• What to Tell Your Radiologist Before Your Imaging Test

    If you have been referred to an imaging center in San Antonio for testing, your radiologist will discuss the procedure with you and tell you how to prepare. It’s important for you to alert your radiologist to any conditions or concerns you may have that could interfere with the test. To make sure your medical imaging test is as safe and effective as possible, be sure to discuss these factors with your radiologist. radiologist - scan

    Pregnancy

    Your radiologist needs to know if you are pregnant or if you could be pregnant. Some imaging tests and some of the tracers used for imaging tests are not safe for a developing fetus. If you are pregnant, X-rays, CT scans, and nuclear medicine tests may not be safe. Ultrasounds and MRIs are generally considered to be acceptable during pregnancy, but your radiologist and doctor will work together to make the right decision for you.

    Claustrophobia

    Some medical imaging tests ask patients to stay in a certain position or enclosed area for an extended period of time. For some people, this can trigger symptoms of claustrophobia. If you are concerned about experiencing claustrophobia during your imaging test, then let your radiologist know. He or she can offer advice that could make you feel more confident about the test. Your doctor may also provide you with a sedative to make the test more comfortable.

    Implanted Devices

    Make your radiologist aware of any implanted devices you have, so that he or she can make the appropriate adjustment to your test. Joint replacement implants and breast implants can affect the appearance of your medical imaging test and may interfere with the ability to see certain parts of your anatomy. Some implanted devices, such as pacemakers, are not compatible with certain types of imaging tests, as the tests can disrupt the way the device works. Inform your radiologist about any implanted devices you have, even if they are not in the area of your body that is being scanned.

  • Get the Facts About Radiopharmaceuticals

    Radiopharmaceuticals are oral or injectable forms of radiation that are sometimes used during medical imaging tests. If you are referred for a PET scan in San Antonio , a radiopharmaceutical will be administered before your test. The dose of radiation is low and is safe for most people. Before your test, your doctor will weigh the risk of the test versus the benefits of having it, so you can feel confident that taking the radiopharmaceutical is worthwhile. Here are the facts you need to know about the use of radiopharmaceuticals during medical imaging. medical - imaging

    Radiopharmaceuticals leave your body quickly.

    During a PET scan, you will take a form of radiopharmaceutical called FDG. FDG is a form of glucose that is radioactive. It is highly controlled and tested for safety and has a half-life of about 110 minutes. As a result, the body expels it quickly. The majority of the FDG completely decomposes in the body, and the rest is removed through urine. Unlike some forms of radioactive medicine, there is no need to be sequestered from your family to protect them from radiation. Approximately 90% of the FDG will be gone from your body before you leave the testing center.

    The radiopharmaceutical is absorbed by the organ being tested.

    During a PET scan, the radiopharmaceutical that is administered is absorbed by the organ your doctor wants to examine. This makes the organ easier to see and helps to highlight any abnormalities. If you have cancer, using a radiopharmaceutical also allows your doctor to see if a tumor is active, rather than just seeing the structure of it, as you can on other imaging tests.

    Some patients cannot use radiopharmaceuticals.

    In some cases, allergies prevent patients from being able to use radiopharmaceuticals. You may also not be able to use them during breastfeeding or if you are on medications that could trigger a dangerous interaction. Typically, radiopharmaceuticals are safe during pregnancy, but your doctor will make the decision based on your specific health needs.

  • Preparing for a PET Scan

    Early disease detection is an essential part of staying healthy, and scheduling a PET scan in San Antonio can help you remain well long-term. Positron emission technology (PET) can identify changes in the body at the cellular level and evaluate your tissue and organ function.

    Preparing for Your PET Scan

    PET Scan Imaging Most people will be asked to consume no food and only water for several hours before the PET scan in scheduled, and patients who are diabetic will be given special instructions for their procedure. Because any food in your stomach may interfere with the distribution of the radioactive tracer, it’s vital to adhere to these pet scan prep instructions to avoid having to reschedule your appointment. Be prepared to remove any metal hairpins, jewelry, and eyeglasses before your test, as well as removable dental work or hearing aids. Some patients may be asked to change into a gown for the scanning process.

    How PET Scans Work

    PET scans are done using a large machine with a hole through the middle that looks much like an MRI or CT unit. Radioactive material is injected into the bloodstream, swallowed, or inhaled, and then accumulates in the target area of the body. The energy that this material emits is detected by the machine, revealing information about organ and tissue structure, chemical activity, metabolism rates, and other information. The scanner records this data, which is then transformed into images using a computer.

    PET Scan Procedure

    Most PET procedures are painless and are not considered to be extremely uncomfortable. During the scan, you’ll need to remain as still as possible to ensure clear and accurate images. Most people can resume their normal activities after the scan unless informed otherwise by their physician, and any special instructions will be given to you before you leave the imaging center. It’s recommended that patients drink plenty of water after the procedure to help flush the radioactive material from their system.

  • The Many Uses of Radiology

    Radiology plays a central role in diagnostic and therapeutic interventions. Doctors rely on radiology centers near San Antonio to conduct imaging tests such as X-rays, MRI scans, mammograms, and many other medical imaging exams. When you watch this video, you’ll get a basic overview of the many ways radiology affects healthcare around the world.

    This radiologist explains that radiology is a specialty branch of medicine that can be used on an inpatient, outpatient, or emergent basis. Doctors rely on radiology exams to explore the cause of symptoms, confirm diagnoses, conduct treatment planning, and monitor the body’s response to treatment. Some medical imaging exams, like X-rays and mammograms, use radiation. Others, like ultrasounds, do not. If you’re expecting to have a medical imaging test performed, your doctor or radiology technologist can help you learn what to expect from the exam.

  • How Does a PET Scan Work?

    Your doctor may refer you to an imaging center for a positron emission tomography (PET) scan. This is a type of diagnostic imaging study that allows your doctor to study diseases and bodily responses. When you make an appointment for your PET scan at the San Antonio-area facility, you may hear the term “nuclear medicine.” Nuclear medicine is a specialized branch of radiology that involves the use of very small amounts of radioactive material. This may sound unsettling; however, you can rest assured that your PET scan will be painless.

    What PET Scans Are Used For

    Radiology You may be referred to a radiologist for a PET scan for a variety of reasons. PET scans play a central role in diagnosing and staging cancer. They can also be used to assess how effectively a particular treatment is killing cancer cells. PET scans can allow for the evaluation of heart and brain function, and they can help doctors assess the flow of blood to the heart. A doctor may order a PET scan when a patient has suffered a heart attack or is suspected of having brain tumors. It is even possible to use data from PET scans to pinpoint the early changes associated with Alzheimer’s disease.

    How PET Scans Work

    First, the radiologist injects radioactive glucose into the patient . This is also known as a radiotracer. This substance gives off radioactive emissions, which are detected by the imaging device. The data are translated into images for evaluation. PET scans may sometimes be combined with computed tomography (CT) scans or magnetic resonance imaging (MRI) scans. This practice is referred to as image fusion. By combining information from two exams, patients may benefit from more accurate diagnoses.

    What Happens During the Test

    The imaging center provides patients with PET scan prep instructions. You’ll need to disclose your health information, such as whether you’re pregnant, could be pregnant, or are breastfeeding. Provided you are not a diabetic, you’ll be asked to consume nothing but water for several hours before the appointment. During the test, you’ll lie comfortably on an exam table as the radiotracer is injected. After about an hour, you’ll be moved into the scanner. A PET scan takes about 20 to 30 minutes to complete.
