OBJECTIVE To assess the diagnostic accuracy of triphasic spiral CT in differentiating benign from malignant focal tumoral liver lesions. METHODS The study was conducted in Department of Radiology of Aga Khan University Hospital and Sind Institute of Urology and Transplantation, Karachi from Feb 2006 to Feb 2007. By convenient sampling, 45 patients found to have focal tumoral liver lesions wer...

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...

Liver masses present a relatively common clinical dilemma, particularly with the increasing use of various imaging modalities in the diagnosis of abdominal and other symptoms. The accurate and reliable determination of the nature of the liver mass is critical, not only to reassure individuals with benign lesions but also, and perhaps more importantly, to ensure that malignant lesions are diagno...

Objective: To compare superparamagnetic iron oxide-enhanced magnetic resonance imaging with 5-phase computed tomography in the detection and characterisation of focal liver lesions. Patients and Methods: We prospectively performed 5-phase computed tomography scans followed by magnetic resonance imaging of the liver with superparamagnetic iron oxide magnetic resonance contrast medium in patients...

The introduction of microbubble contrast agents and the development of contrast-specific techniques have opened new possibilities in liver imaging. Initially, only intermittent imaging with Doppler detection was available. Second-generation contrast agents and low mechanical index real-time scanning techniques are decisive advances that enable convenient liver examinations with high sensitivity...

during all recorded phases compared to the surrounding splenic tissue. Due to the fact that lymphoma involvement of the liver usually does not present a hyperechoic pattern in B-mode and that the contrast-enhanced examination indicated malignant lesions, we performed a biopsy of one of the liver masses using a 18-gauge needle with a throw of 33 mm. Differential diagnosis of hyperechoic liver le...
