Abstract Introduction Nephron-sparing surgery is becoming more common as surgical techniques advance. VR and 3D visualisation appear to provide better anatomical understanding in presurgical planning than two-dimensional alone. 3D models may enable greater tissue salvation and fewer complications. 3D model preparation and advancing research is expensive and time consuming. We aim to pilot study led by medical student, create reliable anatomical kidney models and assess usefulness in surgical planning. Method Routine CT urograms were performed on 128 slice scanner using split bolus technique. Medical student segmented and displayed models in VR using 3DSlicer. Radiology registrar and consultant validated models. Two urology surgeons completed qualitative questionnaires. Result We included two patients. Only minor segmentation tweaks by radiologist ensured accurately demonstrated tumors. Tissue contrast quality varied between CT scans complicating segmentation. Both surgeons deemed models helpful in visualising hilar anatomy, predicting bleeding complications, determining laparoscopic/open and partial/full nephrectomy approach. Surgeons prioritised vasculature visualisation over collecting system. Surgeons suggested gauging tumor depth would be useful. Considering 3D printing cost, surgeons agreed VR alone may suffice. Conclusion Surgeons found 3D and VR enabled accurate surgical planning and patient counselling regarding nephrectomy risk. Minor CT protocol recommendations enable easier and more accurate segmentation, without increasing patient's radiation exposure. Annual leave during 8-week summer project reflects case numbers. Since, we've identified more cases to assess surgical parameters against matched cohort. We've begun work for adrenal surgery. It's feasible for medical students with minimal surgical/radiological knowledge to advance this research, gaining valuable experience. Abbrev Virtual Reality(VR), Three-dimensional(3D), Computerised Tomography(CT) Take-home message Three-dimensional imaging and virtual reality may improve surgical planning and patient counselling. Regarding nephrectomy, this could give surgeons the confidence to convert from full nephrectomy to partial nephrectomy approach, improving patient outcome.

Three Dimensional Models

Abstract Background: Medical trainees frequently note that cardiac anatomy is difficult to conceive within a two dimensional framework. The dynamics of flow and nuances of defects become more apparent when framed in three-dimensional models. Given the evidence of improved comprehension using such modeling, this study aimed to contribute further to that understanding by comparing Virtual Reality (VR) and 3D printed models (3DP) in medical education. Objectives: We sought to systematically compare the perceived subjective effectiveness of Virtual Reality (VR) and 3D printed models (3DP) in the educational experience of residents and nurse practitioners. Methods: Trainees and practitioners underwent individual 15-minute teaching sessions in which features of an anatomically normal heart as well as a congenitally diseased heart were demonstrated using both Virtual Reality (VR) and 3-D printed models (3DP). Participants then briefly explored each modality before filling out a short survey in which they identified which model (3DP or VR) they felt was more effective in enhancing their understanding of cardiac anatomy and associated defects. The survey included a binary summative assessment and a series of Likert scale questions addressing usefulness of each model type and degree of comfort with each modality. Results: 27 pediatric residents and 3 nurse practitioners explored models of normal heart and tetralogy of Fallot pathology. Participants endorsed a greater degree of understanding with VR models (8.5±1) compared with 3D Printed models (6.3±1.8) or traditional models of instruction (5.5±1.5) p<0.001. Most participants had minimal prior exposure to VR (1.1 ± 0.4) or 3-D printed models (2.1 ± 1.5). Most participants felt comfortable with modern technology (7.6 ± 2.1). 87% of participants preferred VR over 3DP. Conclusions: Our study shows that, overall, VR was preferred over 3DP models by pediatric residents and nurse practitioners for understanding cardiac anatomy and pathophysiology.

Three-dimensional speckle-tracking echocardiography is a new cardiac imaging methodology, which allows three-dimensional non-invasive evaluation of the myocardial mechanics. The aim of this review is to present this new tool emphasizing its diagnostic potentials and demonstrating its limitations, as well. Orv. Hetil., 2012, 153, 1570–1577.
