Diagnostic accuracy of CT enterography correlated to histopathology in the diagnosis of small bowel Crohn's disease.

Background: Crohn's disease (CD) is a chronic inflammatory process affecting the gastrointestinal tract, mainly the terminal ileum of small bowel. Although ileocolonoscopy provides good mucosal visualization, it does not allow evaluation of extraluminal abnormalities. Computed tomographic enterography (CTE) is an emerging imaging modality for assessment of small bowel disorders.

The diagnostic accuracy of coronary computed tomography angiography in patients with and without previous coronary interventions.

Background: Invasive coronary angiography (ICA) is the gold standard for imaging coronary arteries and the severity of coronary artery disease (CAD). Coronary computed tomography angiography (CCTA) has undergone remarkable progress in the diagnosis of CAD.

Objectives: To evaluate the effect of prior vs no previous coronary interventions on the diagnostic accuracy of CCTA as an alternative to ICA to improve health outcomes for patients with suspected CAD.

Efficiency of High and Standard Value Diffusion-Weighted Magnetic Resonance Imaging in Grading of Gliomas.

Background: Glioma is the most common fatal malignant tumor of the CNS. Early detection of glioma grades based on diffusion-weighted imaging (DWI) properties is considered one of the most recent noninvasive promising tools in the assessment of glioma grade and could be helpful in monitoring patient prognosis and response to therapy.

Aim: This study aimed to investigate the accuracy of DWI at both standard and high values ( = 1000 s/mm and  = 3000 s/mm) to distinguish high-grade glioma (HGG) from low-grade glioma (LGG) in clinical practice based on histopathological results.
