Multi-scanner repeatability and reproducibility of qRF-MRF breath-held and free-breathing with pilot tone in the abdomen

Puntos clave

Findings indicate strong repeatability and reproducibility across different scanning conditions, ensuring reliable imaging.
Results demonstrate limits of agreement and bias estimations for qRF-MRF sequences, emphasizing their diagnostic potential.
Evaluation utilized Bland-Altman analysis to compare breath-held and free-breathing qRF-MRF imaging techniques.
These findings may enhance clinical outcomes by providing accurate imaging for prognosis and treatment decisions.

Resumen

Using Bland-Altman analysis, our results for T1, T2, and T2* establish the repeatability and reproducibility, via the limits of agreement and bias estimations, of the FB qRF-MRF sequence and compare to its breath-held qRF-MRF and clinical standard counterparts across scanners and scan conditions. DISCUSSION: Based on the bias and limits of agreement of breath-hold and FB qRF-MRF patients can receive reliable and comparable imaging at different sessions for prognosis and treatment planning.
