Abstract

On T1 weighted pulsing sequences, the majority of soft tissue masses are of low signal intensity and show high intensity signals on T2 weighting. There however is a subset of soft tissue masses of varied histology that shows high signal intensity on T1 weighted pulsing sequences. These masses have either fat or blood in their substance. Lipomatous and hemangiomatous lesions that did not show high-signal intensity on T1 weighting were also encountered and are discussed. Present experience with MRI of soft tissue masses suggests that there is a limited spectrum of entities that produce high-signal intensity T1 weighted soft tissue masses.

摘要

在T1加权脉冲序列上，大多数软组织肿块呈低信号强度，而在T2加权上呈高信号强度。然而，有一部分组织学类型各异的软组织肿块在T1加权脉冲序列上呈高信号强度。这些肿块实质内含有脂肪或血液。也遇到了在T1加权上未显示高信号强度的脂肪瘤和血管瘤病变并进行了讨论。目前对软组织肿块的MRI经验表明，产生T1加权高信号软组织肿块的病变种类有限。
