[Abstract] Objective To evaluate the feasibility and imaging performance of a self-developed transportable magnetic resonance imaging detection array (TMRDA) for multi-site imaging of human body.Materials and Methods Phantom studies were performed to compare the magnetic resonance imaging (MRI) performance of 24-channel TMRDA against two commercial coils: a 24-channel head and neck combined coil and a 24-channel abdominal coil. Subsequently, 34 healthy volunteers underwent standardized scans (brain, liver, and hip) using both systems. Quantitative metrics including signal-to-noise ratio (SNR), uniformity, percent signal ghosting, contrast-to-noise ratio (CNR), contrast ratio (CR), and MRI quantitative parameters were evaluated. Two radiologists performed subjective image quality assessments.Results In phantom studies, TMRDA demonstrated significantly superior SNR and uniformity on both T1-weighted imaging and T2-weighted imaging compared to commercial coils (P < 0.001), with comparable or better percent signal ghosting. Volunteer studies showed TMRDA achieved significantly higher SNR and CNR across all anatomical regions (P < 0.001) with equivalent or better CR. No significant differences were observed in quantitative MRI parameters or subjective image quality scores (P > 0.05).Conclusions The TMRDA achieves comparable or superior image quality to dedicated commercial coils for brain, liver, and hip MRI examinations, demonstrating significant clinical utility for multi-site applications while maintaining diagnostic confidence.
