Video-Based Teaching of Image-Guided Breast Interventions: Stereotactic Core Biopsy Using a Prone Table.

ABSTRACT: Introduction:The introduction of new technologies and teaching strategies to educate the digital learner creates the potential for a better and more standardized training experience across programs. Thus, we sought to create an instructional video on stereotactic core breast biopsy that simulates best practices and could be readily accessed by training programs to improve and standardize resident education. Methods:At our institution, we use the video and questions as part of a flipped classroom educational activity. Residents are requested to complete the questions at home and watch the video. They then take the posttest questions during the lecture period, at which time the answers are reviewed and there is additional discussion of the procedure. The tests contain both video-related questions and control questions. Results:After viewing the video, there was a 30% mean improvement in the video-related questions compared to a 0% improvement in the control set of questions. Discussion:An instructional video on stereotactic core biopsy was created with associated assessment questions that can be used at any institution for the purposes of improving and standardizing training in breast imaging procedures. This resource can be especially useful for programs where trainees have limited procedure exposure.

Project description:Objective. Stereotactic technology enables fine navigation to small structures in the human body. While current stereotactic systems facilitate accurate targeting, they are mechanically cumbersome and limited in scope. Here, we hypothesized that a stereotactic system could be developed with a reduced footprint while maintaining broad targeting capabilities in order to improve versatility in frame placement location and surgical workflow.Approach. We designed a stereotactic system around the center-of-arc principle, with mechanical properties that would enable a compact design and ample targeting and trajectory maneuverability. To examine the opportunity for a low-cost rapidly-deployable system we developed two fabrication variants, one using three dimensional (3D)-printing and the other using conventional machining. Mechanical and image-guided accuracies were tested in phantom studies using magnetic resonance imaging (MRI) and computed tomography. Using human cadaver head specimens, we assessed the system's surgical workflow and its ability to reliably and accurately implant electrodes in deep brain stimulation (DBS) surgery.Main results. We developed a small 7.7 × 5.4 cm2device platform that rigidly mounts to curvilinear bone and supports the attachment of surgical instrumentation. Attachment of two surgical instruments, an imaging localizer and a compact targeting device, demonstrated successful MRI-guided intervention in phantom studies with a vector error of 1.79 ± 0.41 mm. Evaluation of the 3D-printed system for DBS surgery confirmed ease of device platform attachment and instrument functionality, as well as demonstrated a surgical targeting accuracy of 1.83 ± 0.15 mm. In addition, we found the surgical time to be 78.3 ± 5.4 min for bilateral electrode implantation.Significance. We developed a light and compact stereotactic system whose accuracy is on par with those used clinically. This technology is suitable for clinical translation and its flexibility in positioning will seamlessly expand the capabilities for stereotaxy to treat a wide range of conditions, both within neurosurgery and beyond.
