Characterization of Hepatocellular Carcinoma Using CT Intensity and K-means

The aim of this study was to characterize the hepatocellular carcinoma HCC CT intensity relative to normal liver tissue and other abdominal organs kidney, pancreas and stomach. The method used was the texture analysis which is depends on the collection of CT Number in Hounsfield Unit as excerpted from the k-means technique and the CT system used was tri-phases multidetector computerized tomography MDCT. The analyzed data showed that the detected mean size of HCC lesions was 11.25.3 cm2. And the mean intensity in HU of the selected abdominal classes i. e. HCC, liver, kidney, spleen and stomach were (111, 146, 137), (128, 172.1, 158), (172, 221, 207.6), (142, 188, 174), (151, 196, 182.7) during plain, arterial and venous phases respectively. While the ultimate golden scored was the intensity % of HCC relative to normal liver, kidney, spleen and stomach through the different imaging phases (plain, arterial and venous), were 1 %, 26 %, 83 %, 42 % and 80 % respectively.
