Prognostic Value of Combined FDG PET and MRI Analysis of Cervical Cancer: A Systematic Review and Meta‐Analysis

Journal of Medical Radiation Sciences, EarlyView.
This systematic review and meta‐analysis synthesised FDG PET/MRWE biomarkers in cervical cancer, including a pooled analysis of the association between metabolic activity (SUV‐based metrics) and tumour diffusion characteristics (ADC measures). Prognostic evidence from the included studies was also analysed to identify PET‐ and MRI‐based parameters, as ...

High-Resolution IVIM MRI Characterizes Diffusion-Perfusion Properties of the Parasagittal Dura. [PDF]

NMR Biomed
Parasagittal dura demonstrates intermediate diffusion and elevated perfusion‐related IVIM metrics compared with brain parenchyma, reflecting its unique microfluidic environment at the CSF–dura interface. IVIM imaging of the parasagittal dura provides a rapid, noncontrast MRI approach to assess dural fluid transport and may offer a potential imaging ...

Deep Learning and Machine Learning Algorithms for Cervical Cancer Segmentation on MRI: A Systematic Review

Journal of Medical Radiation Sciences, EarlyView.
This systematic review summarizes current evidence on machine and deep learning algorithms for MRI‐based cervical cancer segmentation, demonstrating promising diagnostic performance and potential for workflow automation. However, methodological heterogeneity, limited external validation, and low certainty of evidence highlight the need for standardized

Artifacts on the DWI sequences.

, 2016
A) Example of artifacts on the high-resolution EPI-DWI (three consecutive slices shown). A typical susceptibility artifact is visible on the EPI-DWI (orange arrow)–note that such artifacts were ignored by the raters and are not the focus of this study ...
