Comparison of commercial 1Tx32Rx vs. 8Tx32Rx head coils for routine 7T neuroimaging

Christopher T. Rodgers
IntroductionHuman 7T MRI systems are manufactured by three vendors (Siemens, Philips, and GE) who all provide equivalent head coils from the same 3rd party manufacturer. Furthermore, many 7T MRI sites have two head coils available for neuroimaging: a 1Tx32Rx head coil for conventional single-channel transmit imaging and an 8Tx32Rx head coil for parallel-transmit (pTx) imaging.MethodsWe compared the performance of these coils in six healthy volunteers. All scans were done on a 7T MRI (MAGNETOM Te
