  • Computed Tomography (CT) Scans

    CT scans, sometimes called CAT scans, are one of the diagnostic tools doctors use to reveal cancer within the body.

    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.

    Diagnostic Radiology (x-rays)

    Diagnostic x-rays use invisible electromagnetic energy beams that produce images of internal tissues, bones, and organs on film or digital media.

    Depending on the area of your body to be x-rayed, you may be asked not to eat or drink prior to your x-ray. In other cases, you will be given special contrast agents to enhance or highlight specific body areas.

    Digital Mammography

    Our Women's Breast & Imaging Center at San Antonio Community 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.

    Ultrasound

    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 under study.

    Nuclear Medicine

    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 Community 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 909.920.4977.

    Magnetic Resonance Imaging (MRI)

    An MRI is a procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. These pictures can show the difference between normal and diseased tissue.

    MRIs produce better images of organs and soft tissue than other scanning techniques, such as computed tomography (CT) or x-ray. The MRI is especially useful for imaging the brain, the spine, the soft tissue of joints, and the inside of bones.

    San Antonio Community Hospital's new MRI system has exceptional image quality and is about twice as fast as older models. Not only will patients spend less time having their MRI, they will also be more comfortable.
