Area of Science:

  • Neuroradiology
  • Oncology
  • Medical Imaging

Background:

  • Preoperative prediction of meningioma consistency is crucial for patient management.
  • Objective quantitative criteria for predicting meningioma consistency are lacking.
  • This study explores MRI histogram parameters for predicting meningioma consistency.

Purpose of the Study:

  • To evaluate the predictive value of T2-weighted imaging (T2WI) and apparent diffusion coefficient (ADC) histogram parameters for meningioma consistency.
  • To establish objective quantitative criteria for preoperative meningioma consistency assessment.

Main Methods:

  • Retrospective analysis of 103 meningioma patients' preoperative MRI and pathological data.
  • Calculation of T2WI and ADC histogram parameters using MaZda software.
  • Statistical comparison of histogram parameters between soft and hard meningiomas and assessment of predictive performance using ROC curves and logistic regression.

Main Results:

  • Tumor enhancement was the only conventional MRI feature differentiating soft from hard meningiomas.
  • Significant differences were observed in multiple T2WI and ADC histogram parameters between soft and hard meningiomas (P < 0.05).
  • Combined T2WI and ADC histogram parameters demonstrated high accuracy (AUC 0.873) in predicting meningioma consistency, with combined T2WI parameters being most effective.

Conclusions:

  • T2WI and ADC histogram parameters serve as valuable imaging markers for predicting meningioma consistency.
  • Combined T2WI histogram parameters offer superior predictive performance compared to combined ADC parameters.
  • These findings can aid in preoperative risk stratification and surgical planning for meningioma patients.
