The aim of this study was to investigate the effect of magnetization transfer on multislice T1 and T2 measurements of articular cartilage. 
\nMaterials and Methods 
A set of phantoms with different concentrations of collagen and contrast agent (Gd-DTPA2-) were used for the in vitro study. A total of 20 healthy knees were used for the in vivo study. T1 and T2 measurements were performed using fast-spin-echo inversion-recovery (FSE-IR) sequence and multi-spin-echo (MSE) sequence, respectively, in both in vitro and in vivo studies. We investigated the difference in T1 and T2 values between that measured by single-slice acquisition and that measured by multislice acquisition. 
\nResults 
Regarding T1 measurement, a large drop of T1 in all slices and also a large interslice variation in T1 were observed when multislice acquisition was used. Regarding T2 measurement, a substantial drop of T2 in all slices was observed; however, there was no apparent interslice variation when multislice acquisition was used. 
\nConclusion 
This study demonstrated that the adaptation of multislice acquisition technique for T1 measurement using FSE-IR methodology is difficult and its use for clinical evaluation is problematic. In contrast, multislice acquisition for T2 measurement using MSE was clinically applicable if inaccuracies caused by multislice acquisition were taken into account.},
