Web脳ドックのmriのt2スターとは? 脳ドックにおける各種MRI、MRA検査の中にT2と呼ばれる検査方法があります。 そういった検査はいわゆる撮影項目に分類されるもので全てが最初から脳ドックの検査項目に取り入れられているわけではありません。 T2*-weighted imaging is an MRI sequence to quantify observable or effective T2 (T2* or "T2-star"). In this sequence, hemorrhages and hemosiderin deposits become hypointense. See more T2*-weighted imaging is built from the basic physics of magnetic resonance imaging where there is spin–spin relaxation, that is, the transverse component of the magnetization vector exponentially decays towards its … See more T2*-weighted sequences are used to detect deoxygenated hemoglobin, methemoglobin, or hemosiderin in lesions and tissues. Diseases with such patterns include intracranial hemorrhage, arteriovenous malformation, cavernoma, hemorrhage in a … See more • MRI sequence See more
