or EKG)

An electrocardiogram, commonly referred to as an ECG or EKG, measures the electrical activity of your heart by putting small electrical sensors on your skin. An EKG can help your doctor diagnose heart problems, such as heart attacks or arrhythmias.

Electroencephalogram (EEG)

An electroencephalogram (EEG) evaluates brain activity. This study is painless and helps your doctor assess brain function affected by certain conditions and diseases, such as trauma, coma, infection, brain cancer and dementia.

Magnetic resonance imaging (MRI)

Magnetic resonance imaging (MRI) uses magnetic fields instead of radiation to create images of the organs and structures within the body. It allows your healthcare provider to get a better look than he or she would with other imaging techniques. MRI helps diagnose a wide range of conditions and helps optimize surgical outcomes.

Interventional radiology

Interventional radiology uses X-rays, MRIs and other imaging techniques to insert a catheter into an artery, sometimes to treat a heart attack caused by a blockage. Interventional radiology treatments offer less risk, less pain and a faster recovery time than open surgery.


We offer a wide range of breast imaging services, including mammography. Mammography uses low-dose X-rays to create images of your breast tissue. Mammograms are used as a screening tool for breast cancer in patients without symptoms, as well as a diagnostic tool to confirm the presence of breast cancer in patients with symptoms. Mammography can detect a breast abnormality before you can feel it by hand.

Nuclear imaging

Nuclear imaging procedures use small amounts of radioactive material to pinpoint molecular activity within the body. Nuclear medicine may be used to diagnose heart disease, stress fractures, gastrointestinal conditions, bone abnormalities, cancers, neurological disorders and other diseases.


Ultrasounds use high-frequency sound waves to create video images of soft tissue areas of the body, including the reproductive, cardiovascular and gastrointestinal organs , and is often used during pregnancy.
