1. Thrombi causing the acute cerebral infarction were detected on noncontrast CT in 40 of the 51 patients and 34 of the 40 received thrombolytic therapy.

51位患者中有41人经上述检查证实为血栓引起的急性脑梗塞，其中34人进行了溶栓治疗。

2. CT noncontrast enhanced scan

CT平扫

3. Noncontrastive CT appearances:Tumors showed mass shadow with clear outline,in which slightly hyperdensity 75%,hypodensity 25%,16 7% of them have calcification;

CT平扫表现为病变呈团状 ,境界清楚 ,其中高密度占 75% ,低密度占 2 5% ,16 7%见有点状钙化 ;

4. Encephalopathic term infants with birth trauma, low hematocrit, or coagulopathy should receive noncontrast CT to detect hemorrhage, which is a major cause of cerebral palsy in term infants.

伴随产伤、低血球容积、或凝血病的脑病足月婴儿应当接受无对照的CT检查，来发现是否有脑出血，这是导致足月婴儿发生脑瘫的一种主要的病因。

5. Using polyethylene tubes to simulate the intracranial arteries, the HU count was measured on noncontrast CT, from which the amount of erythrocytes and platelets within the thrombus was determined.

使用聚乙烯管模拟颅内动脉，用增强CT测定其HU值，可以判断血栓内的红细胞及血小板的数量。

6. FIG 1.A noncontrast CT shows a well circumscribed and rounded high-attenuation area in the left Sylian fissure without clearly defined mass effect.
