Abstract:
Objective To investigate the sensitivity difference between CT angiography (CTA)and MR angiography (MRA)in detecting portal hypertension,and explore the diagnostic value of the two methods for portal hypertension.Methods The imaging data of portal hypertension patients who were diagnosed by surgical exploration or vascular intervention in our hospital were collected,the accuracy and sensitivity of CTA and MRA in portal hypertension diagnosis were analyzed.Results A total of 351 portal hypertension patients were included in our study,prehepatic portal hypertension were 89 cases,intrahepatic portal hypertension were 121 cases,posterior portal hypertension were 131 cases.The detective cases about prehepatic portal hypertension,intrahepatic portal hypertension and posterior portal hypertension in MRA group were 85 cases,101 cases and 97 cases,in CTA were 79 cases,120 cases and 128 cases. The portal hypertension detection rate of CTA was 93.16%,there was significant difference with surgical exploration or interventional angiography (P1,3＜0.000 1＜0.05).The portal hypertension detection rate of MRA was 80.63%,there was significant difference with surgical exploration or interventional angiography (P1,2＜0.000 1＜0.05),the differences between MRA and CTA was significant (P2,3＜0.000 1＜0.05). Conclusion The sensitivity of CTA is much higher than MRA,which is a non-invasive examination,and worthy of clinical promotion.
