IDENTIFICATION OF DIFFERENT LIVER DISEASES BY USING IMAGERY TECHNIQUES: A REVIEW.

The aim of this study is to characterize the different liver diseases which are related to infect liver tissue and other infected part like spleen, pancreas, and stomach. The methods used are preprocessing ,segmentation, feature extraction, texture analysis which is depend upon the collection of Computed Tomography(CT) scans, MRI(Magnetic Resonance Imaging) and Ultrasounds(US) of different patient collected from the hospitals. MRI is playing an important role in analyzing the liver disease patients due to its high soft tissue resolution, lack of ionizing radiation and ability to provide functional data. Imaging techniques like ultrasonography, CT scans, MRI are used to get the enhanced image of infected part of liver so that can easily characterized and detect the particular disease in liver patient. Diffusion Weighted Imaging (DWI) is used to identify the lesion in the liver and Perfusion Weighted Imaging (PWI) is used to identify the volume and functioning of the cirrhotic liver.
