多层螺旋CT与核磁共振成像在细微及隐匿性骨折中的诊断价值

Diagnostic value of MSCT and MRI in microscopic and occult fracture

目的探讨多层螺旋CT(MSCT)与核磁共振成像(MRI)检查在诊断细微及隐匿性骨折中的阳性率和特异性,对比分析两种检查方法诊断细微及隐匿性骨折的价值。方法回顾性分析湖北医药学院附属东方医院诊断的细微及隐匿性骨折150例,分析MSCT、MRI、X线检测骨折部位,计算总检出数及阳性检出率,对比分析MSCT、MRI诊断细微及隐匿性骨折的优势和特异性。结果 MSCT诊断骨折125例,阳性检出率83.33%。同时经MRI检查,T1WI检出骨折141例,阳性检出率94.00%,T2WI骨折检出率100.00%。MSCT与MRI对细微及隐匿性骨折阳性检出率差异有统计学意义(P<0.05)。结论 MRI在骨挫伤中显影率高,不同扫描参数可对比得出骨折数据,尤其适用于隐匿性骨折及合并血肿、脂肪覆盖等骨折情况复杂的患者。

Objective To explore the positive rate and specificity of multi-slice CT（MSCT） and magnetic reso-nance imaging（MRI） technology in the diagnosis of microscopic and occult fracture patients ,compared the diagnosis value in fracture patients of these two different kinds of examination methods .Methods One hundred and fifty cases with suspected fracture were analyzed retrospectively ,MSCT and MRI ,X-ray were used respectively to detect frac-ture ,calculated for total inspection results and positive detection rate ,compared the respective advantages and speci-ficity of two inspection technology in the diagnosis of microscopic and occult fracturer .Results There were 125 frac-ture patients detected by MSCT examination ,the positive detection rate was 83 .33% .One hundred and fifty cases were detected by MRI examination at the same time ,T1WI see scan imaging was clear ,141 cases of fracture of posi-tive detection rate was 94 .00% ,T2WI fracture imaging rate was 100 .00% .Difference between MSCT and MRI in positive diagnosis rate of detecting occult fracture was statistically significant .Conclusion The positive rate of MRI in bone contusion is high ,different scan parameters can be campared to obtain data of fracture ,MRI is especially suit-able for occult fracture patients with merger hematoma ,fat covering parts .
