In plain words

What the trial is, and whether it could suit you

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.

📋 Eligibility rules (as published)
For Contrast Based Protocol: Inclusion Criteria: * Diagnosis of Cushing disease or required resection for non-corticotroph adenomas * Agree to transsphenoidal resection. Exclusion Criteria: * Patients who are unable to consent (or if their legal guardian/representative decline to consent) * Patients who have known or suspected hypersensitivity to microbubble contrast agents or its components such as polyethylene glycol (PEG). * Women of child-bearing potential with a positive pregnancy test prior to procedure. * Patients who have right to left, bi-directional, or transient right to left cardiac shunts. * Patients who have hypersensitivity to perflutren. For Non-Contrast Based Protocol: Inclusion Criteria: * Patients undergoing any pituitary surgery with the study designated neurosurgeons. * Patients whose procedures require the use of an intra-operative BK ultrasound without contrast. Exclusion Criteria: • Patients who are unable to consent (or if their legal guardian/representative decline to consent)
