Abstract:
Objective To explore the application value of CT value histogram in differential diagnosis between primary hepatoma and other space-occupying lesions in liver.Methods From 2012 to 2013,the imaging data in 243 patients with different isolated space-occupying lesions in liver were analyzed retrospectively who underwent both enhanced and unenhanced abdominal CT scans. The lesions were confirmed as hepatic cyst,hepatic hemangioma or primary hepatoma by pathological and other clinical proofs and divided into 3 groups.The histograms of plain scan and post-contrast triphases were drawn respectively using an attached picture-making software.Relevant data of the histograms were analyzed and compared using the SPSS among three groups.Results The CT value histograms of hepatic cysts,hemangiomas and majority of hepatomas presented normal distribution curves.Negative skewness distribution curve was showed in the tumor within necrosis and liquefaction,whereas the positive curve was showed in hepatoma with more calcification.Some significant differences in the Mean,SD,Max,Min,and R values were confirmed.Conclusion Skew-ness distribution curve has a relative high specificity in diagnosis of primary hepatoma.Both dramatic decrease of the Mean value in delayed phase and obvious increase of the R value in plain scan suggest the possibility of primary hepatoma.
