Radiology Services

Angiography is an X-ray exam of the arteries and veins to diagnose blockages and other blood vessel problems. Our angiography suite is equipped with the latest technology to diagnose conditions such as aneurysms, cerebral vascular disease, and blood vessel malformations.

Interventional radiologists perform this X-ray procedure, also called an angiogram. The procedure begins with the insertion of a thin catheter into the artery through a small incision in the skin, about the size of the tip of a pencil. A special X-ray dye is injected to make the blood vessels visible on the X-ray.

One of the most common reasons for an angiogram is to check for a blockage or narrowing in a blood vessel that may interfere with normal blood flow throughout the body. If a blockage is found, the radiologist may treat it without surgery at the same time the angiogram is being performed.

Computer-assisted tomography (CT) scans are among the full spectrum of the hospital’s radiological services.

The CT scan suite features a 64-slice and 16-slice scanner which uses low-dose radiation and computer manipulation to produce high quality images of all parts of the body. Also available is CT fluoroscopy, which allows the hospital’s interventional radiologists to perform surgical procedures such as biopsies and drainages with accuracy.

The helical low does CT scan can detect the earliest stages of lung cancer. This simple test is a non-invasive procedure that allows the pinpointing of even the smallest nodules, and the test takes only a few minutes.

An MRI uses magnetic fields and computers to create detailed images of the organs and tissues in multiple projections. No radiation is used with this modality. Many diseases are best detected and can only be seen with Magnetic Resonance Imaging. MRI biopsies of the breast are also performed.

Most MRI machines are large, tube-shaped magnets. When you lie inside an MRI machine, the magnetic field temporarily realigns hydrogen atoms in your body. Radio waves cause these aligned atoms to produce very faint signals, which are used to create cross-sectional MRI images — like slices in a loaf of bread.

The hospital’s MRI suite features an “extra wide” MRI that has a larger 70 cm opening, offering patients the benefits of an open MRI while providing physicians with quality images.

Nuclear Medicine

Nuclear medicine uses very small amounts of radioactive substances, or tracers, to diagnose or treat disease. It is a safe, painless way of gathering information that may otherwise be undetectable. Nuclear medicine tests can identify abnormalities early in the progression of a disease, long before the medical problem would be apparent with other diagnostic screenings.

Many different types of nuclear medicine tests are performed each day by our highly qualified staff to detect neoplasms, thyroid disorders, hypertension, cardiac disease, pulmonary disease, gastrointestinal problems, and renal dysfunction, among others.

PET (Positron Emission Tomography)/CT Infusion Scan

This sophisticated diagnostic tool is used to detect lymphoma, melanoma, lung cancer, and head and neck tumors. PET scan studies may also be used to evaluate liver conditions in cases of colorectal cancer. In neurology, the test can detect various brain disorders.

PET scanning is a safe, noninvasive diagnostic procedure that is comfortable for the patient and allows a whole-body examination in a single procedure requiring only one hour. This study combines CT imaging with physiologic nuclear imaging to detect abnormal tissue throughout the entire body.

Ultrasound, also called sonography, uses sound waves to create images inside of the body. Ultrasound is used to detect diseases of the breast, heart, liver, gallbladder, and kidneys. Ultrasound is also used for pregnant women to examine the fetus.

No radiation is involved in this non-invasive procedure. Image quality enhancement tools such as Differential Tissue Harmonics and Precision Imaging ensure accuracy and maximum diagnostic confidence.

An X-ray (radiograph) is a noninvasive medical test that helps physicians diagnose numerous medical conditions. Imaging with X-rays involves exposing a part of the body to a low dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging. X-rays are commonly used to evaluate the lungs, bones, joints, spine, abdomen, and gastrointestinal tract.

Also available: fluoroscopy (a moving picture X-ray in real time) , and IVP (kidney, ureters, and urinary bladder) studies.

X-ray services at the hospital are fully digital, including in our Emergency Room , for faster service to expedite treatment.
