Abstract
This study describes a new liver segmentation method for purpose of transplantation surgery as a treatment for liver tumors. Liver segmentation is not only the key process for volume computation but also fundamental for further processing to get more anatomy information for individual patient. Due to the low contrast, blurred edges, large variability in shape and complex context with clutter features surrounding the liver that characterize the liver CT images, it is a convoluted problem and still a challenge task to robustly and accurately segment the liver. In this paper, we overcome these difficulties with a novel variational model based on the idea of intensity probability distribution propagation and region appearance propagation with which we can focus on the target liver regardless of how complex the uninterested background is. This segmentation is based on combining a modified k-means segmentation method with a special localized contouring algorithm. In the segmentation process in order to divide the image, five separate regions are identified on the computerized tomography image frames. The merit of the proposed method lays in its potential to provide fast and accurate liver segmentation and 3-D rendering as well as in delineating tumor region(s), all with minimal user interaction

Liver imaging in patients with a history of known or suspected malignancy is important because the liver is a common site of metastatic dissemination, especially colon, lung, pancreas and stomach tumors, and in patients with chronic liver disease who are at risk of developing Hepatocellular carcinoma. Since benign liver lesions are common, liver imaging strategies should incorporate the detection and characterization of liver lesions. Examination of the survey in patients with known extrahepatic malignancy to exclude the presence of hepatic and extrahepatic involvement is usually performed with an improved contrast computed tomography (CT) scan. When patients with liver metastases are being considered for metastasis, they undergo an enhanced contrast magnetic resonance imaging (MRI) staging test using tissue-specific contrast agents. Patients with chronic liver disease who are at risk of hepatocellular carcinoma undergo periodic liver exams for focal liver detection, usually with ultrasound (US) with MRI used when the US Is equivocal. Finally, contrast MR with extracellular gadolinium chelates is preferred for the characterization of indeterminate hepatic masses with liver biopsy used when tissue diagnosis is required.
For the detection and characterization of suspected primary or secondary tumors, images of the liver are performed prior to planning for placement of a chemotherapy or surgical pump for assessment of response to treatment, assessment of biliary disease, and detection of neoplasms In high-risk groups. In this article, we review the advantages and disadvantages of various imaging modalities in liver evaluation and formulate guidelines for imaging common clinical indications. A brief review of imaging findings in focal and diffuse liver disease is also presented.
The liver is an important organ from an oncological perspective. Primary hepatic neoplasms are common, especially in the presence of diffuse liver disease, such as cirrhosis, hemochromatosis and steatohepatitis. The liver is the most common site of metastasis of gastrointestinal tumors. Elevated blood flow (about 25% of cardiac output), favorable microscopic anatomy (hepatic and empty sinusoids in the subendothelial basement membrane) and a rich biochemical environment favor the rapid growth of metastatic deposits in the liver. The objectives of the hepatic image in oncology are the detection of liver disease, characterization of liver lesions, staging of neoplasms, evaluation of biliary ductal status, assessment of response to treatment and evaluation of vascular anatomy for Surgical planning and chemotherapy Placement of the pump. It is important to understand the usefulness of different imaging modalities to optimally address the clinical issue at hand.
