Abstract

Magnetic resonance (MR) is rapidly emerging technique that provides high quality images and potentially provides much more diagnostic information than do conventional imaging modalities. MRI is conceptually quite different from currently used imaging methods. The complex nature of MRI allows a great deal of flexibility in image production and available information, and key points are as follows. 1. MR offers a non-invasive technique with which to generate in vivo human images without ionizing radiation and with no known adverse biological effects. 2. Imaging mechanism of MRI is quite different from conventional imaging modality and for more accurate diagnostic application, It is necessary for physician to understand imaging mechanism of MRI 3. M.R. makes available basic chemical parameters that may provide to be useful for diagnostic medical imaging and more specific pathophysiologic information which are not available by alternate techniques. 4. M.R. can be produced by number of different methods. This flexibility allows the imaging technique to be applicated for particular clinical purpose. Multiplanar and three dimensional imaging may extend the imaging process beyond the single section available with current CT. 5. Future directions include efforts to; a. Further development of hard ware b. More fastening scan time c. Respiratory and cardiac gated imaging d. Imaging of additional nuclei except hydrogen. e. Further development of contrast media f. MR in vivo spectroscopy g. Real time MR imaging
