Monte-Carlo simulations with spatially varying coil sensitivities and varying levels of complex Gaussian noise were performed while using R=1 SENSE and SoS for coil combination and generating T2 maps. (a) For low SNR values typically seen with meniscus (T2 about 12ms), SoS significantly overestimates the estimated T2. (b) For higher SNR typically seen with cartilage (T2 about 30ms), SENSE and SoS have comparable T2 estimates.
