Breast Magnetic Resonance Image Analysis for Surgeons Using Virtual Reality: A Comparative Study

The treatment of breast cancer, the leading cause of cancer and cancer mortality among women worldwide, is mainly on the basis of surgery. In this study, we describe the use of a medical image visualization tool on the basis of virtual reality (VR), entitled DIVA, in the context of breast cancer tumor localization among surgeons. The aim of this study was to evaluate the speed and accuracy of surgeons using DIVA for medical image analysis of breast magnetic resonance image (MRI) scans relative to standard image slice-based visualization tools.

Partial breast resection for multifocal lower quadrant breast tumour using virtual reality

Oncoplastic surgery allows an increase in the number of indications for conservative breast cancer treatments. However, uncertainty as to whether it can be performed still exists in certain situations such as with multicentric or multifocal lesions, even when the breast volume can accommodate it. With the aid of a virtual reality software, DIVA, allowing the precise visualisation of tumours and breast volumes based entirely on the patient’s MRI, we report the ability to rapidly confirm and secure an indication for partial surgery of multiple lesions in a 31-year-old patient. With the described approach, the patient did not have to suffer significant disfigurement from cancerous breast surgery without compromising safety.

Fast-track VR for Cardiac Imaging in Congenital Heart Disease

We sought to evaluate the appropriateness of cardiac anatomy renderings by a new virtual reality (VR) technology, entitled DIVA, directly applicable to raw MRI imaging data without intermediate segmentation steps in comparison to standard 3D rendering techniques (3D PDF and 3D printing). Differences in post processing times were also evaluated.

DIVA, a 3D virtual reality platform, improves undergraduate craniofacial trauma education

Craniofacial fracture management is challenging to teach due to the complex anatomy of the skull, even when using three-dimensional (3D) CT-scan images. DIVA is a software allowing the straightforward visualization of CT-scans in a user-friendly 3D virtual reality (VR) environment. Here, we assess DIVA as an educational tool for craniofacial trauma for undergraduate medical students.

Management of ischiopagus twin separation with a focus on W–S incision design

Ischiopagus twins share parts of the spine, central nervous system, gastrointestinal and genitou-rinary tracts with various degrees of severity. Their separation is a surgical challenge. From the perspective of the plastic surgeon, one of the straightforward technical problems of conjoined twin separation is the coverage of the large residual parietal defects determined by the initial skin incisions.

This report provides a description of relevant incision design strategies for ischiopagus separation in order to minimize morbidity related to coverage issues, especially in the abdominal and perineal regions.
