MRI和CT影像学检查对肝脏疾病术前诊断及术后恢复的评估
|
摘要
目的:探析磁共振成像(MRI)和X射线计算机断层扫描(CT)影像学检查在肝脏疾病患者术前诊断及术后恢复情况评估的价值。方法:回顾性分析60例手术前后均接受CT和MRI影像学检查的肝脏疾病患者;比较MRI和CT两种不同影像学检查技术的诊断符合率、影像学特征以及术后恢复情况。结果:MRI检查对肝内和肝外病灶的检出数均显著优于CT检查,其差异有统计学意义(t=5.628,t=6.539;P<0.005);MRI检查对肝内和肝外病灶的阳性率均显著优于CT检查,其差异有统计学意义(x~2=8.015,x~2=6.652;P<0.010)。经对60例患者术后MRI和CT复查,MRI和CT肝脏疾病诊断准确率分别为96.61%和67.80%,MRI诊断准确率显著高于CT,差异具有统计学意义(x~2=16.741,P<0.05)。结论:相对于CT检查,MRI对临床肝脏疾病患者的术前诊断以及术后疗效评价均具有更为明显的优势。
Objective: To explore the value of imaging examinations of magnetic resonance imaging(MRI) and X-ray computed tomography(CT) in preoperative diagnosis and postoperative recovery of patients with hepatic diseases. Methods: A retrospective analysis of 60 patients with hepatic disease who underwent examinations of CT and MRI before and after surgery was performed. The diagnostic coincidence rate, imaging characteristics and postoperative recovery of two different imaging examination techniques, MRI and CT, were compared. Results: The detectable amount of intrahepatic and extrahepatic lesion of MRI examination was significantly better than that of CT examination(t=5.628, t=6.539, P<0.005). The positive rates of intrahepatic and extrahepatic lesion of MRI examination were significantly better than that of CT examination(x~2=8.015, x~2=6.652, P<0.010), respectively. The results of 60 patients post operative reexamination of MRI and CT indicated that the diagnostic accuracy rate of MRI examination(96.61%) was significantly higher than that of CT examination(67.80%)(x~2=16.741, P<0.05).Conclusion: Compared with CT examination, MRI examination has more obvious advantage for clinical patients with hepatic disease in preoperative diagnosis and postoperative evaluation.
