MRI detects pituitary microadneomas in 50% of cases. Transsphenoidal surgery allows placement of an MRI receiver coil within the sphenoid, dramatically improving SNR. A 12 mm diameter 1.5 T interventional pituitary surface coil (IPSC) was prototyped. The IPSC was positioned using the transsphenoidal approach in two cadaveric heads. The SNR gain with the IPSC was 5-10 fold compared to the 8-channel head coil. Structures visible using IPSC included the pituitary capsule, intercavernous sinus, and medial wall of the cavernous sinus. This novel coil may become an important intraoperative tool for transsphenoidal surgery.
