Advantages of MRI and Limitations, Cardiovascular

MRI provides information that differs from other imaging modalities. Its major technological advantage is that it can characterize and discriminate among tissues using their physical and biochemical properties (water, iron, fat, and extravascular blood and its breakdown products). Blood flow, cerebrospinal fluid flow, and contraction and

Low field MR disadvantages Questions and Answers

2020-6-11  Susceptibility artifacts are proportional to field strength, and although this may be an advantage for lower-field scanners for reduced metal artifacts, it may also be a disadvantage as well. In particular, lower-field units are inferior to high-field scanners in their ability to detect focal areas of calcification, iron accumulation, or

MRI Radiology Reference Article Radiopaedia

MRI (an abbreviation of magnetic resonance imaging) is an imaging modality that uses non-ionizing radiation to create useful diagnostic images.. In simple terms, an MRI scanner consists of a large, powerful magnet in which the patient lies. A radio wave antenna is used to send signals to the body and then a radiofrequency receiver detects the emitted signals.
