7T MRI Phosphorus Imaging Protocol

All experiments used a Magnetom 7T scanner (Siemens, Erlangen, Germany).
Localizers were acquired with a 10 cm ¹H loop coil (Rapid Biomedical,
Rimpar, Germany). This was replaced by a T/R switch and preamplifier module
(Virtumed LLC, MN, USA) connected to a 10-cm ³¹P transmit–receive
loop coil (21 (link)) for the ³¹P
acquisitions. The ³¹P coil was tuned and matched using an RF sweeper
(Morris Instruments Inc, Ottawa, Canada) for each subject. All subjects in this
study were recruited in a manner approved by the local Research Ethics
Committee.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
