Implementation of a web-based, interactive polytrauma tutorial in computed tomography for radiology residents: how we do it.

Purpose: Due to the time factor in polytraumatized patients all relevant pathologies in a polytrauma computed tomography (CT) scan have to be read and communicated very quickly. During radiology residency acquisition of effective reading schemes based on typical polytrauma pathologies is very important. Thus, an online tutorial for the structured diagnosis of polytrauma CT was developed.

Imaging of the brain in polytraumatized patients comparing 64-row spiral CT with incremental (sequential) CT.

Introduction: Up to now, due to a better image quality, for brain imaging the substantially slower sequential examination mode has been preferred during CT in polytraumatized patients. We aimed to re-evaluate modern ultrafast 64-row spiral CT regarding image quality in brain imaging of polytraumatized patients.

Methods: In 30 polytraumatized patients, both 64-row spiral and sequential CT of the brain were performed within 24h.

Chronic thromboembolic pulmonary hypertension: evaluation with 64-detector row CT versus digital substraction angiography.

The aim of the study was to evaluate the role of 64-row CT in the diagnostic workup of patients with chronic thromboembolic pulmonary hypertension (CTEPH) using digital substraction angiography (DSA) as the method of diagnostic reference. CT and DSA studies of 27 patients (54 main, 162 lobar and 540 segmental arteries) with a clinical suspicion of CTEPH were included in this retrospective and blinded analysis. Axial images and multiplanar thin maximum intensity projections (MIPs) (3mm) were consequently used for exact image interpretation whereas additional reconstructed thick MIPs gave an overview of the entire vascular tree comparable to DSA.
