Role of CT angiography in detecting acute pulmonary embolism associated with COVID-19 pneumonia.

Purpose: Recently coronavirus disease (COVID-19) caused a global pandemic, characterized by acute respiratory distress syndrome (ARDS). The aim of our study was to detect pulmonary embolism (PE) in patients with severe form of COVID-19 infection using pulmonary CT angiography, and its associations with clinical and laboratory parameters.

Methods: From March to December 2020, we performed a prospective monocentric study collecting data from 374 consecutive patients with confirmed SARS-CoV-2 infection, using real-time reverse-transcriptase polymerase-chain-reaction (rRT-PCR) assay of nasopharyngeal swab specimens.

An unusual case of congenital mesocolic hernia.

An internal hernia is defined as the herniation of viscera through an anatomic or pathologic opening within the confines of the peritoneal cavity. This herniation may be persistent or intermittent. Because of the risk of strangulation of the hernia contents, even small internal hernias are dangerous and may be lethal.

[The solitary pulmonary nodule: the preliminary results in differential diagnosis by high-resolution computed tomography with a contrast medium].

Introduction: High-resolution computed tomography (HRCT) with iodinated contrast material has been used by many authors to study solitary pulmonary nodules (SPNs). The degree of enhancement was correlated with the nodule malignancy.

Material And Methods: Forty adult patients were examined, before and after contrast agent administration, with incremental dynamic CT.
