Efficacy and Safety of Microwave Ablation (MWA) for Hepatocellular Carcinoma (HCC) in Difficult Anatomical Sites in Egyptian Patients with Liver Cirrhosis.

Background and aim: Imaging guided microwave ablation (MWA) for hepatocellular carcinoma (HCC) has become a widely used method over recent years. Tumors close to the diaphragm, gastrointestinal tract, gallbladder, pancreas, hepatic hilum and major bile duct or vessels are generally considered relative contraindications for microwave ablation. This study was conducted to assess the effectiveness and safety of ultrasonography-guided MWA in treating patients with HCC in difficult anatomical sites in comparison to those in conventional sites.

Utility of point shear wave elastography in characterisation of focal liver lesions.

Background: The present study aimed at evaluation of the usefulness of point shear wave elastography (pSWE) in characterization of FLL(s) by quantifying their stiffness.

Methods: In total, 197 patients (mean age was 56.57 years) with FLL(s) on conventional ultrasound were included.

Differentiation of benign and malignant bowel lesions by transabdominal ultrasound using grey-scale and Doppler parameters.

Background And Study Aims: The aim of this study was to assess the ability of transabdominal ultrasonographic morphologic features and Doppler flow parameters in differentiating benign from malignant bowel lesions.

Patients And Methods: Sixty patients with sonographically detected gastrointestinal lesions and 30 control subjects were prospectively enrolled. Bowel wall thickness; length of the affected segment; the wall layering pattern; the resistive index (RI); pulsatility index (PI); flow volume (FV) of the intramural vessels, the superior mesenteric artery (SMA), and the portal vein (PV) were recorded.

Role of peritoneal ultrasonography and ultrasound-guided fine needle aspiration cytology/biopsy of extravisceral masses in the diagnosis of ascites of undetermined origin.

Background And Study Aims: Ascites may be of undetermined origin despite comprehensive study. This study aimed to assess the accuracy and safety of conventional and interventional high-frequency peritoneal ultrasound in the diagnosis of patients with ascites of unclear origin.

Patients And Methods: A total of 62 patients were prospectively enrolled; they underwent conventional (3.
