The main advantage of white blood imaging is its fast acquisition. It can obtain movement sequences and allows studying cardiac function and movement. #HEART RADI FREE#White blood imaging involves gradient echo sequences and steady-state free precession MRI (SSFP). In practice, the difference between the two is that SSFP is less vulnerable to the T2* effect. T2 and PD weighted sequences reach better tissue characterization.T1 weighted sequences achieve better anatomic definition.These can be T1, T2, or proton density weighted sequences: However, a low signal/noise ratio results in inferior spatial resolution. The fast acquisition time of the sequences minimizes respiratory and cardiac movement artifacts. Imaging Dark blood Imagingĭark blood imaging may be based on fast spin echo or double inversion recovery sequence. In particular, a comprehensive understanding of cardiac imaging planes is required for scan planning. MRI is generally inferior to cardiac CT for evaluation of the coronary arteries.Ĭardiac MRI can be technically challenging. MRI safety still requires consideration.dynamic imaging provides functional assessment.a large number of sequences are available.protocol can be tailored to likely differential diagnoses.In comparison to other techniques, cardiac MRI offers:
