Abstract

Objectives: To describe the imaging characteristics of knee joint injuries using Deep Resolve and to evaluate the efficacy of this software in improving image quality of knee injuries on a 0.55 Tesla magnetic resonance imaging (MRI) system.


Subjects and Methods: A descriptive cross-sectional study with paired pre- and post-processing image comparisons was conducted. The study included 42 patients aged  18 years who were indicated for knee MRI due to trauma at Quang Ninh Provincial General Hospital.


Results: Following the application of Deep Resolve, the signal-to-noise ratio (SNR) significantly increased by 59,9% on T1W Coronal, 46,9% on T2W Sagittal, and 58.5% on PD FatSat Axial sequences (p < 0,001). The contrast-to-noise ratio (CNR) demonstrated respective improvements of 58,7% (T1W Coronal), 59,7% (T2W Sagittal), and 69,2% (PD FatSat Axial) (p < 0,001). Radiologists consistently evaluated the Deep Resolve-reconstructed images as having reduced image noise, enhanced sharpness, and superior overall diagnostic quality (p < 0,001). The inter-observer diagnostic agreement between the two radiologists was almost perfect, with a Cohen’s Kappa coefficient of 0,876.


Conclusion: The application of Deep Resolve significantly enhances image quality on a low-field 0.55T MRI system, demonstrated by improvements in both objective metrics (SNR, CNR) and subjective radiologist assessments.
