A Study On Diagnosis Value Of MRCP For Biliopancreatic Obstruction Disease

Objective:To analyze the MRCP features of obstructive jaundice,and explore clinical application value of MRCP combining conventional MRI plain-scan and enhancement examination.Materials and Methods 168 patients with obstructive jaundice were retrospective analyzed from March 2010-January 2012,benign obstruction in 115 cases,including the bile duct inflammatory stenosis in 20,95 cases of bile duct;Malignant obstruction in 53,including bile duct carcinoma in 15 cases,pot belly 26 cases of cancer,the cancer of the head of pancreas 12 cases,preoperative routinely offer MRCP combine MRI plain-scan and strengthen and examination,preoperative examination results and postoperative pathological results are compared.Results:1.115 cases of benign obstruction image quality in addition to 90.43%(104/115),malignant obstruction image quality in addition to 52.83%(28/53),two more,the difference was statistically significant(the chi-square = 30.4711,P<0.01).2.168 patients positioning qualitative diagnosis analysis,the MRCP qualitative diagnosis accuracy rate was 91.67%(154/168),its location accuracy rate is 95.83%(161/168),MRCP combine conventional MRI plain-scan and qualitative diagnosis accuracy+ increase was 96.73%(163/168),its location accuracy rate is 97.52%(164/168),and surgical results are in agreement.3.bilibpancreatic obstruction to the parts of the classification.Obstruction of the pancreatic head area with benign pancreatic head area and see more,both accounted for 65.22%(75/115),malignant obstruction to duodenal nipple area most accounted for 49.05%(26/53).Biliopancreatic obstruction expansion degree,benign expansion to mild primarily,malignant expansion to severe primarily,compare two groups,the difference was statistically significant(P<0.01).4.benign obstruction to dead branches,give priority to,malignant obstruction to soft vines primarily."Four tube levy" is the specificity of the head of pancreas cancer diagnosis signs.Conclusion:MRCP is a kind of post-interventional and noninvasive imaging technology of obstructive jaundice,its clinical application value enhances unceasingly.According to the expansion and interrupt site of the bile duct,it can be accurately made a position diagnosis of lesions,and according to the lesions position,the expansive degree and the shape of biliopancreatic duct,the form of the obstruction and the details of’ lesions,it can be accurately made qualitative diagnosis,and further more,analyze the causes and quantitative measurement of obstructive jaundice.MRCP as noninvasive examination technology,play an important role for increasing the diagnostic accuracy rate of obstructive jaundice disease.To combine conventional MRI plain-scan and enhancement examination,It can improve the location and qualitative diagnostic accuracy of obstructive jaundice disease.
