CT Diagnosis of Primary Liver Cancer(100 Analysis Enclosed)
Objective To explore the diagnostic value of liver spiral-enhanced CT for primary liver carcinoma(PLC).Methods A total of 100 patients with PLC were enrolled as the research objects between June 2018 and September 2020.The clinical pathology,surgical and imaging data of patients were collected.Taking the results of pathological examination as the golden standard,all underwent CT plain scan and spiral-enhanced CT scan.The diagnostic value of the two methods for PLC was compared,and the relationship between CT value and micro-vascular invasion after enhancement was explored.Results The detection rate and accurate detection rate of spiral-enhanced CT scan for PLC were higher than those of CT plain scan(96.00%vs 75.00%,x2=17.786,P<0.05;87.00%vs 69.00%,x2=9.441,P<0.05).There were 126 round or quasi-circular lesions detected out in this study,including 17 lesions in left lateral lobe of liver,22 lesions in left medial lobe of liver,21 lesions in right anterior lobe of liver and 66 lesions in right posterior lobe of liver.The high-density uniform enhancement was in the majority during hepatic arterial phase,and enhancement was gradually weakened during portal vein and delayed phases.CT value during portal vein phase in micro-vascular invasion group was greater than that in non-micro-vascular invasion group(82.93±11.94)HU vs(70.25±11.43)HU,t=5.426,P<0.05).There was no significant difference in CT values during arterial and delayed phases between the two groups(P>0.05).Conclusion The liver spiral-enhanced CT can clearly display the characteristics of PLC,which is of great value for improving the detection rate and qualitative accuracy rates of liver carcinoma.
