Evaluation of Intraoperative Contrast Enhanced Ultrasound for the Identification of Pituitary Adenoma in Cushing's Disease Compared to Other Pituitary Tumors
Recruiting now
Conditions studied: Pituitary Adenoma, Cushing Disease
In brief
This pilot and feasibility study aims to combine recent advances in ultrasound imaging, specifically an endonasal transducer array and contrast enhanced ultrasound, to offer an intraoperative image-guided solution for lesion-specific surgical resection to impact clinical outcome. Should this imaging approach help isolate specific lesions and prevent surgical resection of normal pituitary tissue in this first-in-humans study, then the results will provide clinical data for a much larger multi-center clinical trial.
