Impact of Discordance Between Magnetic Resonance Imaging and Ultrasound Volume Measurements on Prostate Fusion Biopsy Outcomes.
J Urol
December 2024
Center for Interventional Oncology, Radiology and Imaging Sciences, Clinical Center, National Institutes of Health, Bethesda, Maryland.
Purpose: To determine whether the difference between MRI-based and ultrasound (US)-based volume measurements are associated with MRI/US-targeted fusion-guided biopsy outcomes.
Materials And Methods: This retrospective, single-center study involved 4177 consecutive patients biopsied between 2010 and 2023 using both MRI/US-targeted fusion and systematic biopsy. Biopsies were indicated because of elevated PSA levels or abnormal multiparametric MRI results.
Multivariate Brain Tumor Detection in 3D-MRI Images Using Optimised Segmentation and Unified Classification Model.
J Eval Clin Pract
February 2025
Department of Electronics and Communication Engineering, Sri Muthukumaran Institute of Technology, Chennai, Tamil Nadu, India.
Article Synopsis
- 3D-MRI analysis of brain tumors is crucial for diagnosis and treatment, but existing segmentation techniques struggle with errors due to poor initial contour extraction and overlapping tissue intensity.
- A new Duo-step optimised Pyramidal SegNet addresses these issues by enhancing contrast and minimizing segmentation errors while effectively extracting tumor regions from 2D MRI slices.
- The proposed method shows significant improvements in detection rates for multivariate brain tumors, achieving precision rates above 97%, recall scores of 99%, and overall accuracy exceeding 95% on the BraTS2020 and Brain Tumor Detection 2020 data sets.
Pilot analysis of magnetic resonance imaging-based contributors to patient-centred optimization of mandibular advancement devices in obstructive sleep apnea.
J Sleep Res
November 2024
Fraunhofer Research Institution for Individualized and Cell-Based Medical Engineering IMTE, Lübeck, Germany.
Mandibular advancement devices are an effective treatment option for obstructive sleep apnea. While their efficacy depends on the degree of mandibular protrusion, other contributing factors influencing the optimal outcome are not fully understood. This magnetic resonance imaging-based pilot study aimed at investigating whether there are promising planimetric parameters that may be related to the optimal therapeutic position.

Clinical Professor, Division of Applied Oral Sciences and Community Dental Care, Faculty of Dentistry, The University of Hong Kong, Hong Kong, PR China.. Electronic address:
Statement Of Problem: Removable dental prosthesis cleanliness is multifactorial, and key clinical and nonclinical factors associated with prosthesis hygiene should be identified to inform practice, particularly given the dearth of studies relating specifically to prosthetic factors and prosthesis cleanliness.
Purpose: The purpose of this cross-sectional clinical study was to evaluate removable dental prosthesis cleanliness among community-dwelling elders by using a semi-automated planimetric assessment and to determine factors associated with removable prosthesis cleanliness.
Material And Methods: The cross-sectional study was conducted among community-dwelling elders wearing removable prostheses.
High correlation of quantitative susceptibility mapping and echo intensity measurements of nigral iron overload in Parkinson's disease.
J Neural Transm (Vienna)
November 2024
Department of Neurology, Rostock University Medical Center, Gehlsheimer Str. 20, 18147, Rostock, Germany.
Article Synopsis
- This study examined the connection between two imaging techniques, Quantitative Susceptibility Mapping (QSM) and Transcranial Sonography (TCS), to evaluate iron levels in the substantia nigra of patients with Parkinson's disease (PD).
- Eighteen imaging sessions were conducted on 15 PD patients, revealing strong correlations between nigral iron susceptibility and TCS measurements of echogenicity.
- The findings suggest that increased iron accumulation in the substantia nigra may contribute to the observed echogenicity in PD, with echogenicity likely reflecting stored ferritin-bound iron in microglia.
