Abstract

SETTING OF THE THINNEST SLAB FOR TIME OF FLIGHT MRA OF BRAIN

*Akio Ogura PhD

ABSTRACT

Back Grounds: Generally, the imaging range of the brain MRA is determined in the subjectivity by the operator used by the plan image that a blood vessel is not depicted. However, a necessary blood vessel may not be often depicted by an error of the setting of the imaging area. Therefore, optimal Slab angle, thickness, distance in the setting index of the imaging range, and evaluation of the contrast were examined. Material & Methods: The brain MRA of 14 subjects was imaged in a wide area parallel to an OM line. The line which linked the arteria vertebral (the first cervical vertebrae curved section) to anterior cerebral artery (A3) was determined with an optimal slab base line, and the angle with the OM line was evaluated. The distance from the inferior margin of pons to the Slavic bottom end was measured as far as a cerebral aneurysm predilection blood vessel was included. Furthermore, the cerebrovascular contrast by the slave angle was compared. Results: The slave setting of the range was recommended in brain-MRA as an angle was 34.3 degrees, and the thickness was 63.5mm, and, as the distance from the inferior margin of pons was 33.9mm. The cerebrovascular contrast of the optimal slab base line angle did not have a significant difference for an OM-line.
