Imaging Procedures and Tests

We offer the following imaging procedures at our three locations. Visit our locations page to find out which procedures are offered at a specific location.


At Johnston Medical Center-Smithfield and Johnston Medical Center-Clayton, we want to make your mammogram as comfortable as possible. That’s why we have the latest innovations in women’s health care – Senographe Essential full-field digital mammography system from GE Healthcare. Senographe Essential produces digital images on a computer screen, which help our doctors make accurate diagnoses. With this technology, you’ll experience short exam times, fast results and fewer callbacks – all resulting in less anxiety and superior care. Plus, Senographe Essential is designed with you in mind, making your exam more comfortable than ever before.

A screening mammogram is an x-ray of the breast used to detect breast changes in women who have no signs or symptoms of breast cancer. It usually involves two x-rays of each breast. Mammograms make it possible to detect tumors that cannot be felt. Mammograms can also find tiny deposits of calcium in the breasts that sometimes indicate the presence of breast cancer.

A diagnostic digital mammogram is an X-ray of the breast that is used to check for breast cancer after a lump or other symptom has been found. A diagnostic mammogram also may be used to evaluate changes found during a screening mammogram. A diagnostic mammogram takes longer than a screening mammogram because it involves more X-rays in order to obtain views of the breast from several angles.

Magnetic Resonance Imaging (MRI)

An MRI is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. MRI also may be done to provide more information about a problem seen on an X-ray, ultrasound scan, or CT scan. Contrast material may be used during MRI to show abnormal tissue more clearly.

Computed Tomography (CT)

CT is a diagnostic procedure that uses special x-ray equipment to obtain cross-sectional pictures of your body. The CT computer displays your pictures as detailed images of organs, bones and other tissues.


Fluoroscopy is performed to make it possible to see your internal organs in motion or other body parts with real-time images displayed on a video monitor.


An ultrasound test uses high-frequency sound waves to produce dynamic visual images of your organs, tissues or blood flow. The sound waves are transmitted to the area of interest and the returning echoes recorded. This type of procedure is often referred to as a sonogram or ultrasound scan.

Bone Density Testing

Our technologists measure the bone density in your spine, hips and wrists, which are the most common sites of fractures due to osteoporosis.

Diagnostic X-Ray

An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. An x-ray machine produces a small burst of radiation that passes through the body, recording an image on photographic film or a special detector. X-rays are the oldest and most frequently used form of medical imaging. Diagnostic Contrast Procedures use a special form of x-ray called fluoroscopy and a contrast material called barium to provide the medical images needed for your doctor to diagnose your condition.

Nuclear Medicine

In nuclear medicine imaging, radiopharmaceuticals are taken by a patient, orally or through an IV, and localize on a specific organ or cellular receptor. These radiopharmaceuticals emit radiation from within the body, which is captured in images by external detectors. This allows doctors to study the physiology of a specific organ or tissue, which helps some diseases be detected at an earlier stage than other diagnostic tests would allow.

Interventional Radiology

This minimally invasive image-guided procedure is used to detect and treat diseases in almost every organ in the body. Interventional radiologists use CT Scans, MRI, ultrasounds, and other imaging methods to obtain images of the organs, which are then used to guide instruments through the body. This method can be used to treat many conditions that once required surgery, and can reduce risk for patients and improve health outcomes.
