MRI (Magnetic Resonance Imaging) technology has been commonly used as a non-invasive medical test for diagnosing medical conditions. Most hospitals utilize 1.5T MRIs, but San Antonio offers patients 3Tesla technology and 1.5 Tesla Wide Bore, which produces images with greater clarity and detail. Patients who experience stroke and patients undergoing brain surgeries are among the chief beneficiaries of MRI technology, but it is also used for imaging the spine, muscles, bones, joints, and breast tissue. Wide Bore is also available for patients who maybe anxious about confined spaces.
CT scans, sometimes called CAT
scans, are one of the diagnostic tools doctors use to reveal cancer within the
Using an advanced x-ray unit
that rotates around your body and a powerful computer to create cross-sectional
images, like slices, of the inside of your body—the CT scan clearly reveals
bones and organs and their inner structure, plus a detailed anatomy of the
pancreas, adrenal glands, kidneys, and blood vessels.
A radiologist, a physician
specifically trained to supervise and interpret radiology examinations,
analyzes the images and sends a signed report to your primary care or referring
physician, who will share the results with you.
A radiograph or x-ray is a non-invasive medical test that helps physicians diagnose and treat medical conditions. Some of the most frequent uses of x-rays are to obtain images of bones and joints, and the chest. The images are interpreted by a radiologist using a computer and special high resolution monitors. The radiologist is a physician who specializes in diagnosing and treating disease and injury using medical imaging.
Our Women's Breast &
Imaging Center at San Antonio Regional Hospital features digital mammography,
which is an advanced type of imaging that uses a computer, rather than x-ray
film, to record x-ray images of the breast.
Diagnostic x-rays use
invisible electromagnetic energy beams to produce images of internal tissues,
bones, and organs on film or digital media.
Digital mammography is
different from standard mammography. With digital pictures, the physician can
zoom in, magnify, and optimize different parts of the breast tissue in the
picture without having to take an additional image.
San Antonio Regional
Hospital's Endoscopic Services Department performs a vital function in the
early detection and identification of diseases and abnormalities. The colon,
esophagus, stomach, and gall bladder can all be examined and evaluated using a
videoscope or tiny camera.
During a procedure, patients
are provided moderate sedation for comfort. Procedures usually take less than
30 minutes and patients are sent home shortly thereafter.
These short and simple
procedures can provide an early diagnosis, which may save your life. We
encourage you to talk to your physician about any specific questions or
concerns that you may have. You may also call our Endoscopic Services
Department weekdays, from 6 am to 4 pm, at 909.920.4991.
The Gamma Knife is an advanced brain surgery device that permits outpatient brain surgery with no incision, minimal discomfort, and a brief recovery. Developed in Sweden in the 1950s, the Gamma Knife has been in use in the United States for more than two decades, providing patients with a treatment option for brain disorders that were once only treatable by open skull surgery. Over half a million patients have been treated with Gamma Knife surgery. In fact, Gamma Knife is the only radiation therapy system specifically licensed by the FDA for irradiating brain metastases. With unsurpassed and proven clinical outcomes, the Gamma Knife is the gold standard incranial radiosurgery.
Nuclear Medicine is a medical
specialty that uses safe, painless, and cost-effective techniques to diagnose,
treat, manage, and prevent serious diseases. Nuclear Medicine focuses on organ
function and structure, while radiology centers on anatomy.
Nuclear Medicine imaging procedures
often identify abnormalities early in the progression of a disease, long before
some medical problems are apparent with other diagnostic tests. Early detection
may allow for earlier treatment of the disease and increase the potential for a
more successful outcome.
We have three cameras
available for imaging at San Antonio Regional Hospital: a triple head whole
body scanner, a triple head cardiac scanner, and a multi-purpose single head
scanner. This equipment represents the latest technology for conducting planar
and SPECT (single photon emission computerized tomography).
Examinations are scheduled
weekdays, from 7:30 am to 4:30 pm. If you have questions about your test,
please contact your physician or the Nuclear Medicine Department at
Radiation Oncology, also known as Radiation Therapy, is the medical specialty that treats cancer with radiation and is part of our Cancer Services. It is administered in the form of gamma rays or x-rays designed to destroy cancer cells, while allowing the adjacent normal cells to repair themselves. Radiation is the preferred form of treatment for some types of cancer, and in other cases it is used in conjunction with surgery or chemotherapy.
Ultrasound procedures are used
to assess soft tissue structures such as muscles, blood vessels, and organs.
Ultrasound uses a transducer
that sends out ultrasonic sound waves at a frequency too high to be heard. When
the transducer is placed at certain locations and angles, the ultrasonic sound
waves move through the skin and other body tissues to the organs and structures
within. The sound waves bounce off the organs like an echo and return to the
transducer. The transducer picks up the reflected waves, which are then
converted by a computer into an electronic picture of the organs or tissues
