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%.
