• Scanning for Alzheimer’s

    In the fight against Alzheimer’s disease, being able to detect the disease before it progresses is crucial. One type of Alzheimer’s test that may be used is a PET scan, or positron emission tomography scan. A PET scan near San Antonio involves the use of a radioactive tracer to allow physicians to evaluate the function of organs and tissues. For patients suspected of having Alzheimer’s disease, the PET scan can reveal the accumulation of amyloid proteins .

  • Understanding the Benefits of an MRI

    mri san antonio tx There are many different types of medical images that can assist healthcare providers in diagnosing conditions and diseases, developing a treatment plan, and checking on the progress of the treatment. One of these is the magnetic resonance imaging (MRI) scan. Instead of using ionizing radiation, like an X-ray, an MRI uses radio waves, a computer, and a very strong magnet to produce medical images. Patients who have been referred for an MRI scan in San Antonio may wish to explore the benefits of this type of test before going to the imaging center.


    Radiology technologists strive to use the lowest possible amount of radiation for exams such as X-rays. However, many patients are still concerned about the possible effects of exposure to any amount of radiation. Some patients, such as children and women who are pregnant, must avoid radiation altogether. Since MRI machines do not use any radiation at all, they are widely regarded as exceptionally safe for patients. Another advantage of an MRI scan is that it is a noninvasive approach to diagnosis, which means it’s a safer alternative than an angiography for a patient suspected of having heart or blood vessel problems. Sometimes, a medical imaging test calls for the use of contrast dye, which facilitates an accurate interpretation of the images. The contrast dye that is used for a patient undergoing an MRI scan is less likely to result in an allergic reaction compared to the iodine-based contrast dye used in other tests.


    Another benefit of MRI scans is their versatility. The images produced by the MRI machine can aid healthcare providers in detecting a wide range of medical problems and in developing a treatment plan. MRI scans are used to diagnose cancer, bone abnormalities, muscular problems, and heart and vascular disease. They can reveal injuries, liver disease, and abnormalities of the spinal cord and brain. MRI exams may also be used to explore the possible causes of pelvic pain in women, such as uterine fibroids and endometriosis.
