MRI Versus CatScan

The Difference Between MRI and Catscans

Diagnostic studies that use radiology assist healthcare physicians to determine the internal structures of the human body.  Medical Professionals and Radiologists utilize these images for many reasons to diagnose the cause of specific symptoms, monitor internal body changes as a response to treatment for a certain ailment and as preventative cares such as testing for breast cancer or heart disease.

Magnetic Resonance Imaging (MRI) uses large strong magnets and specific radio waves to manifest images.  Although MRI diagnostics don't create images very well for bone, they are exceptional for soft tissues.  Radio waves are sent through the human body.  An antenna picks up the signal emitted from the cell's hydrogen atoms.  Different radio waves can change the contrast of the image along with contrast agents.

Catscans are completely different and are considered a specialized x-ray.  A tube rotates around the patient while the computer translates the images into pictures that are actual slices in picture form of the specific body part and therefore is usually the preferred choice of diagnostic imaging when it comes to bone structures.

  1. Stopping by from sits– My daughter had an MRI when she was six mtohns old and it was the worst thing ever watching helplessly ad they pricked her four times trying to find a vein for the anesthesia ! You are right about that part being awful– I will pray that god gives the doctors and nurses wisdom and some comfort for you and your kiddo!

    • The US spends 16% of GDP on haleth care, because it is the best place in the world to get haleth care this isn’t true, US care (performance, not cost) is comparable with all the other developed nations ( international medical error rates). Plus 47 million Americans have no coverage (45,000 die every year as a result). Also under the private system, billions and billions are wasted on: lawsuits, company profits, non-paying patients etc

  3. That’s awful. Glad to be the listening ear so you don’t have to go poastl (medical?) on the “team”. I hope you get the healing you need for your neck. I have a “pen-throwing neck” from time to time. Ask my kids. They’ve learned a lot of useful vocabulary.
