Oscillating Gradient Diffusion-Weighted MRI in diagnosing cervical cancer and evaluating the degree of pathological differentiation

Key Points

ADC33 Hz shows superior performance in detecting cervical cancer differentiation, achieving an AUC of 0.96.
Sensitivity rates reached 85.71% while specificity was reported at 96.15% during diagnosis detection.
Research utilized 3 T MRI with oscillating and pulsed gradient sequences for data collection on cervical cancer patients.
Findings highlight the potential of advanced MRI techniques in improving diagnostic accuracy for cervical cancer.

Abstract

Motivation: Oscillating gradient diffusion-weighted imaging (DWI) enables elucidation remains underexplored in the pathological differentiation of cervical cancer. Goal(s): To investigate the application value of parameters derived from Oscillating Gradient Diffusion-Weighted MRI (ADCPGSE, ADC17Hz, ADC33Hz) in the pathological differentiation of cervical cancer. Approach: We collected 3 T MRI including DWI using oscillating gradient spin-echo (OGSE) and pulsed gradient spin-echo (PGSE) research sequences from cervical cancer patients, comparing the respective parameters' efficacy in pathological differentiation. Results: ADC33 Hz outperformed ADCPGSE in cervical squamous carcinoma and Healthy subjects, with combined parameters yielding an AUC of 0.96, sensitivity of 85.71%, and specificity of 96.15% for diagnosis detection. Impact: This study confirms the advantages of Oscillating Gradient Diffusion-Weighted MRI parameters in the pathological differentiation of cervical cancer, especially for diagnosing cervical cancer, offering greater accuracy than traditional ADCPGSE.
