PET/MR versus PET/CT for locoregional staging of oropharyngeal squamous cell cancer.

Background: The value of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for TN staging in head and neck cancer (HNC) has been proven in numerous studies. A few studies have investigated the value of FDG-PET/magnetic resonance imaging (MRI) in the staging of HNC; the combined results indicate potential for FDG-PET/MRI, but the scientific evidence remains weak.

Purpose: To compare performance of FDG-PET/CT and FDG-PET/MRI for locoregional staging in patients with oropharyngeal carcinomas.

Diagnostic Accuracy of InitiaI Chest X-Rays in Thorax Trauma.

Objective: To evaluate the efficacy, sensitivity and specificity of chest x-ray as a diagnostic imaging tool in management of thorax traumas.

A rare congenital liver anomaly: Hypoplasia of left hepatic lobe.

Morphologic anomalies of liver, as opposed to many other visceral organs, are very rare. Hypoplasia or agenesis of left lobe of the liver is defined as the absence of liver tissue on the left side of liver without previous disease or surgery. It is usually an incidental finding revealed by imaging exams or during abdominal surgery.

Cervicothoracolumbar spinal epidural abscess and cerebral salt wasting.

Background Context: Spinal epidural abscess (SEA) is a rare infectious disease. However, if left unrecognized and untreated, the clinical outcome of SEA can be devastating.

Purpose: To report a rare clinical presentation of a cervicothoracolumbar SEA with cerebral salt wasting (CSW).
