Abstract
Objectives: To optimize and enhance image quality and scan time of ankle MRI using a combined head coil and flex coil. Methods: Cross-sectional analysis of signal-to-noise ratio and inter-rater reliability in ankle MRI using various coil setups. Comparative study of single coil (head coil only), dual coil (head coil and flex coil), and dual coil combined the parallel imaging techniques for ankle MRI regarding image quality. The image quality was evaluated by two MSK radiologists using visual inspection following the Likert scale.
Results: Dual coil imaging demonstrated significantly higher signal-to-noise ratios than single coil imaging for sagittal T1-weighted, sagittal PD fat-suppressed, and axial PD fat-suppressed sequences (p < 0.05). Combining dual coils with parallel imaging further enhanced SNR for sagittal and axial PD fat-suppressed sequences than single coil (p < 0.05). The two radiologists had high inter-rater reliability in image visual assessment (K > 0.61).
Conclusions: The combined coil method demonstrated improved image quality and scanning duration compared to single coil imaging in ankle MRI.
