To investigate the relevance of lesion size in liver DWI concerning missed lesions and contrast-to-noise ratio (CNR) between navigator-triggered (TRIG) and free-breathing (FB) acquisition techniques, emphasizing their clinical implications.
Key Findings:
TRIG acquisition detected more small FLLs compared to FB acquisition, indicating its potential advantage in clinical settings.
Lesion detection and characterization abilities were similar between TRIG and FB, but TRIG provided better image quality, which may enhance diagnostic confidence.
Discrepancies in previous studies may be attributed to variations in lesion sizes, highlighting the need for standardized assessment.
Interpretation:
TRIG acquisition may be more effective for detecting smaller liver lesions, while FB acquisition offers time efficiency without significant loss in detection capabilities, underscoring the importance of technique choice in clinical practice.
Limitations:
Study focused on a limited patient population and specific lesion sizes, which may limit the applicability of the findings to broader clinical scenarios.
Potential biases in lesion characterization due to subjective assessments, necessitating further validation.
Conclusion:
The choice between TRIG and FB acquisition techniques in liver DWI should consider lesion size, with TRIG being preferable for smaller lesions, which is crucial for accurate diagnosis and treatment planning.
With its combination of UWF imaging, OCT integration, and intelligent review tools, the MonacoPro represents the next step in comprehensive retinal evaluation. By improving image quality, enhancing diagnostic confidence, and streamlining workflow, the system supports clinicians in delivering more efficient, informed, and patient-centered care.
