Correlation between multi-parameter MRI and Gleason score in prostate cancer using point-to-point irradiation analysis

Puntos clave

Clinically significant prostate cancer can be identified through specific MRI measurements, enabling better diagnosis.
T2WI, DWI, and ADC ratios are effective in correlating with the Gleason score, improving diagnostic accuracy.
MRI scans facilitate a noninvasive approach to diagnosing prostate cancer, reducing reliance on invasive biopsies.
The proposed parameter enhances the ability to detect prostate cancer without the complications of traditional biopsy methods.

Resumen

Motivation: Prostate cancer biopsy is invasive and may be influenced by sampling errors, causing abnormalities visible on MRI to be overlooked. Goal(s): To propose a quantitative parameter for prostate cancer diagnosis. Approach: Patients underwent 3T MRI scans. Prostate cancer diagnosis was confirmed by outlining regions of interest on T2-weighted imaging (T2WI), diffusion-weighted imaging (DWI), and apparent diffusion coefficient (ADC) maps. Ratios for T2WI, DWI, and ADC values were calculated; Gleason score served as the reference standard. Results: Clinically significant prostate cancer can be identified and differentiated by measuring T2WI ratios, DWI ratios, and ADC values specific to prostate cancer. Impact: The proposed quantitative parameter, based on prostate cancer/obturator internus muscle signal intensity, enables noninvasive prostate cancer diagnosis and eliminates the need for biopsy.
