Wikipedia

  1. MRI

    Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from CT and PET scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of disease. Compared to CT, MRI provides better contrast in images of soft-tissues, e.g. in the brain or abdomen. However, it may be perceived as less comfortable by patients, due to the usually longer and louder measurements with the subject in a long, confining tube, though "Open" MRI designs mostly relieve this. Additionally, implants and other non-removable metal in the body can pose a risk and may exclude some patients from undergoing an MRI examination safely. MRI was originally called NMRI (nuclear magnetic resonance imaging), but "nuclear" was dropped to avoid negative associations. Certain atomic nuclei are able to absorb radio frequency energy when placed in an external magnetic field; the resultant evolving spin polarization can induce a RF signal in a radio frequency coil and thereby be detected. In clinical and research MRI, hydrogen atoms are most often used to generate a macroscopic polarization that is detected by antennas close to the subject being examined. Hydrogen atoms are naturally abundant in humans and other biological organisms, particularly in water and fat. For this reason, most MRI scans essentially map the location of water and fat in the body. Pulses of radio waves excite the nuclear spin energy transition, and magnetic field gradients localize the polarization in space. By varying the parameters of the pulse sequence, different contrasts may be generated between tissues based on the relaxation properties of the hydrogen atoms therein. Since its development in the 1970s and 1980s, MRI has proven to be a versatile imaging technique. While MRI is most prominently used in diagnostic medicine and biomedical research, it also may be used to form images of non-living objects, such as mummies. Diffusion MRI and functional MRI extend the utility of MRI to capture neuronal tracts and blood flow respectively in the nervous system, in addition to detailed spatial images. The sustained increase in demand for MRI within health systems has led to concerns about cost effectiveness and overdiagnosis.

  1. mri

    MRI, or Magnetic Resonance Imaging, is a medical imaging technique that uses strong magnetic fields and radio waves to generate detailed images of the inside of the body. It is non-invasive and can visualize the structure and function of various organs and tissues, helping in the diagnosis and treatment of medical conditions.

  1. Mri

    The mri are a fictional alien species in the Faded Sun Trilogy of C. J. Cherryh's Alliance-Union universe. Their culture appears to be drawn upon those of the Apache, Berbers, and Japanese samurai. Their name means simply "the people," and they refer to all other races as "tsi-mri," which literally means not people.

    Unfortunately, I'm having some issues with my pec muscle. Right now I can't actually serve it's kind of hard to play, i'm having an MRI( scan) tomorrow, I'm going to stay here to see the doctors and see as many specialists as I can. I won't know( how serious the injury is) until I get those results.

  3. Katherine Bentley:

    This program helped me learn that the mind and body are connected, with Franny, she had two MRI’s she had an ultrasound, she had a lot of testing done and everything was normal. So I can say, ‘Franny, I know your left can handle your weight, but we just need to stand on it.’ Some of it is just reassurance.

    I recived an MRI "test" becuase I had three seisures. at that time I was feeding my wife who had (dementia) serious memory problems. I was taken to the (emergency room) where the doctor perfomed an operation on my brain referred to a "bleed". Why was the MRI perfomed on my brain? No one disclossed this to me.
