Background: Magnetic resonance signal intensity of focal liver lesions is affected by numerous pathologic factors. Lesion histologic features, such as cellularity, vascularity, stromal component, and intratumoral necrosis or hemorrhage, strongly affect T1 and T2 relaxation times. Aim: Our study is done to assess the lesion characterization potential of MRI by evaluating unenhanced and dynamic g...

Purpose : The present study assess factors affecting the success of US and CT-guided liver biopsy of focal lesions on the basis of experience when cytopathologic examination results were available.Methods and Materials: 175 liver biopsies and punctures in 175 patients(120 male and 55 female) were performed under US or CT control. Lesions ranged in diameter from 9mm to 25 mm. We utilized US guid...

OBJECTIVE To evaluate the concordance between intraoperative ultrasound (IOUS) and abdominal ultrasound (US) for the characterization of focal liver lesions in patients with colorectal cancer, and to evaluate the way in which IOUS influences the initially established hepatic surgical protocol based on abdominal US only. METHOD In this prospective study 73 patients with colorectal cancer and f...

A 30-year-old lady treated with capecitabine for primary colon adenocarcinoma developed liver lesions suspicious for metastasis. Liver biopsies showed sinusoidal dilatation thought to be secondary to capecitabine. This case highlights the importance of differentiating between benign and malignant liver lesions during cancer surveillance preventing unnecessary liver resections for benign disease.

The histopathological effects of Linear Alkylbenzene Sulfonate on the gill, liver and kidney tissues of the Caspian kutum, Rutilus frisii kutum were studied. The fish were exposed to three sublethal concentrations of anionic detergent, Linear Alkylbenzene Sulfonate (LAS) for short term intervals (192 h). Gill, liver and kidney samples were collected after 192 h of exposure to LAS and lesions we...

metastases are the most common malignant hepatic lesions and considered to be the most frequent indication for imaging of the liver. the accurate detection and characterization of liver metastasis remains a critical issue at the initial diagnosis of primary cancer or during the course of patient treatment. in the recent years, the advent of highly efficient imaging modalities and new techniques...

•The DLIR demonstrated a significant noise reduction and improved image quality. could be used as surrogate for the IR method. •Higher strength of was possible to decrease lesion conspicuity. AIM To evaluate use deep-learning-based reconstruction (DLIR) algorithms in dynamic contrast-enhanced computed tomography (CT) abdomen, compare quality conspicuity among levels. MATERIALS AND METHODS This ...

Liver adenomatosis is defined by the presence of multiple hepatic adenomas (more than three lesions). The natural history and treatment of liver adenomatosis are not yet well defined. The Mayo Clinic (Rochester, MN) experience with liver adenomatosis in the past 11 years was reviewed and a rational treatment approach is presented. Records from patients with liver adenomatosis and hepatic adenom...

Frequent gains of 20q have been identified recently in many neoplasias, including breast, bladder, ovarian, pancreatic, and colon cancers. A high level of 20q13.2 amplification is associated with poor prognosis in breast cancer. We investigated the copy number of the 20q13.2 region including the ZNF217 oncogene in 17 nonmetastatic colorectal cancers (CRCs), 18 primary CRC tumors with liver meta...
