Diagnostic performance of a single breath-hold lung MRI scan with AI-powered compressed sensing for nodule detection in comparison to photon counting detector-CT
To assess the diagnostic sensitivity of a lower-resolution AI-CS 3D-T1-FFE 3-T MRI protocol for detecting pulmonary nodules, entirely acquired during a single breath-hold, using photon-counting detector CT (PCD-CT) as the standard of reference.
Approach:
MRI and CT Protocols: MRI was performed on a 3-T system with a 2 mm isotropic spatial resolution. PCD-CT was conducted during end-inspiration breath-hold using a low dose protocol, with specific parameters detailed in the source.
Key Findings:
AI-CS MRI allows for faster scans while maintaining image quality.
Single breath-hold acquisition reduces motion artifacts and improves patient compliance.
PCD-CT serves as the reference standard for nodule detection.
Interpretation:
Limitations:
Single-center study may limit generalizability.
Exclusion of patients with interstitial lung disease or inflammatory alterations.
Conclusion:
The study evaluates a novel approach to lung MRI that could enhance nodule detection.
