Abstract Objective To evaluate the success and complications of thermal ablation (TA) based on voluntary, prospective registry German Society for Interventional Radiology Minimally Invasive Therapy (DeGIR) with 303 participating centers from Germany, Austria, Switzerland. Materials methods Registry data 2018 until 2023 1102 patients small renal tumors (age: 72.5 ± 11.6 years; female: 33.6%, 370/1102) were analyzed. Hospitals ≥ 20 TAs considered high-volume centers. Technical complication...
Abstract Objective Determination of coronary artery calcium scoring (CACS) in non-contrast computed tomography (CT) images has been shown to be an important prognostic factor disease (CAD). The objective this study was evaluate the accuracy CACS from virtual (VNC) imaging generated spectral data comparison standard (true) (TNC) a representative patient cohort with clinically approved software. Methods One hundred three patients referred CTA suspicion CAD were investigated on dual-layer...
Abstract Background A deep learning (DL) model that automatically detects cardiac pathologies on MRI may help streamline the diagnostic workflow. To develop a DL to detect T1-mapping and late gadolinium phase sensitive inversion recovery (PSIR) sequences were used. Methods Subjects in this study either diagnosed with pathology ( n = 137) including acute chronic myocardial infarction, myocarditis, dilated cardiomyopathy, hypertrophic cardiomyopathy or classified as normal 63). Cardiac MR...
Visceral artery aneurysms (VAA) are rare, and data on their occurrence treatment often outdated or heterogeneous. The objective of this study is to provide a comprehensive overview features interventional options for VAA.We analyzed demographic, procedural, clinical VAA from 2018 2022 based derived the German Society Interventional Radiology Minimally Invasive Therapy (DeGIR) registry regarding demographic details, aneurysm characteristics, processes, outcomes such as technical success,...
Purpose Modern non-invasive evaluation of Coronary Artery Disease (CAD) requires non-contrast low dose Computed Tomography (CT) imaging for determination Calcium Scoring (CACS) and contrast-enhanced vascular stenosis. Several methods calculation CACS from images have been proposed before. The main principle that is generation virtual by iodine subtraction a spectral CT dataset. However, those techniques some limitations: Dual-Source can lead to increased radiation exposure, switching the...
Blood flow through the cavities of heart and great vessels is pulsatile subject to time multidirectional variations. To date, recording blood in multiple directions phases has been limited. 4D-flow MRI offers advantages for recording, visualization analysis flow. The status quo method was summarized with PubMed database using keywords "4D-flow MRI, phase-contrast magnetic resonance imaging, MR imaging/visualization, quantification, 3 D cine (time-resolved) CMR, three-directional...
Trans-arterial radioembolization (TARE) is increasingly evaluated for unresectable intrahepatic cholangiocarcinoma (ICC). Not all ICC patients benefit equally well from TARE. Therefore, we sought to evaluate variables predicting progression-free survival (PFS) and overall (OS). Patients with non-resectable underwent TARE were treated 90Y resin microspheres. Baseline characteristics, biochemical/clinical toxicities, response examined impact on PFS OS. A total of 103 treatments administered 73...
Background Since the outbreak of COVID-19 pandemic, a number risk factors for poor outcome have been identified. Thereby, cardiovascular comorbidity has major impact on mortality. We investigated whether coronary calcification as marker artery disease (CAD) is appropriate prediction in COVID-19. Methods Hospitalized patients with (n = 109) were analyzed regarding clinical after native computed tomography (CT) imaging screening. CAC (coronary calcium score) and (need intensive care treatment...
Especially patients with aortic aneurysms and multiple computed tomography angiographies (CTA) might show medical conditions which oppose the use of iodine-based contrast agents. CTA using monoenergetic reconstructions from dual layer CT gadolinium (Gd-)based agents be a feasible alternative in these patients. Therefore, purpose this study was to evaluate feasibility clinical spectral Gd-based agent aneurysms.
In hepatitis C virus (HCV) infection, morbidity and mortality often result from extrahepatic disease manifestations. We provide evidence for a role of receptors the innate immune system in virally induced inflammation endothelium vitro vivo. Corresponding to finding an HCV-dependent induction proinflammatory mediators endothelial cells, mice treated with poly (I:C) exhibit significant reduction leukocyte rolling velocity, increase adhesion vessel wall increased extravasation leukocytes. HCV...
Aim Diagnostic evaluation practices for suspected coronary artery disease (CAD) may vary between countries. Our objective was to compare a CT-derived fractional flow reserve (FFR CT ) diagnostic strategy with usual care in patients planned invasive angiography (ICA) enrolled the PLATFORM (Prospective Longitudinal Trial of FFR : Outcome and Resource Impacts) study at German sites. Methods Patients were divided into two consecutive observational cohorts, receiving either or (CTA)/FFR . The...
Computed tomography angiography (CTA) requires IV application of iodine-based contrast agents. There are several medical conditions in which is not advisable or even feasible, especially for elective examinations. Novel techniques such as monoenergetic reconstructions from dual-energy computed tomographic (CT) data have been shown to increase radiation attenuation gadolinium (Gd)-based agents a phantom model. Therefore, the purpose present investigation was evaluate technical feasibility and...
Lymph nodes (LN) are examined in every computed tomography (CT) scan. Until now, an evaluation is only possible based on morphological criteria. With dual-energy CT (DECT) systems, iodine concentration (IC) can be measured which could conduct improved diagnostic of LNs.To define standard values for IC cervical, axillary, and inguinal LNs DECT.Imaging data 297 patients who received a DECT scan the neck, thorax, abdomen-pelvis, or combination those portal-venous phase were retrospectively...
Endovascular interventional radiological procedures have become the mainstay for treatment of critical limb ischemia (CLI) due to arterial stenosis or occlusion. Open surgical endovascular procedures, such as percutaneous transluminal angioplasty (PTA) stenting can be used a strategy. The aim is evaluate success and major complication rates radiology treatments CLI in Germany 2021, compare these results with internationally published data.
Endovascular treatment has emerged as the gold standard for managing chronic mesenteric ischemia (CMI) resulting from arterial stenosis or occlusion. This study aimed to assess efficacy and complication rates of continuous interventional radiology CMI in Germany between 2018 2021, comparing these findings with international quality standards.
Interventional procedures have become a mainstay in the therapy of acute limb ischemia caused by embolism or arterial thrombosis. Treatment options include pharmacological thrombolysis (PT) and mechanical thrombectomy (MT). The aim this study was to evaluate success major complication rates interventional radiological treatments thrombosis Germany 2021 compare their results with accepted international quality standards. Data for PT MT obtained from management system German society (DeGIR)....
