What are the possible side-effects of an MRI scan?

 MRI scans are painless and thought to be safe. MRI scans do not use X-rays so the possible concerns associated with X-ray pictures and CT scans (which use X-rays) are not associated with MRI scans.

However:

  • Rarely, some people have reactions to the contrast dye which is sometimes used.
  • Pregnant women are usually advised not to have an MRI scan unless it is urgent. Although the scan is thought to be safe, the long-term effects of strong magnetic fields on a developing baby are not yet known.

There are no after effects from the scan. You can return to your normal activities as soon as the scan is over. The scan pictures are studied by a specialist who interprets them - a radiologist - who sends a report to the doctor who requested the scan. It is usual to have to wait for at least two weeks before hearing about your results. If there are any urgent findings, the specialist will be informed as soon as possible.see here

What are medical x-rays?

Image
click here X-rays  are a form of electromagnetic  radiation , similar to visible light. Unlike light, however, x-rays have higher energy and can pass through most objects, including the body. Medical x-rays are used to generate images of tissues and structures inside the body. If x-rays traveling through the body also pass through an x-ray detector on the other side of the patient, an image will be formed that represents the “shadows” formed by the objects inside of the body. One type of x-ray detector is photographic film, but there are many other types of detectors that are used to produce digital images. The x-ray images that result from this process are called radiographs.

overview of nuclear medicine?

Image
  What is nuclear medicine? Nuclear medicine  is a medical specialty that uses radioactive tracers (radiopharmaceuticals) to assess bodily functions and to diagnose and treat disease. Specially designed cameras allow doctors to track the path of these radioactive tracers. Single  Photon  Emission  Computed Tomography  or SPECT and Positron Emission Tomography or PET scans are the two most common imaging modalities in nuclear medicine. What are radioactive tracers? Radioactive tracers are made up of carrier molecules that are bonded tightly to a radioactive atom. These carrier molecules vary greatly depending on the purpose of the scan. Some tracers employ molecules that interact with a specific protein or sugar in the body and can even employ the patient’s own cells. For example, in cases where doctors need to know the exact source of intestinal bleeding, they may radiolabel (add radioactive atoms) to a sample of red blood cells taken from the patient. They...

What’s the difference between a PET scan, CT scan and MRI?

   Computed tomography (CT)   scans use X-rays.   Magnetic resonance imaging (MRI)   scans use magnets and radio waves. Both produce still images of organs and body structures. PET scans use a radioactive tracer to show how an organ is functioning in real time. PET scan images can detect cellular changes in organs and tissues earlier than CT and MRI scans. Your healthcare provider may perform a PET scan and CT scan at the same time (PET-CT). This combination test produces 3D images that allow for a more accurate diagnosis. Some hospitals now use a hybrid PET/MRI scan. This new technology creates extremely high-contrast images. Providers mainly use this type of scan for diagnosing and monitoring cancers of the soft tissues (brain, head and neck,  liver  and pelvis). click Here
