作者用GE9800型CT扫描机为37例腹部钝伤所致脾损伤非手术治疗的儿童(男26例,女11例,年龄12个月～16岁)在伤后2周～11个月时做CT随访。全部病人均做增强扫描,其中28例在增强前还做了平扫。扫描层厚10mm,间隔10mm,范围包括腹部及盆腔。增强采用经静脉手动团注法注入造影剂。由两位放射学专家评阅病人原始CT片和随访CT片,并根据Mirvis等以前的修改体制对原始片中脾损伤程度做出意见一致的分级。Ⅰ度伤,指脾浅表性裂伤或者被膜下血肿(直径<1cm)。Ⅱ度伤,即脾实质裂伤,深1～3cm,或伴中央或被膜下血肿(直径<
The authors used GE9800 CT scanner for 37 cases of non-surgical treatment of splenic injury caused by abdominal blunt trauma (26 males and 11 females, aged 12 months to 16 years) at 2 weeks to 11 months after injury CT follow-up. All patients underwent enhanced scan, of which 28 cases were enhanced before the scan. Scanning layer thickness 10mm, interval 10mm, the scope includes the abdomen and pelvis. Enhance the use of intravenous bolus injection of contrast agent. Two radiologists reviewed the patient’s original CT scan and follow-up CT scan, and made a consistent rating on the degree of splenic injury in the original patch according to the previous revision of Mirvis et al. Ⅰ degree of injury, refers to superficial spleen laceration or subcapsular hematoma (diameter <1cm). Ⅱ degree of injury, that spleen substantive laceration, deep 1 ~ 3cm, or with central or subependymal hematoma (diameter <
