Association of Regional White Matter Hyperintensity Volumes with Cognitive Dysfunction and Vascular Risk Factors In Patients With Amnestic Mild Cognitive Impairment

Publication: Geriatr Gerontol Int. 2021 Jun 9. PMID: 34105230 Authors: Hirao K, Yamashita F, Sakurai S, Tsugawa A, Haime R, Fukasawa R, Sato T, Kanetaka H, Umahara T, Sakurai H, Hanyu H, Shimizu S. Institution: Department of Geriatric Medicine, Tokyo Medical University, Tokyo, Japan. Abstract: White matter hyperintensities (WMH) obtained by magnetic resonance imaging (MRI) have been reported to promote neurodegeneration and cognitive decline in patients with mild cognitive impairment (MCI). However, little is known about the association between regional WMH (rWMH) and cognitive dysfunction in MCI. We hence investigated the associations between rWMH volumes and cognitive dysfunction in MCI. PVH and DWMH lesions were outlined by a neurologist, using the semiautomated freeware 3D Slicer, which is a freely available, open-source software package for the visualization, registration, segmentation, and quantification of medical data.

A New Method to Determine the Optimal Orientation of Slim Modiolar Cochlear Implant Electrode Array Insertion

Publication: Ideggyogy Sz. 2021 May 30;74(5-6):191-195. PMID: 34106549 Authors: Horváth B, Perényi Á, Molnár AF, Csanády M, Kiss GJ, Rovó L. Institution: University of Szeged, Doctoral School of Clinical Medicine, Szeged, Hungary. Abstract: Our goal was to determine the optimal orientation of insertion of the Slim Modiolar electrode and develop an easy-to-use method to aid implantation surgery. In some instances, the electrode arrays cannot be inserted in their full length. This can lead to buckling, interscalar dislocation or tip fold-over. In our opinion, one of the possible reasons of tip fold-over is unfavourable orientation of the electrode array. Our goal was to determine the optimal orientation of the Slim Modiolar electrode array relative to clear surgical landmarks and present our method in one specified case. For the measurement, we used the preoperative CT scan of one of our cochlear implant patients. These images were processed by an open source and free image visualization software: 3D Slicer.

Impact of the Craniofacial Surgery Simulation in Anterior Plagiocephaly on Orbits and Oculomotor Muscles: Biomechanical Analysis With a Finite Element Model

Publication: J Craniofac Surg. 2021 May 28. PMID: 34054084 Authors: Dalmas F, Thollon L, Beylerian M, Godio Raboutet Y, David T, Scavarda D, Denis D, Pech-Gourg G. Institution: Department of Ophthalmology, University Medical Center, Marseille, France. Abstract: The aim of this study was to show the displacements and strain induced by the supraorbital band advancement during a craniofacial surgery for an anterior plagiocephaly on the orbital bones and the orbital content thanks to a numerical surgical simulation using the finite element method. A three-dimensional (3D) finite element model of a child with an anterior plagiocephaly was entirely created from a tomodensitometry of a patient followed by our Craniofacial Pediatric team. Data of the tomodensitometry were computed with 3D Slicer to re-create the orbit geometry.

Comparing Three-Dimensional Models of Placenta Accreta Spectrum With Surgical Findings

Publication: Int J Gynaecol Obstet. 2021 May 17. PMID: 33998689 Authors: Mulligan KM, Bartels HC, Armstrong F, Immel E, Corcoran S, Walsh JM, McAuliffe F, McParland P, Carroll S, Higgins S, Mahony R, Donnelly J, Geoghegan T, Colleran G, O'Cearbhaill E, Downey P, Brennan DJ. Institution: UCD School of Medicine, National Maternity Hospital, Dublin, Ireland. Abstract: Placenta accreta spectrum (PAS) is associated with significant maternal morbidity mainly related to blood loss. Pre-operative planning is aided by antenatal ultrasound and magnetic resonance imaging. We sought to assess whether three-dimensional (3D) models from MR images were accurate when compared with surgical and pathological findings. Digital Imaging and Communications in Medicine files containing MR images with varying severity of PAS (n = 4) were modeled using 3D Slicer.

Optimization of Manufacturing Parameters and Tensile Specimen Geometry for Fused Deposition Modeling (FDM) 3D-Printed PETG

Publication: Materials (Basel). 2021 May 14;14(10):2556. PMID: 34069230 | PDF Authors: Özen A, Auhl D, Völlmecke C, Kiendl J, Abali BE. Institution: Institute of Material Science and Technology, Technische Universität Berlin, Germany. Abstract: Additive manufacturing provides high design flexibility, but its use is restricted by limited mechanical properties compared to conventional production methods. As technology is still emerging, several approaches exist in the literature for quantifying and improving mechanical properties. In this study, we investigate characterizing materials' response of additive manufactured structures, specifically by fused deposition modeling (FDM). A comparative analysis is achieved for four different tensile test specimens for polymers based on ASTM D3039 and ISO 527-2 standards. Comparison of specimen geometries is studied with the aid of computations based on the Finite Element Method (FEM). Uniaxial tensile tests are carried out, after a careful examination of different slicing approaches for 3D printing. We emphasize the effects of the chosen slicer parameters on the position of failures in the specimens and propose a simple formalism for measuring effective mechanical properties of 3D-printed structures. "...this CAD model is converted by software, called a 3D Slicer, to a 3D printing code, where process information is supplied for manufacturing."

The Use of Cochlear-Enhancement Imaging to Predict Hearing Preservation Following Vestibular Schwannoma Removal

Publication: J Neurosurg Sci. 2021 May 3. PMID: 33940784 Authors: Kim WH, Park HH, Ahn SJ, Park M, Hong CK. Institution: Department of Neurosurgery, Brain Tumor Center, Gangnam Severance Hospital, Yonsei University Health System, Seoul, Republic of Korea. Abstract: Background: Hearing preservation is challenging for patients after the removal of large vestibular schwannomas (VSs). Here, using preoperative magnetic resonance (MR) imaging, we investigated the significance of cochlear enhancement (CE) for predicting postoperative hearing preservation. Methods: Between January 2014 and December 2019, 34 VS-patients with serviceable hearing underwent tumor-removal surgery using a retrosigmoid approach. The presence or absence of CE using both T2-weighted and gadolinium-enhanced T1-weighted MR images was assessed in VS patients using the pixel-analysis method. Segmented volumetric analyses were also performed using GrowCut 3D Slicer software.
