Abstract

We applied dual‐flex coils in a phased‐array configuration to obtain high resolution MR images of the bilateral hips and compared the image quality with non‐phased‐array imaging. Multiple fast spin‐echo images of both hips were obtained in a single acquisition. Two consecutive acquisitions with and without phased‐array capability were performed in 22 hips and a fluid‐filled phantom. The signal‐to‐noise ratio (S/N) enhancement values were calculated. Subjective image analysis was also obtained from three independent reviewers. High quality MR images were obtained using dual‐array coils with a S/N enhancement value of 1.40 for a phantom and 1.83 to 2.22 for subject hips. On subjective analysis, the dual array enhanced delineation of the acetabular labrum, articular cartilage, and retained fluid. The dual array may be of diagnostic value with a higher S/N enhancement and subjective superiority of the images obtained.
