METHOD FOR VISUALIZATION OF BASILAR ARTERY UPON LOW-FLOOR MAGNETIC-RESONANCE TOMOGRAPH

摘要

FIELD: medicine.;SUBSTANCE: one should apply phase-contrast method for obtaining the picture and T2-weighted records of the research conducted. The picture should be obtained due to inclining frontal plane of cerebral section towards auxiliary one, being parallel against the way of basilar artery. Instead of standard records of research it is necessary to establish the following parameters: the time for repeating the interval (time repetition, TR) = 3500 msec; time echo (TE) = 117 msec; the number of slices (No. Slices) = 8; slice's thickness = 5 mm; field-of-view -230; matrix 256x182, the number of acquisition (No. Acquisition) - 1.;EFFECT: higher quality of visualization.;4 dwg, 1 ex
