ABSTRACT
Objective To describe the diagnosis and preoperation evaluation of pancreatic carcinoma with spiral CT three-phase contrastenhanced scan and post-processing.Methods Three-phase helical CT enhanced scan and post-processing images of 41 patients with pancreatic carcinoma were retrospectively analyzed,including the location,size,characteristic of tumor and peripancreatic blood vessels,the results were compared with that of surgery.Results Low degree of enhancement of pancreatic carcinoma in pancreatic phase was showed compared with parenchymal phase.There was significant difference in density between focus and normal pancreas,the lesions were showed clearly.In comparison with surgical results,the diagnostic accuracy of CT was 80.7% and the accurate rate in evaluating the metastasis was 75.8%.Conclusion Three-phase helical CT enhanced scan and postprocessing are of great value in diagnosis of pancreatic carcinoma and it is helpful in choosing the treatment program preoperatively and assessing the respectability of tumors.
ABSTRACT
Objective To study the relationship between anticardiolipin antibody(ACA) and cerebral infarction(CI).Methods The positive rate of serum ACA were determined by enzyme linked immunosorbent assay(ELISA) in 137 patients with CI at first day,first,second,third and fourth week after the onset of the disease.The results were compared with transient ischemia attach(TIA) group,intracerebral hemorrhage(ICH) group and normal control group.Results The positive rate of ACA in CI group(64.9%) was significantly higher than TIA group(24.6%),ICH group(33.6%) and normal control group(17.6%)(all(P
