DIFFERENCE BETWEEN CT SCANS AND MRI

Image
  You might have heard some time or another, CT scan and MRI and must have always wondered what is the difference between the two. Though both are methods for imaging internal body parts, and also have an almost similar use, the way they are produced is different. CT scans use X-rays while MRI uses strong magnet waves and radio waves. A CT scan or the CAT scan stands for Computerized Axial Tomography, wherein a large X-Ray machine called a CT scanner sends the image to the computer. MRI or Magnetic Resonance Imaging uses radio waves and magnets to create images. In this scan, the constant magnetic field and radio waves bounce off the water molecules and fat cells in the patient’s body. Though CT scans are very common as they are cheaper than MRIs, MRI produces detailed and accurate images of the body. The very common uses for a CT scan include examining or looking for a tumor, bone fractures, internal bleeding, cancer development, and response to a particular treatment....

WHAT IS THE PURPOSE OF A CT SCAN?

        Computed Tomography or as commonly referred to as CT scan is a diagnostic imaging procedure that requires a combination of X-Rays and computer technology to produce images of the inside of the body. When a doctor asks for a CT scan, it is usually when they want to detect or monitor diseases and conditions as such, cancer, heart disease, lung nodules, and liver masses, internal injuries, internal bleeding. CT scan is also very useful to monitor the effectiveness of certain treatments, such as cancer treatment. In a CT scan, the X-ray beam moves in a circle around the body. This allows multi-view of the same organ and thus provides the information of their structure with much greater detail. This X-ray information is then sent to a computer that then interprets this data, displaying it in a two-dimensional form on the monitor.        A CT scan gives detailed images of any part of the body which also includes the bones, muscles, fat, or...
