Transcatheter CT arterial portography and CT hepatic arteriography for liver tumor visualization during percutaneous ablation.
PURPOSE To evaluate the feasibility of combining transcatheter computed tomography (CT) arterial portography or transcatheter CT hepatic arteriography with percutaneous liver ablation for optimized and repeated tumor exposure. MATERIALS AND METHODS Study participants were 20 patients (13 men and 7 women; mean age, 59.4 y; range, 40-76 y) with unresectable liver-only malignancies--14 with colo...
متن کاملHepatic adenomatous hyperplasia with hyperattenuation on CT during arterial portography: a case report.
We report a 72-year-old man who was admitted to our department with multiple nodules of hepatocellular carcinoma (HCC) in a cirrhotic liver because of HCV infection. Unlike most of the nodules, one in segment 2 (S2) showed hypoattenuation on computed tomography (CT) during hepatic arteriography (CTA), and hyperattenuation on CT during arterial portography (CTAP). Fine needle aspiration biopsy o...
متن کاملEffect of prostaglandin E1 on contrast enhanced CT of the liver: statistical analysis during arterial portography.
PURPOSE To determine the diagnostic effect of prostaglandin E(1) on contrast enhancement quality of CT during arterial portography (CTAP). MATERIALS AND METHODS Our patients population included 30 patients (11 women, 19 men; age range, 41 approximately 81 years) with liver tumors (23 hepatocellular carcinoma and 7 metastatic liver tumor) who had undergone angiography. We divided the 30 patien...
متن کاملHepatic arterial supply in 1297 CT-angiographies.
PURPOSE Analysis, evaluation and classification of hepatic arterial supply variants and determination of their frequency distribution in CT-angiographies. MATERIALS AND METHODS CT-angiographies of 1,568 patients were evaluated retrospectively for the period between January 1, 2010 and August 30, 2012. The hepatic arterial anatomy was assessed and categorized according to Michels's classificat...
متن کاملDetection and Classification of Liver Cancer using CT Images
This paper presents the enhancement of Computed tomography (CT) images using two different algorithms: Contrast Limited Adaptive Histogram Equalization (CLAHE) and Constrained Variable Histogram Equalization (CVHE). CLAHE enhanced the tumor region in a new look. CVHE enhanced with preserving the globalization of an image. The normal liver detection is done by the ox plot comparison in CLAHE. Pr...
