Witryna8 lut 2024 · Furthermore, artifacts, or errors in the MRI images, can be caused by foreign bodies being affected by the magnets. This means that in some specific cases, a 1.5T scanner is recommended, due to reduced risk and better image quality. Overall, the main deciding factor between a 1.5 T and 3.0T MRI scan is the body part being imaged. WitrynaAs frequency increases the dielectric term (J D) becomes more important, but even at 7.0T (300 MHz) the conductive/displacement current ratios for fat, gray matter, muscle, and CSF are approximately 0.4, 0.6, 0.7 and 1.7 respectively.
