[Abstract] Objective To analyze the image quality, scan time and clinical application of 3D hip MRI accelerated with compressed sensing (CS), comparing with the traditional multi-directional 2D hip scan protocols.Materials and Methods Twenty-two patients were enrolled in the study based on clinical diagnosis. Traditional hip scan protocol include: 2D coronal and 2D axial proton density-spectral attenuated inversion recovery (PD-SPAIR) weighted imaging, 2D coronal T1 weighted imaging (T1WI), 2D axial T2 weighted imaging (T2WI). Advanced hip scan protocol include: 3D axial PD-SPAIR sequence with 6-fold CS acceleration, 2D coronal T1WI, 2D axial T2WI. Signal to noise ratios (SNR) and contrast-noise-ratios (CNR) were calculated and compared for the femoral head. The subjective evaluation and scan time were compared between two protocols.Results The subjective score of 2D PD-SPAIR and 3D PD-SPAIR images were range from 20-22 (P>0.05) with high consistency between two doctors (kappa=0.636, P=0.002). All images satisfied the clinical needs. The SNR of the femoral head in 2D PD-SPAIR was significantly higher than that in the 3D PD-SPAIR group (P=0.001). There was no significant difference of CNR between two sequences. The scan time of the advanced protocol which include CS (median 513 s) was significantly shorter than that of the traditional one (median 603 s) (P<0.001).Conclusions The introduction of 3D CS sequence can not only present multi-directional display with anatomy details, but may also improve the efficiency, success rate and examination experience of children's hip MRI scan, which could be conducive to optimized pediatric MRI scan process.
