查询词典 scans

Curvilinear calcification suggests an aneurysm but is a less specific finding because it can also occur in craniopharyngiomas and sphenoidal masses. The intense enhancement of the residual lumen is relatively specific, but differentiation from other masses may be difficult on CT scans depending on the timing and degree of vascular enhancement. The MR imaging features are usually diagnostic, although they can be very subtle [2]. Significant signal heterogeneity is seen with T1 hyperintense signal due to subacute thrombus or flow related enhancement. Areas of T2 hypointensity can be seen due to intracellular deoxy or methemoglobin, calcification, or flow void.

线样钙化提示动脉瘤，但不是一个非常特异的征像，因为这也可以见于颅咽管瘤和蝶骨肿瘤，管腔样明显强化更特异些，但是在CT上与其他肿瘤鉴别可能是困难的，因为这取决与增强的时间与血管强化的程度，MR的特征性表现是更具有诊断意义的，即使有时候可能表现的非常细微，在T1上可以看到明显的不同信号成分，这是由于亚急性的血栓或流动相关增强效应，T2序列上可以看到低信号区域，这是由于细胞内脱氧或高铁血红蛋白，钙化，或流空效应。
