Post-mortem computed tomography (PMCT) has become a standard procedure in many forensic institutes worldwide. However, the scan protocols offered by vendors are optimised for clinical radiology and its main considerations regarding (CT), namely, radiation exposure motion artefacts. Thus, these aim at low-dose imaging fast techniques. negligible post-mortem imaging, which allows significantly increased image quality. Therefore, parameters have to be adjusted achieve best Several affect...
Refraction-based x-ray imaging can overcome the fundamental contrast limit of computed tomography (CT), particularly in soft tissue, but so far has been constrained to high-dose ex vivo applications or required highly coherent sources, such as synchrotrons. Here we demonstrate that grating interferometry (GI) is more dose efficient than conventional CT human breast under close-to-clinical conditions. Our system, based on a source and commercial gratings, outperformed for spatial resolutions...
Purpose To evaluate whether gadolinium penetrates human cerebrospinal fluid (CSF) after MR imaging (MRI) with a gadolinium-based contrast agent (GBCA). Materials and Methods For this retrospective study, the authors analyzed 60 CSF samples from 57 patients (median age, 50 years; range, 3-92 years) who underwent one material-enhanced MRI examination gadoterate meglumine within days of extraction between January December 2016. without material administration (n = 22) or those contrast-enhanced...
Objective The aim of the study is to compare image quality and homogeneity vessel enhancement in high-pitch CT-angiography aorta (CTA) prior transcatheter aortic valve implantation between bolus tracking with a fixed trigger delay patient-specific delay. Materials Methods In this retrospective study, consecutive patients who received CTA January 2023 June 2024 were included. Patients imaged using either (Group A; 15 seconds) or B; FAST Bolus; Siemens Healthineers AG). same contrast injection...
The principal concern of any radiation exposure in computed tomography (CT) is the induction stochastic risks developing a radiation-induced cancer. results given this manuscript will allow to (re-)calculate yield chest CT.To demonstrate method evaluate lifetime attributable risk (LAR) cancer incidence/mortality due single diagnostic investigation 1-year cohort consecutive CT for suspected pulmonary embolism (PE).A PE using standard scan protocol was analyzed retrospectively (691 patients,...
The discussion about setting up a program for lung cancer screening was launched with the publication of results National Lung Screening Trial, which suggested reduced mortality in high-risk subjects undergoing CT screening. However, important questions benefit-harm balance and details its cost-effectiveness remain unanswered. A panel specialists chest radiology, respiratory medicine, epidemiology, thoracic surgery representing all Swiss university hospitals prepared this joint statement...
The aim of this study was to compare a compressed-sensing free-breathing VIBE (fbVIBE) with conventional breath-hold (bhVIBE) for dynamic contrast-enhanced imaging the upper abdomen.In total, 70 datasets (bhVIBE, n = 30; fbVIBE 40; hard-gated [hg] reconstruction, motion-state-resolved [mr] 10) were assessed by 2 experienced readers. Both sequences performed on 1.5-T magnetic resonance scanners. prototypical sequence acquired navigation signal along data and supported different...
OBJECTIVE: To extract pulmonary and cardiovascular metrics from chest CTs of patients with coronavirus disease 2019 (COVID-19) using a fully automated deep learning-based approach assess their potential to predict patient management. MATERIALS AND METHODS: All initial who tested positive for severe acute respiratory syndrome 2 at our emergency department between March 25 April 25, 2020, were identified (n = 120). Three management groups defined: group 1 (outpatient), (general ward), 3...
Background: Central venous catheters (CVCs) are indispensable tools in intensive care and emergency medicine. CVC malpositions still occur frequently can cause various complications leading to increased patient mortality. A microbubbles test (MBT) be used confirm correct positioning. However, there is serious doubt regarding whether the currently applied threshold of a 2 s push-to-bubbles time (PTB time) for rapid atrial swirl sign (RASS) an MBT reliable accurate. The aim present study was...

Follow-up is essential for the early detection of recurrent non-muscle invasive bladder cancers (NMIBC). This study investigates clinical relevance new diagnostic tools such as an mRNA-based urine test (XPERT© Bladder Cancer Monitor, XBCM) and Narrow Band Imaging© (NBI) compares them with established follow-up diagnostics (white-light cystoscopy (WLC) cytology). was a prospective, double-blind, single-center that involved patients undergoing NMIBC screening at tertiary care center....
Schistosomiasis is a helminthic infection that endemic in tropical and subtropical regions. Pulmonary involvement can be divided into two categories: acute or chronic compromise. Chronic recurrent develops persons living travelling areas. In the lungs, granuloma formation fibrosis around schistosome eggs retained pulmonary vasculature may result obliterative arteriolitis hypertension leading to cor pulmonale. Acute schistosomiasis associated with primary exposure commonly seen nonimmune...
Presence of right ventricular thrombus (RVT) is a rare but life-threatening condition, thus immediate diagnosis and therapy are mandatory. Unfortunately, detection distinction from intraventricular tumour masses or vegetations represent complex task. Furthermore, consecutive principally led by clinical presentation without considering morphological features the thrombus. Current literature suggests multimodal non-invasive imaging approach. In this article, we discuss role cardiac magnetic...
Abstract Objectives Different computed tomography (CT) scanners, variations in acquisition protocols, and technical parameters employed for image reconstruction may introduce bias the analysis of pericoronary adipose tissue (PCAT) attenuation derived from coronary angiography (CCTA). Therefore, aim this study was to establish effect tube voltage, measured as kilovoltage peak (kVp), iterative on PCAT mean (PCAT MA ). Methods Twelve healthy ex vivo porcine hearts were injected with...
