Abstract
The liver which is a common site of metastatic disease has prompted the researches to select it as the organ most often studied in the truncal body with recent advanced techniques. Computed tomography has become established as the imaging method of choice for routine screening of the liver. This study of density variations in computed tomographic images of the liver was done on sixty patients in the department of anatomy and the department of radiology, Stanley Medical College, Chennai. The study was done by two methods. 1. Non contrast study, 2. Contrast study. The fluctuations of the CT images of the liver were observed as • Focal decreased attenuation masses. • Hyper enhancing focal liver lesions on contrast enhanced computed tomography and • Generalized abnormal attenuation of the liver. The following disease entities with different density range was observed in this study. • Liver cyst - simple cyst. • Liver abscess. • Multiple abscesses. • Hydatid cyst. • Cirrhosis. • Hemangioendothelioma. • Hepatocellular carcinoma – solitary. • Multicentric hepatocellular carcinoma. • Secondaries liver – Hypodense. • Hyperdense secondaries liver. • Cholangiocarcinoma. • Normal anatomy.56 Seventeen cases were observed with normal anatomy of the liver. Diseases like hypodense secondaries, solitary hepatocellular carcinoma, liver abscess and cirrhosis of the liver were observed in majority of the patients. One rare case of hemangioendothelioma was observed in a six year old child, one case of cholangiocarcinoma was also observed. These observations of the density of the liver in CT is of much value to the surgeons in planning an accurate and conservative surgery. CT techniques to evaluate the liver have advanced during the past decade and continues to evolve. We now have a better definition of when and how to utilize these examination to review liver anatomy and disease processes for prompt diagnosis and treatment.
