MR technology is evolving at a rapid pace, fostering the use of higher field strength magnets that will improve the resolution of additional compounds using MRS, and higher resolution of brain structures imaged with T1- and T2-based methods. The development of higher strength gradients has enabled improved signal to noise for DTI studies. Smaller coils, and coils utilizing phased-array acquisitions permit faster and higher resolution acquisitions without the need to go to higher field strength. Additional advances in software and hardware development have introduced methods to correct for head movement during scanning, which will greatly improve the quality of data derived from younger subjects, particularly those who may be unable to stay still for long periods of time, as is evident in a subset of drug exposed children.
