| Plain radiography, also known as x-ray, uses small amounts of radiation that
are passed through a selected part of the body to produce an image on film. Radiography is commonly
used for evalution of the chest, musculoskeletal system, and when used in conjunction with contrast
agent, the gastrointestinal system. More information. |
 |
|
| A Barium Enema is an x-ray examination of the large intestine, also known as the colon. This includes the right or ascending colon, the transverse colon, the left or descending colon and the rectum. The appendix and a portion of the small intestine may also be included. More information.
|
|
| Computed tomography (CT or CAT) scan is a special kind of x-ray examination
that produces detailed cross-sectional images of internal organs and soft tissue.
CT is commonly used to evaluate abnormalities of the brain, neck, spine, chest, abdomen, and
musculoskeletal system. It is especially helpful in the rapid diagnosis of traumatics injuries
and in guiding needle biopsies. Very fast scanners that improve patient comfort and decrease
the scan time and radiation dose are now available at UCSF. More information. |
 |
|
| Diagnostic X-Rays, is an x-ray that involves exposing a part of the body to a small 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. More information. |
|
| Discograms, Nerve Blocks A discogram is an enhanced X-ray examination of the intervertebral discs. Contrast dye is injected into the center of the injured disc(s). The dye makes the disc visible on a fluoroscope (special X-ray screen). More information.
|
|
Hysterosalpingography is an x-ray examination of a woman's uterus and fallopian tubes that uses a special form of x-ray called fluoroscopy and a contrast material. More information.
|
|
| Interventional and Neuro Interventional Radiology is a subspecialty that performs minimally invasive procedures
with catheters and other small devices for opening blocked blood vessels,
draining excess fluids, relieving hypertension, removing foreign bodies, and managing
gastrointestinal bleeding. More information. |
 |
|
| Lumbar Puncture with X-Ray guidance A lumbar puncture is a diagnostic and at times therapeutic procedure that is performed in order to collect a sample of cerebrospinal fluid for laboratory analysis, or rarely to relieve increased intracranial pressure. X-Rays pictures are used to image the spine. More information.
|
|
Magnetic resonance imaging (MRI) is a noninvasive imaging exam that uses a strong magnetic field and computer processing to provide pictures of internal organs and tissues. MRI is commonly used to image the brain, spine, chest, abdomen / pelvis, vessels, bones and muscles. Unlike a CT exam, MRI does not involve any radiation (X-rays). More information. |
 |
|
| Myelography is an imaging examination that shows the passage of contrast material in the space around the spinal cord (the subarachnoid space) using a real-time form of x-ray called fluoroscopy, in which organs can be seen over time. More information. |
|
| Nuclear medicine scans provide information about organ functions by imaging the concentration of radioactive compounds within certain parts of the body. These compounds, or radioisotopes, are given to patients in small amounts by a specially trained technologists in order to evaluate for abnormalities in bone, liver, lungs, heart, brain, kidneys and the endocrine system. More information. |
 |
|
| Positron emission tomography, also called PET imaging or a PET scan, is a diagnostic examination that involves getting images of the body based on the detection of radiation from the emission of positrons. Positrons are tiny particles emitted from a radioactive substance administered to the patient. More information. |
|
| Radiofrequency Ablation is the method of choice for treating osteoid osteoma (a benign tumor of the bone). During this procedure the tumor is heated up for a period of approximately 6 minutes and thus abladed. This procedure is minimal invasive, is done on an outpatient basis and has a short recovery time. More information. |
 |
|
An Upper GI (Gastrointestinal) series is an x-ray examination of the pharynx, esophagus, stomach and first part of the small intestine (also known as the duodenum) that uses a special form of x-ray called fluoroscopy and a contrast material called barium. More information. |
|
Ultrasound imaging, also called ultrasound scanning or sonography, involves exposing part of the body to high-frequency sound waves to produce pictures of the inside of the body. More information. |
 |
|
| Virtual CT Colonoscopy Scan CT colonography uses CT scanning to obtain an interior view of the colon (the large intestine) that is ordinarily only seen with an endoscope inserted into the rectum. More information. |
