灶

The imaging finding mostly manifested as malacia and chronic hemorrhagic foci.

损伤的表现主要为软化灶和陈旧出血改变。

Enhancement emerge d around the operative area in early postoperative period shows tendency of gradual reduction or disappearance until malacia appears in the original enhancement area.

术后早期在术区边缘出现的增强，追踪观察有逐渐减弱或消失的趋势，直至在原增强部位形成软化灶。

Enhancement emerged around the operative area in early postoperative period show s tendency of gradual reduction or disappearance until malacia appears in the original enhancement area.

术后早期在术区边缘出现的增强，追踪观察有逐渐减弱或消失的趋势，直至在原增强部位形成软化灶。

Enhancement emerged around the operative area in early post operative period shows tendency of gradual reduction or disappearance until malacia appears in the original enhancement area.

术后早期在术区边缘出现的增强，追踪观察有逐渐减弱或消失的趋势，直至在原增强部位形成软化灶。

Enhancement emerged around the operative area in early postoperative period shows tendency of gradual reduction or dis appear ance until malacia appear s in the original enhancement area.

术后早期在术区边缘出现的增强，追踪观察有逐渐减弱或消失的趋势，直至在原增强部位形成软化灶。

Then regular follow-ups by MR were conducted until the malacia appeared or the residual tumor grew again.

以后定期复查，直至软化灶形成或肿瘤复发。

Methods :25 cases of traumatic hydrocephalus were analysed retrospectively.Among them,3 cases showed brain contusion,4 with subrarchnoid hemorrhage,5 with subdural effusion,2 with epidural hematoma,1 with subdural hematoma,1 with fracture of skull,3 with malacia lesions,3 with cerebral infarction,and 2 with cerebral hernia.The other 3 cases were not associated,with intracranial traumatic anomaly.

回顾分析25例外伤性脑积水，其中分别伴颅脑损伤有3例脑挫伤、4例蛛网膜下腔出血、5例硬膜下积液、1例颅骨骨折、3例脑内软化灶、3例脑梗塞、2例硬膜外血肿、1例硬膜下血肿、2例脑疝(大脑镰下疝及钩回疝各1例)，另3例颅内未见外伤性异常改变与其并存。

Results: WTBZ The result s were found:(1) The MRI spinal cord signal of SCI region has basic recovered i n A group and has not recoved completely in B group. There was a malacia focus i n C group.

结果：MRI发现：A组动物，脊髓损伤区脊髓信号已基本恢复正常，B组动物未恢复正常，而C组动物，SCI区有软化灶形成。

The imaging findings of post-trauma dysosmia commonly manifest as malacia and chronic hemorrhageic foci in frontal lobe, olfactory bulbs and tracts as well as temporal lobes.

外伤后嗅觉功能障碍的最常见影像学表现是额叶底部、嗅球嗅束和颞叶的软化灶、陈旧出血改变。

Results Contrast CT or MRI showed prominent irregular circular or nodular enhancement in 14 of 16 cases (64%),can not distinguished from postopertative changes, radioinjury, tumor residue or recurrence.Among them, 9 cases showed tumor residue or recurrence based on significantly increased FDG uptake, 5 were confirmed by pathologic study. The other 5 cases of cerebral necrosis and 2 cases with postoperative cerebral malacia demonstrated FDG uptake defects.

结果 16例中87.5%(14例)CT和MRI表现不规则环形或结节状明显强化，不能准确作出手术后改变和放射治疗后脑损伤、残存肿瘤或肿瘤复发的诊断；其中9例残存肿瘤或肿瘤复发病灶18F-FDG PET影像表现为葡萄糖代谢明显增高，有5例得到手术病理证实；另5例术后放射治疗后脑损伤患者和2例术后软化灶18F-FDG PET影像均显示局部病变区为放射性分布缺损或明显低下。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
