Diagnostic validity and reliability of BT-RADS in the management of recurrent high-grade glioma.

Background And Purpose: BT-RADS is a new framework system for reporting the treatment response of brain tumors. The aim of the study was to assess the diagnostic performance and reliability of the BT-RADS in predicting the recurrence of high-grade glioma (HGG).

Materials And Methods: This prospective single-center study recruited 81 cases with previously operated and pathologically proven HGG.

Diagnostic accuracy of dual-energy computed tomography in the diagnosis of neurological complications after endovascular treatment of acute ischaemic stroke: a systematic review and meta-analysis.

Objectives: To investigate dual-energy computed tomography's (DECT) diagnostic performance in detecting neurological complications following endovascular therapy (EVT) of acute ischaemic stroke (AIS).

Methods: We performed the literature search using Web of Science, Scopus, PubMed, EBSCO, and Science Direct databases for published related studies. The selected studies estimated the validity of DECT in the detection of neurological complications after EVT for AIS.

Validation of Coronary Artery Disease Reporting and Data System (CAD-RADS) and Application of Coronary Artery Calcium Data and Reporting System (CAC-DRS) as New Standardized Tools in the Management of Coronary Artery Disease Patients.

Background And Objectives: The coronary artery disease reporting and data system (CAD-RADS) is intended to standardize the reporting of CCTA and the subsequent management guidelines of CAD. The present study was conducted to investigate the validation of CAD-RADS and the application of coronary calcium grading in CAD management.

Patients And Methods: The current study is a single-center prospective study that involved 177 participants with chest pain who were submitted to coronary CT angiography (CCTA).

Combined therapy with conventional trans-arterial chemoembolization (cTACE) and microwave ablation (MWA) for hepatocellular carcinoma >3-<5 cm.

Purpose: To compare safety and efficacy of combined therapy with conventional transarterial chemoembolization (cTACE)+microwave ablation (MWA) versus only TACE or MWA for treatment of hepatocellular carcinoma (HCC) >3-<5 cm.

Methods: This randomized controlled trial (NCT04721470) screened 278 patients with HCC >3-<5 cm. Patients were randomized into three groups: 90 underwent TACE (Group 1); 95 underwent MWA (Group 2); and 93 underwent combined therapy (Group 3).

Brain magnetic resonance spectroscopy (MRS) as a diagnostic tool for detecting early neurological changes in children with Wilson's disease.

Purpose: Although brain magnetic resonance spectroscopy (MRS) imaging findings in adult Wilson disease (WD) have been explained in extensive details, a paucity of information currently exists regarding brain MRS imaging findings in pediatric WD. The purpose of this study was to clarify the role of brain MRS in detecting early metabolite abnormalities in children with WD.

Patient And Methods: A case-controlled prospective study included 26 children with WD and 26 healthy controls.

The utility of diffusion-weighted imaging in improving the sensitivity of LI-RADS classification of small hepatic observations suspected of malignancy.

Purpose: We investigated the added value of diffusion-weighted imaging (DWI)/apparent diffusion coefficient (ADC) in the categorization of small hepatic observation (≤ 20 mm) detected in patients with chronic liver disease in reference to LI-RADS (liver imaging reporting and data system) classification system.

Methods: We prospectively evaluated 165 patients with chronic liver disease with small hepatic observations (≤ 20 mm) which were previously categorized as LI-RADS grade 3-5 on dynamic contrast-enhanced CT (DCE-CT). All patients were submitted to a functional MRI including DCE and DWI.

The Predictive Value of Multidetector High Resolution Computed Tomography in Evaluation of Suspected Sputum Smear Negative Active Pulmonary Tuberculosis in Egyptian Zagazig University Hospital Patients.

The aim of this work is to study the usage of multi-detector HRCT chest in diagnosing pulmonary TB cases whose sputum smears are negative and making a correlation between their CT features and their sputum culture results. This study was carried out from December 2014 to December 2016 at Zagazig university hospitals, Radiodiagnosis department. It included 150 patients.

Diagnostic Performance of Multidetector Computed Tomography (MDCT) in Diagnosis of Sinus Variations.

Background: In this prospective study, we looked for correlations between anatomic variants of paranasal sinuses and chronic or recurrent sinusitis.

Material/methods: Two hundred and forty (240) patients with clinical features of chronic rhinosinusitis were examined; patients with first-onset or allergic sinusitis and pregnant females were excluded. Routine multi-slice CT of the paranasal sinuses was performed to look for mucosal disease of the paranasal sinuses, drainage pathways, and presence of anatomical variations and their relation to known sinus drainage pathways.

Multidetector Computed Tomography (CT) in Evaluation of Congenital Cyanotic Heart Diseases.

Background: The aim of the study is to emphasize the role of 128 MSCT angiography in the diagnosis of congenital cyanotic heart diseases.

Material/methods: This study included sixty patients and was conducted from December 2014 to July 2016 in the Multidetector CT unit of Zagazig University hospitals. All images included axial, MPR, MIP, and VRT and were interpreted in one session.
