Multiplexed sensitivity encoding diffusion-weighted imaging in the assessment of meningiomas: improving the image quality, grading accuracy, and proliferative activity evaluation.

ABSTRACT:

Background

Meningiomas often occur near the skull, where tumor imaging is prone to distortion and susceptibility artifacts, resulting in an unsatisfactory image quality of conventional single-shot echo-planar diffusion-weighted imaging (ssEPI-DWI). Our aim in this study was to evaluate the image quality of multiplexed sensitivity encoding diffusion-weighted imaging (MUSE-DWI) in meningiomas and the accuracy of the apparent diffusion coefficient (ADC) histogram parameters for tumor grading and proliferative activity evaluation based on MUSE-DWI and ssEPI-DWI.

Methods

A total of 73 consecutive patients with pathologically confirmed meningiomas were included in this prospective study. Three neuroradiologists independently assessed the image quality using a 5-point Likert scale,
