A Computed Tomography (CT) Scan is one of the most popular scanning exams utilizing multiple x-rays in a cross-sectional imaging technique. It is reliable in spotting abnormalities as opposed to a plain x-ray. CT scans, which show a 3-D image of the area of the body being examined, are used to support or help establish a diagnosis. CT scans can help detect brain injuries, bleeding within the body, blood clots, strokes, tumors, tissue damage, blood vessel blockages, bone malformations and more.
CT scans are also used for preventive medicine to diagnose patients with a high risk or family link to certain kinds of cancer and heart disease.
A mammogram is a special type of low-energy X-ray of the breast, commonly used to detect breast cancer. A mammogram allows physicians a closer look for changes in breast tissue that cannot be felt during a breast exam. Mammograms can show tumors before they are large enough to be felt during a breast exam.
SAMC uses digital mammography, allowing for mammograms to be stored electronically. Technology allows for image manipulation for clarity. Changing the contrast can provide improved visibility. The radiation is less in digital mammograms as opposed to traditional film mammograms. Because they are stored electronically, they are easily revisited and transmitted for further analysis when needed.
SAMC is the first hospital in the region to utilize the newest 3 Tesla MRI unit, the highest quality vascular imaging. The increased clarity of a 3T is particularly beneficial for pathological conditions involving the brain, spine and musculoskeletal system. The quality of the scan allows our board-certified radiologists to differentiate between benign and potentially hazardous medical conditions with confidence, providing you with earlier diagnosis and treatment. The 3T is efficient, allowing for shorter scan times and is more comfortable for the patient. A tesla is a unit of magnetic measurement. SAMC also utilizes two 1.5 Tesla MRI units.
A myelogram is an imaging procedure performed on an outpatient basis by a radiologist to diagnose medical conditions of the spinal canal, spinal cord and nerve roots. The procedure uses a combination of real time x-Ray imaging (fluoroscopy) and CAT Scans (CT). During the examination a contrast material or “x-ray dye” will be introduced into the spinal column with the use of a spinal needle. The images obtained during the myelogram will allow your physician to evaluate and treat your medical condition.
Myelography may be used in planning for surgical treatment of the spine. These high detailed images help to demonstrate:
- Compression of nerve roots caused by herniations of intervertebral discs
- Degenerative Changes in the bone and tissues surrounding the spinal canal
- Spinal stenosis
- Tumors involving the spine, nerve roots or spinal cord
- Infections involving the spine, the discs or surrounding tissues
- Spinal lesions caused by disease or trauma
- Spinal fluid leaks
X-ray technology uses electromagnetic radiation to make images. The image is recorded on a film or radiograph, and is used to determine the type and extent of a fracture and to detect pathological changes in the lungs, stomach, intestines and other parts of the body. x-rays help physicians diagnose various diseases or ailments. Radiographs can be produced using a variety of imaging methods, and they all require exposing the patient to X-ray radiation. The image or picture is basically a shadow of the parts of the patient that absorb or block the x-rays. The image can be collected on photosensitive film, on a digital imaging plate, or seen live on a fluoroscope – sort of like an x-ray TV camera.
Fluoroscopy, useful for catheter guidance, produces real-time images of the body employing a constant input of X-rays at a lower dose. Fluoroscopy is often used in image-guided procedures when constant feedback is required during the procedure.
Radiographs are usually taken by a trained registered radiology tech. The resulting images are then interpreted by a radiologist who makes a diagnosis or suggests further tests.
