Diagnostic Imaging

Our Diagnostic Imaging Department provides vital diagnostic images to the physician and care team. These complex and extremely detailed images are essential in helping physicians and providers identify a patient’s injury or illness. The greater the detail, the more accurate the diagnosis. The Diagnostic Imaging Department is available to patients 24 hours a day, every day.

Board Certified Physicians and licensed, certified staff provide services using advanced diagnostic technology from the finest imaging manufacturers in the world. Service is provided in a relaxed, comfortable setting. Patients and family members will be treated with respect, dignity and kindness.

The Equipment and Diagnostic Imaging available at Rockcastle Regional includes:

Computed Tomography (CT Scan)

Rockcastle Regional’s Siemens Somatom Sensation 64 Slice CT scanner is fast enough to actually capture a heartbeat and perform multiple cardiac exams at once. This CT can visualize the smallest arteries in the heart and can be used instead of heart catheterizations.

Computed tomography (CT) scanning blends the traditional use of X-rays with the latest computer innovations. CT imaging uses special x-ray equipment to produce cross-sectional images or pictures of the inside of the body and a computer reconstructs these slices to produce a 3D image of the areas being studied. When the image slices are reassembled by computer software, the result is a very detailed multidimensional view of the body’s interior. CT scans of internal organs, bone, soft tissue and blood vessels provide greater clarity than conventional x-ray exams.

A CT scan is a quick and painless procedure. It allows the technologist to acquire images in just a few seconds while you lay on the patient table.

CT imaging can also play a significant role in the detection, diagnosis and treatment of vascular disorders that can lead to stroke, gangrene or kidney failure.


Ultrasound, or sonography, involves using high-frequency sound waves to produce pictures of the inside of the body. Ultrasound images are captured in real-time and show the structure and movement of the body’s internal organs, as well as blood flowing through blood vessels. This procedure is used to examine internal organs such as the heart and blood vessels, liver, gall bladder, pancreas, kidneys, bladder, uterus, ovaries, thyroid and fetus in pregnant patients. Ultrasound is helpful in diagnosing a variety of conditions.


X-ray is simply a procedure used to evaluate injury to the extremities: arms, legs, hands and feet. This type of imaging is frequently used to diagnose fractures or broken bones. Rockcastle Regional’s General Electric units provide the most advanced technology available.

Densitometry (Bone Density Scan)

A bone density scan determines whether you have osteoporosis or are at risk of osteoporosis. Osteoporosis is a disease that causes bones to become more fragile and more likely to break.

In the past, osteoporosis could only be detected after you broke a bone. By that time, however, your bones could be quite weak. A bone density test makes it possible to know your risk of breaking bones before the fact.

A bone density test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone. A bone density test is a fairly accurate predictor of your risk of fracture.


Rockcastle Regional recently installed a new state-of-the-art MRI. The Seimens Magnatom Essenza, will provide high-quality imaging for Rockcastle’s radiologists, physicians and patients. The new MRI will offer more diagnostic precision, while offering the patient more comfortable exam.

MRI (Magnetic Resonance Imaging) uses a powerful magnetic field and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. This is a non-invasive, usually painless medical test that does not use radiation. Detailed images created by an MRI are better than those obtained by x-ray, ultrasound, or CT. Physicians use the MRI examination to help diagnose or monitor treatment for tumors of the chest, abdomen, or pelvis; lesions on the liver or other internal organs; tumors or abnormalities of the reproductive organs.

Digital Mammography

A mammogram is an x-ray of the breast. Mammograms can be used to check for breast cancer in women who have no signs or symptoms of the disease. This type of mammogram is called a screening mammogram. Screening mammograms usually involve two x-rays of each breast. They make it possible to detect tumors that cannot be felt. Screening mammograms can also find microcalcifications (tiny deposits of calcium) that sometimes indicate the presence of breast cancer.

Mammograms can also be used to check for breast cancer after a lump or other sign or symptom of breast cancer has been found. This type of mammogram is called a diagnostic mammogram. Signs of breast cancer may include pain, skin thickening, nipple discharge, or a change in breast size or shape. A diagnostic mammogram also may be used to evaluate changes found during a screening mammogram, or to view breast tissue when it is difficult to obtain a screening mammogram because of special circumstances, such as the presence of breast implants.

Rockcastle Regional has been awarded a three-year term of accreditation in mammography as the result of a recent review by the American College of Radiology (ACR). The ACR gold seal of accreditation represents the highest level of image quality and patient safety. It is awarded only to facilities meeting ACR Practice Guidelines and Technical Standards after a peer-review evaluation by board-certified physicians and medical physicists who are experts in the field.

Nuclear Medicine

Nuclear Medicine is a subspecialty within the field of radiology that uses very small amounts of radioactive material to diagnose or treat disease and other abnormalities within the body. It is commonly used to evaluate organ function such as diagnostic studies of the heart and kidneys. Nuclear imaging procedures are noninvasive and usually painless medical tests that help physicians diagnose medical conditions. These imaging scans use radioactive materials called a radiopharmaceutical or radiotracer. Physicians use nuclear imaging to visualize the structure and function of an organ, tissue, bone or system of the body.
