Higher field strength comes along with increase of the deposited SAR energy. Important imaging sequences like TSE with numerous refocusing pulses are only exercisable with limitations of the parameters at the expense of image quality to protect patients. In this work it is shown that it is possible to obtain high resolution in vivo images on a 7T scanner with an almost equal signal behavior in a combined acquisition technique (CAT) hybrid sequence consisting of a TSE module and an EPI module with SAR saving of 27%.
