Computer-assisted surgery with three-dimensional (3D) printed surgical guides provides more accurate results than free-hand surgery. Steam sterilization could be one of the factors that affect dimensions guide resin materials, leading to inaccuracies during surgeries. The purpose this study was evaluate effects steam on dimensional accuracy indication-specific hollow cube test bodies, manufactured in-house using Class IIa biocompatible materials (proprietary and third-party). To pre-...
Reconstruction of cranial defects is an arduous task for craniomaxillofacial surgeons. Additive manufacturing (AM) or three-dimensional (3D) printing titanium patient-specific implants (PSIs) made its way into cranioplasty, improving the clinical outcomes in complex surgical procedures. There has been a significant interest within medical community redesigning based on natural analogies. This paper proposes workflow to create biomimetic prosthesis with interconnected strut macrostructure...
Abstract Three-dimensional (3D) printing of vascular structures is special interest for procedure simulations in Interventional Radiology, but remains due to the complexity system and lack biological tissue mimicking 3D materials a technical challenge. In this study, feasibility, accuracy, usability recently introduced silicone-like resin were evaluated endovascular technically compared commonly used standard clear resin. Fifty-four models based on twenty-seven consecutive embolization cases...
Abstract Violence seems deeply rooted in human nature and an endemic potential for such is today frequently associated with differing ethnic, religious or socio-economic backgrounds. Ethnic nepotism believed to be one of the main causes inter-group violence multi-ethnic societies. At site Els Trocs Spanish Pyrenees, rivalling groups either migrating early farmers indigenous hunter-gatherers collided violently around 5300 BCE. This clash apparently resulted a massacre farmers. The overkill...
Background Workloads in radiology departments have constantly increased over the past decades. The resulting radiologist fatigue is considered a rising problem that affects diagnostic accuracy. Purpose To investigate whether data mining of quantitative parameters from report proofreading process can reveal daytime and shift-dependent trends similarity as surrogate marker for resident fatigue. Materials Methods Data 117 402 reports written by residents between September 2017 March 2020 were...
OBJECTIVE. The purpose of this study is to validate an electronic learning, or e-learning, concept featuring gamification elements, rapid case reading, and instant feedback. SUBJECTS AND METHODS. An e-learning was devised that offered game levels for the providing training in detection pneumothorax 195 cases, with questions read succession feedback provided each case. user's task locate on chest radiographs indicate its presence by clicking a mouse. level design included entry test...
Manually performed diameter measurements on ECG-gated CT-angiography (CTA) represent the gold standard for diagnosis of thoracic aortic dilatation. However, they are time-consuming and show high inter-reader variability. Therefore, we aimed to evaluate accuracy a deep learning-(DL)-algorithm in comparison those radiologists evaluated measurement times (MT).We retrospectively analyzed 405 CTA exams 371 consecutive patients with suspected dilatation between May 2010 June 2019. The DL-algorithm...
MRI-targeted prostate biopsy improves detection of clinically significant cancer (PCa). However, up to 70% PCa lesions display intralesional tumor heterogeneity. Current target sampling strategies do not yet adequately account for this finding. This prospective study included 118 patients who underwent transperineal robotic assisted the prostate. We identified a total 58 PCa-positive PI-RADS lesions. compared diagnostic accuracy target-saturation strategy single, two, or three randomly...
Methods to assess three-dimensionally the breast surface are increasingly used in plastic and reconstructive surgery. The aim of this study was validate use Structure Sensor 3D scanner (Occipital, Inc., Boulder, CO, USA) connected an iPad Pro (Apple, Cupertino, CA, as a novel, inexpensive handheld three-dimensional scanning process.Surface images medical human female anatomy torso model rigid were repeatedly acquired with compared those obtained using two clinically established imaging...
To compare different methods of three-dimensional representations, namely 3D-Print, Virtual Reality (VR)-Glasses and 3D-Display regarding the understanding pathology, accuracy details, quality anatomical representation technical operability assessment possible change in treatment disciplines levels professional experience.
Thoracic aortic (TA) dilatation (TAD) is a risk factor for acute syndrome and must therefore be reported in every CT report. However, the complex anatomy of thoracic aorta impedes TAD detection. We investigated performance deep learning (DL) prototype as secondary reading tool built to measure TA diameters large-scale cohort.Consecutive contrast-enhanced (CE) non-CE chest exams with "normal" according their radiology reports were included. The DL-prototype (AIRad, Siemens Healthineers,...
Objectives To improve precision of secondary resection (SR) after positive surgical margin (PSM) detection by frozen section (FS) during nerve‐sparing (NS) robot‐assisted radical prostatectomy (RARP) employing a personalised three‐dimensional (3D)‐printed prostate model derived from pelvic magnetic resonance imaging (MRI). This was used to mark margins and guide intraoperative SR NS‐RARP. Patients Methods Prospective multicentre cohort study with 100 patients undergoing NS‐RARP between...
Abstract Imaging of the heart anatomy plays an important role, especially in catheter ablation for treatment arrhythmias adults with congenital disease (ACHD). We present a comprehensive overview current state‐of‐the‐art modalities available to plan and guide ACHD patient. In addition clinical assessment computed tomography integration 3D reconstructions into electroanatomical mapping system, printing virtual reality showed its value preprocedural planning intervention.
In a 32-year-old patient with chest pain, large, complex coronary-venous fistula additional feeders from the descending aorta was detected computed tomography. Multimodality imaging, including multicolor 3-dimensional printing, allowed precise anatomic visualization of origin, course and drainage site fistula. The treated conservatively. (Level Difficulty: Advanced.)
Objective: Investigating the influence of increasing intraabdominal pressure by Valsalva maneuvers and/or abdominal compression to reach best visualization entire urinary tract in computed tomography urography (CTU).Methods: After split-bolus technique, maneuvers, or a combination both were applied 60 patients before late phase images acquired. The degree opacification and distension three segments evaluated.Results: CT no significant difference among groups regarding distention...
Abstract Background/Introduction Substrate-based radiofrequency ablation (RFA) in combination with pre-procedural computed tomography (CT) or cardiac Magnetic Resonance Imaging (cMRI) emerged as a promising approach to treat ventricular tachycardias (VT). However, image-processing and 3D reconstruction of the relevant structures embed them into electroanatomical mapping (EAM) system is time consuming requires highly experienced personal dedicated software. Purpose The aim study was present...
A 73-year-old woman with exertional dyspnoea without retrosternal pain was referred for cardiac computed tomography angiography (CCTA). An anomaly of the coronary artery anatomy detected separate ostia left anterior descending (LAD) and circumflex (LCX) from sinus Valsalva (Figures 1 2, Supplementary material online, Figure S1, Videos 2). The LCX ostium located to LAD a proximal crossing identified epicardial superior LCX. Immediately distal crossing, septal branch separated Since CCTA scan...
