Results of MRI at 0.15T in twelve successive patients with intracerebral haematoma are reviewed. Using T2 weighted spin echo (SE) and partial saturation (PS without a refocussing 180 degree pulse) sequences, low intensity areas were seen in eleven of the twelve cases. These included central regions (three cases), a peripheral rim (seven cases) and more diffuse patterns involving the brainstem and cerebral hemispheres (two cases). One case initially displayed a peripheral rim and later a central low intensity region. Central low intensity regions were seen in acute, subacute, and chronic cases. Follow up in five cases displayed an increase in signal within the haematoma in three cases and a decrease in signal intensity in two cases. Low signal intensity areas can be seen within and around intracerebral haematomas imaged with T2 weighted sequences at low field strength.
回顾了12例连续的脑内血肿患者的0.15T磁共振成像（MRI）结果。使用T2加权自旋回波（SE）和部分饱和（无180度重聚焦脉冲的PS）序列，12例中有11例可见低强度区域。这些区域包括中央区（3例）、周边边缘区（7例）以及累及脑干和大脑半球的更弥漫性模式（2例）。1例最初显示周边边缘区，随后出现中央低强度区域。中央低强度区域可见于急性、亚急性和慢性病例。5例随访显示，3例血肿内信号增强，2例信号强度降低。在低场强下用T2加权序列成像的脑内血肿内部及周围可见低信号强度区域。
