Medical three-dimensional (3D) printing has expanded dramatically over the past three decades with growth in both facility adoption and variety of medical applications. Consideration for each step required to create accurate 3D printed models from imaging data impacts patient care management. In this paper, a writing group representing Radiological Society North America Special Interest Group on Printing (SIG) provides recommendations that have been vetted voted by SIG active membership....
To define and evaluate coronary contrast opacification gradients using prospectively ECG-gated single heart beat 320-detector row angiography (CTA).Thirty-six patients with normal arteries determined by 320 x 0.5-mm detector CTA were retrospectively evaluated customized image postprocessing software to measure Hounsfield Units at 1-mm intervals orthogonal the artery center line. Linear regression correlation between mean distance from ostium (regression slope defined as gradient G(d)), lumen...
Hand-held three dimensional models of the human anatomy and pathology, tailored-made protheses, custom-designed implants can be derived from imaging modalities, most commonly Computed Tomography (CT). However, standard DICOM format images cannot 3D printed; instead, additional image post-processing is required to transform interest into Standard Tessellation Language (STL) needed. This conversion, subsequent printing STL file, requires a series steps. Initial involves...
Medical 3D printing is expanding exponentially, with tremendous potential yet to be realized in nearly all facets of medicine. Unfortunately, multiple informal subdomain-specific isolated terminological 'silos' where disparate terminology used for similar concepts are also arising as rapidly. It imperative formalize the foundational at this early stage facilitate future knowledge integration, collaborative research, and appropriate reimbursement. The purpose work develop objective,...
The association of low endothelial shear stress (ESS) with high-risk plaque (HRP) has not been thoroughly investigated in humans. We the local ESS and lumen remodelling patterns HRPs using optical coherence tomography (OCT), developed score, explored its prevalence clinical outcomes.A total 35 coronary arteries from 30 patients stable angina or acute syndrome (ACS) were reconstructed three dimensional (3D) OCT. was calculated computational fluid dynamics classified into low, moderate, high...
Background Detecting and segmenting intracranial aneurysms (IAs) from angiographic images is a laborious task. Objective To evaluates novel deep-learning algorithm, named vessel attention (VA)-Unet, for the efficient detection segmentation of IAs. Methods This retrospective study was conducted using head CT angiography (CTA) examinations depicting IAs two hospitals in China between 2010 2021. Training included cases with subarachnoid hemorrhage (SAH) arterial stenosis, common accompanying...
Background: Facial allotransplantation requires a detailed arterial and venous assessment for surgical planning. Target vessels are often depleted by multiple reconstructive attempts or the severe facial injury itself. The purpose of this study was to retrospectively compare diagnostic performance computed tomography magnetic resonance angiography in preoperative assessment. Methods: Four-dimensional (three spatial planes plus time) tomographic images including 126 potential (76 arteries 50...
3D-printed models are increasingly used for surgical planning. We assessed the utility, accuracy, and reproducibility of 3D printing to assist visualization complex thoracic tumors planning.Models were created from pre-operative images three patients using a standard radiology workstation. Operating surgeons model utility Gillespie scale (1 = inferior 4 superior), accuracy compared intraoperative findings. Model variability was one patient whom two independently. The subjectively by...
Medical 3D printing holds the potential of transforming personalized medicine by enabling fabrication patient-specific implants, reimagining prostheses, developing surgical guides to expedite and transform interventions, a growing multitude specialized applications. In order realize this tremendous in frontline medicine, an understanding basic principles medical professionals is required. This primer underlines approaches tools printing, starting from patient anatomy acquired through...
