Objective:This paper discussed the feasibility and clinical value of adaptive image re-ception(AIR)coil in supine breast magnetic resonance imaging.Methods:A total of 53 patients who underwent MRI examination were included.AIR coil was used during supine MRI examination,and im-age quality was compared with that in prone position,including image signal-to-noise ratio(SNR),contrast-to-noise ratio(CNR),contrast ratio(CR),artifact,sharpness and overall score.The display a-bility of lesions was evaluated,and the SNR,CNR and edge definition of lesions in different body posi-tions were compared.The maximum length diameter of the lesion and the distance between the lesion and the midpoint of the nipple and sternum were recorded and measured.Results:The CR of T2 images in supine position was higher than that in prone position(0.59±0.02 vs.0.54±0.01),and the SNR of fat in diffusion weighted image supine position was higher than that in prone position(12.08±2.95 vs.9.31±0.91).In T2 images,the signal-to-noise ratio of the lesion in supine position was higher than that in prone position(120.41±31.86 vs.34.25±4.60),and the distance from the lesion to the midpoint of the sternum in supine position was larger than that in prone position(113.99±2.03 vs.86.64±2.14),with statistical significance(P＜0.05).There was no significant difference in artifacts,sharpness and overall score between supine and prone images.The edge definition of lesions showed no statistical difference between the two positions.Conclusion:This study verified the feasibility of AIR coil in su-pine breast MRI.The use of AIR coil result in the similar image quality between supine and prone po-sition,which is worth for clinical use.
