Brain Imaging with MRI and CT presents over 180 disease processes and normal variants, grouping entities by these basic patterns to accentuate differential diagnostic features. High quality CT and MRI scans show multiple typical and distinguishing images for each entity. Common and unusual clinical ...

Abdomen:MRI is superior to CT and ultrasound for imaging solid organs such as the liver, spleen, pancreas, and kidneys. Ultrasound or CT is the preferred method for detecting gallstones or urinary tract stones, while MRI can be used to determine the location of blockages. Barium swallow or ...

MRI显然是金标准。弥散加权成像 (DWI)异常反映了实际的脑缺血区域,但但是 MRI 很慢而且很麻烦。 相比来说CTP更为方便快捷,并且只需要几分钟。 这是刚刚讨论过的患者的 CT 灌注。自动算法计算缺血核心和半影并对其进行颜色编码。核心梗死是粉红色的,缺血区域是绿色的,两者之间存在巨大的不匹配。不匹配区域就是Mismat...
