The purpose of this study was to evaluate the capabilities photon-counting (PC) CT combined with artificial intelligence-derived coronary computed tomography angiography (PC-CCTA) stenosis quantification and fractional flow reserve prediction (FFRai) for assessment artery disease (CAD) in transcatheter aortic valve replacement (TAVR) work-up.
The aim of this paper is to evaluate the diagnostic image quality spectral dual-source photon-counting detector coronary computed tomography angiography (PCD-CCTA) for artery disease in a multicenter study. (IQ), assessability, contrast-to-noise ratio (CNR), Agatston score, and radiation exposure were measured. Stenoses quantified compared with invasive angiography, if available. A total 92 subjects (65% male, age 58 ± 14 years) analyzed. prevalence significant (CAD) (stenosis ≥ 50%) was 17%...
Our aim was to compare the image quality and patient dose of contrast-enhanced oncologic chest-CT a first-generation photon-counting detector (PCD-CT) second-generation dual-source dual-energy CT (DSCT). For this reason, one hundred consecutive patients (63 male, 65 ± 11 years, BMI: 16–42 kg/m2) were prospectively enrolled evaluated. Clinically indicated obtained with PCD-CT compared previously chest-DSCT in same individuals. The median time interval between scans three months. contrast...
Subjective and objective image quality comparison of bone microstructure disease-related abnormalities in multiple myeloma patients using a 1st-generation dual-source photon-counting detector CT(DS-PCD-CT) 2nd-generation dual-energy (energy-integrating detector) CT (DS-EID-CT).Fifty (mean age 67.7 ± 10.9 years,16 females) were prospectively enrolled. Unenhanced whole-body CTs clinically indicated performed on DS-EID-CT DS-PCD-CT (median time difference: 12 months). was Quantumplus UHR mode...
Detecting ongoing inflammation in myocarditis patients has prognostic relevance, but there are limited data on the detection of chronic and its differentiation from healed myocarditis.
The optimal treatment of unruptured middle cerebral aneurysms is still under debate. Although today almost any aneurysm can be treated endovascularly, there a lack data comparing endovascular and microsurgical repair MCA aneurysms. aim our analysis to provide on the efficacy, clinical outcome, complications re-treatment rates this subtype aneurysms.Between May 2008 July 2017, 1184 in 827 patients was performed department. Twenty-four percent these were located at MCA, 150 bifurcation with...
To provide clinically relevant criteria for differentiation between the athlete's heart and similar appearing hypertrophic (HCM), dilated (DCM), arrhythmogenic right-ventricular cardiomyopathy (ARVC) in MRI. 40 top-level athletes were prospectively examined with cardiac MR (CMR) two university centres compared to retrospectively recruited patients diagnosed HCM (n = 14), ARVC 18), DCM 48). Analysed imaging parameters whole study cohort included morphology, functional late gadolinium...
To compare the diagnostic characteristics between arterial phase imaging versus portal venous imaging, applying polychromatic T3D images and low keV virtual monochromatic using a 1st generation photon-counting CT detector, of in patients with hepatocellular carcinoma (HCC).Consecutive HCC, clinical indication for were prospectively enrolled. Virtual monoenergetic (VMI) reconstructed at 40 to 70 PCD-CT. Two independent, blinded radiologists counted all hepatic lesions quantified their size....
To evaluate computed tomography fractional flow reserve (FFRCT) values in distal parts of the coronaries an asymptomatic cohort marathon runners without any coronary stenosis for potentially false-positive values.Ninety-eight male (age 53 ± 7 years) were enrolled a prospective monocentric study and underwent angiography (CCTA). CCTA data analyzed visual artery stenosis. FFRCT was evaluated 59 participants proximal, mid, sections using on-site software prototype.In stenosis, abnormal ≤ 0.8...
Abstract Purpose This study evaluates the diagnostic performance of artificial intelligence (AI)-based coronary computed tomography angiography (CCTA) for detecting artery disease (CAD) and assessing fractional flow reserve (FFR) in asymptomatic male marathon runners. Material methods We prospectively recruited 100 runners over age 45 CAD screening. CCTA was analyzed using AI models (CorEx Spimed-AI) on a local server. The focused significant (≥ 50% diameter stenosis, CAD-RADS 3, 4, or 5)...
The aim of this study is to evaluate the correlation between background parenchymal enhancement (BPE) and various patient-related technical factors in recombined contrast-enhanced spectral mammography (CESM) images.
The purpose of this study was to evaluate whether changes in repeated lung ultrasound (LUS) or chest X-ray (CXR) coronavirus disease 2019 (COVID-19) patients can predict the development severe and need for treatment intensive care unit (ICU). In prospective monocentric study, COVID-19 received standardized LUS CXR at day 1, 3 5. Scores (LUS score) (RALE M-RALE) were calculated compared. Intra-class correlation two readers ROC analysis best discriminator ICU treatment. A total 30 analyzed, 26...
(1) Background and Objectives: Dark-blood late gadolinium enhancement has been shown to be a reliable cardiac magnetic resonance (CMR) method for assessing viability depicting myocardial scarring in ischemic cardiomyopathy. The aim of this study was evaluate dark-blood LGE imaging compared with conventional bright-blood the detection non-ischemic cardiomyopathies. (2) Materials Methods: Patients suspected cardiomyopathy were prospectively enrolled single-centre from January 2020 March 2023....
