螺旋CT在腕舟骨骨折诊断中的临床价值

目的探讨螺旋CT(SCT)在腕舟骨骨折诊断中的临床应用价值。方法 60例早期腕舟骨骨折患者经腕关节常规X线检查后,采用SCT进行腕关节的螺旋扫描,并在工作站上作多平面重建(MPR)及表面遮盖显示(SSD)影像后处理。60例舟骨骨折病例均按Herbert分型,并对X线平片与螺旋CT影像进行比较及综合分析。结果 60例舟骨骨折病例中,A1型4例(6.6%),A2型5例(8.3%),B1型2例(3.3%),B2型29例(48.3%),B3型15例(25%),B4型5例(8.3%),X线平片漏诊12例,此12例X线平片漏诊的骨折均经螺旋CT确诊。结论螺旋CT能够明确腕舟骨骨折的诊断,多能清晰显示X线平片难以诊断的腕舟骨隐匿性骨折;SSD和MPR成像技术能立体直观观察腕舟骨的骨折线走行及移位情况,能对腕舟骨骨折作出准确的分型,从而为临床治疗方案的拟定提供重要参考。

Application of spiral CT in diagnosing scaphoid fractures

Objective To evaluate the value of CT scanning in the diagnosis of acute pancreatitis(AP).Methods Thirty-two patients with AP proved clinically underwent CT plain scan of abdomen,contrast enhanced CT scans were performed on 6 of them in addtion.CT findings of all patients were retrospectively analyzed.Results The study demonstrated that there were 19 mild AP and 13 severe AP in the group.Lesions mainly appeared as diffuse swelling of pancreas associated with density decreasing.The irregular hypodense zones were found in 9 cases,the peripancreatic effusion in 17 cases and the localized mottling hemorrhagic shadows with hyperdensity in 1 case.Conclusion CT scan is an important method for diagnosis of AP and its complications.
