Influence of contrast material density and kV setting on detectability of calcified plaques on coronary CT angiography.

Purpose: To analyze the impact of tube potential and iodine concentration on the visibility of calcified plaques in coronary computed tomography angiography (cCTA).

Methods & Materials: 164 consecutive patients (65.9 % men and a mean age of 57.

Improved coronary artery contrast enhancement using noise-optimised virtual monoenergetic imaging from dual-source dual-energy computed tomography.

Purpose: To define optimal kiloelectron volt (keV) settings for virtual monoenergetic imaging (VMI) reconstruction at dual-energy coronary computed tomography angiography (DE-CCTA).

Method: Fifty-one DE-CCTA data sets (33 men; mean age, 63.9 ± 13.

Gadolinium-enhanced imaging of pediatric thoracic lymphoma: is intravenous contrast really necessary?

Objectives: Increasing awareness of potential side effects from gadolinium-based contrast agents has underlined the need for contrast-free magnetic resonance imaging (MRI). Numerous recent articles evaluated the risk of potential brain deposits, with the result that research is putting the focus more on alternative unenhanced imaging techniques. The aim of this study was to determine the need for contrast media for chest MRI in primary staging and follow-up care of lymphoma.

Comparison of thick- and thin-slice images in thoracoabdominal trauma CT: a retrospective analysis.

Purpose: To compare thick (5 mm) and thin slice images (1.5 mm) of lung, soft tissue, and bone window in thoracoabdominal trauma computed tomography.

Materials And Methods: 167 Patients that underwent thoracoabdominal trauma CT between November 2014 and December 2015 were included in the study.

Indication of whole body computed tomography in pediatric polytrauma patients-Diagnostic potential of the Glasgow Coma Scale, the mechanism of injury and clinical examination.

Objective: To evaluate the diagnostic potential of the Glasgow Coma Scale (GCS), the mechanism of injury (MOI) and clinical examination (CE) for the indication of whole body computed tomography (WBCT) in pediatric polytrauma patients.

Materials & Methods: 100 pediatric polytrauma patients with WBCT were analysed in terms of age, gender, (MOI), GCS, detected injury, FAST, CE and Injury Severity Score (ISS). Correlations between all clinical variables and patient groups with (p+) and without (p-) injury were assessed.

Using coronary CT angiography for guiding invasive coronary angiography: potential role to reduce intraprocedural radiation exposure.

Objectives: We investigated the potential reduction of patient exposure during invasive coronary angiography (ICA) if the procedure had only been directed to the vessel with at least one ≥ 50% stenosis as described in the CT report.

Methods: Dose reports of 61 patients referred to ICA because of at least one ≥ 50% stenosis on coronary CT angiography (CCTA) were included. Dose-area product (DAP) was documented separately for left (LCA) and right coronary arteries (RCA) by summing up the single DAP for each angiographic projection.

High-pitch dual-source paranasal sinus CT in agitated patients with maxillofacial trauma: analysis of image quality, motion artifacts, and dose aspects.

Background Image quality benefits from high-pitch scanning in agitated patients by reducing acquisition time. Purpose To compare image quality and exposure parameters in patients with maxillofacial trauma on second- and third-generation dual-source computed tomography (DSCT). Material and Methods Four groups were compared.
