That doesn’t mean anything is seriously wrong, it is just the way most back pain behaves. Back pain often recurs and it is typical for your symptoms to come and go. Your best approach would be to follow the self-care measures described at right. If none of these additional symptoms is present, you probably don’t need an imaging test. Abnormal reflexes, or loss of muscle power or feeling in the legs.“Red flags” that can alert your health care provider that imaging may be worthwhile include: It can be a good idea to get an imaging test right away if you have signs of severe or worsening nerve damage, or a serious underlying problem such as cancer or a spinal infection. Those findings can cause needless worry and lead to unnecessary follow-up tests and procedures such as injections or sometimes even surgery. Furthermore, the tests often reveal spinal abnormalities that could be completely unrelated to the pain. That’s especially worrisome to men and women of childbearing age, because x-rays and CT scans of the lower back can expose testicles and ovaries to radiation. While back x-rays deliver less radiation, they still can give 75 times more radiation than a chest x-ray. Length of MRI Scanĭepending on the area of concern, an MRI test can last between 30 and 60 minutes.X-rays and CT scans expose you to radiation, which can increase cancer risk. During the scan, the technician will watch you from another room to ensure you are comfortable and give updates on the status of the exam. X-rays, CT scans, and MRIs are called imaging tests because they take pictures, or images, of the inside of. The dye helps the radiologist see certain areas more clearly. You probably do not need an X-ray, CT scan, or MRI. Some exams require a special dye (contrast), which is given through a vein (IV) in your hand or forearm before the test. What to expect during a MRIīefore an MRI procedure, you will be asked to remove all metal to avoid interaction with the magnet inside the MRI equipment. Instead, MRI images are generated by pulsing radio wave energy through the body to produce cross-sectional pictures of organs and internal structure in the body.
MRIs are used to detect diseases or abnormalities throughout the body, such as brain aneurysms or tumors, but also are often used as a “second look” if other imaging scans provide inconclusive results. Request Appointment What Is Magnetic Resonance Imaging (MRI)? How does an MRI work? MRI scan Magnetic resonance imaging (MRI) is a diagnostic imaging procedure that uses a combination of a large magnet, radio frequencies and a computer to. The contrast will be provided to you when you arrive for your test. Radiologists analyze the CT scan results to help diagnose disease or injury to:Ĭomplete scans usually take only a few minutes. This allows the radiologist to highlight certain areas for a clearer image. In this study, the difference in slip distance between MRI and plain radiography was not found to be statistically significant. Often times you will be asked to drink a contrast for the CT scan. You will be asked to remain still during the exam to avoid blurred images. A computer creates many different CT scan images of the body, called slices, which can be viewed on a monitor by the radiologist. Once you are inside the scanner, the machine’s x-ray beam rotates around you. What to expect during a CT scanĭuring a CT scan procedure, you will be asked to lie on a table that slides into the center of the CT scanner. Comparison of MRI versus xray for imaging scoliosis of the spine. CT scans can also diagnose an infection, however they can also be used to guide a surgeon to the right area during a biopsy, identify masses and tumors, including cancer, and study blood vessels. Scoliosis xrays that check the spine can be harmful due to radiation & cancer risk. A CT scan uses data from several x-ray images of structures inside the body and converts them into CT scan pictures. What Is a Computed Tomography (CT) Procedure? How does a CT scan work?ĭoctors use CT scans primarily to look at the soft tissues of the body and various organs. Magnetic Resonance Imaging (MRI), like x-rays and CT scans, is a non-invasive imaging technology unlike x-rays and CT scans, MRI produces three dimensional. The length of the x-ray depends on the body part being examined however it typically takes a matter of minutes. This exam is painless, however it may require you to stand still for a short period of time which can cause temporary discomfort.
These X-ray images, called “radiographs,” are a result of a shadow cast between the x-ray source and the x-ray detector to capture images of different tissues or bones inside the body. In this exam, an x-ray machine sends individual x-ray particles through the body, which are recorded as digital x-ray images on a computer. Doctors commonly use x-ray technology to diagnose broken bones, but can also detect pneumonia, types of cancers, and other developing conditions.
