NIRAF imaging to help parathyroid removal when preoperative tests don’t locate glands
Official title: Outcomes of Parathyroidectomy Using NIRAF-camera Versus Conventional Surgery in Patients With Preoperative Imaging Negative Primary Hyperparathyroidism: A Randomized Controlled Trial
Run by The Cleveland Clinic · NCT07812649 · Data updated 2026-11-12
This trial tests whether using an NIRAF camera during parathyroid surgery helps find and remove abnormal glands in people with primary hyperparathyroidism when prior imaging hasn’t pinpointed them.

Is this trial a fit for you?
✓Likely a good fit
Adults with primary hyperparathyroidism planned for bilateral neck exploration and parathyroidectomy.
✕Probably not a fit
Patients with secondary or tertiary hyperparathyroidism or those undergoing focal exploration or additional thyroid procedures may not benefit.

What this trial studies
This interventional study evaluates the use of near-infrared autofluorescence (NIRAF) imaging as an intraoperative aid for identifying parathyroid glands during bilateral neck exploration in primary hyperparathyroidism. Participants undergo parathyroidectomy guided by NIRAF in addition to standard preoperative imaging. The study focuses on whether NIRAF can improve gland identification when preoperative localization is negative or inconclusive. The trial is conducted at Cleveland Clinic with patients scheduled for parathyroidectomy and no additional concurrent neck procedures. Outcomes of interest include identification success, operative details, and short-term postoperative results.
Why it matters
Potential benefit: If successful, NIRAF guidance could improve gland identification and potentially increase cure rates or reduce operative time.
How similar studies have gone: Previous use of NIRAF in parathyroid procedures has shown promise for gland identification, though results vary and broader validation is ongoing.
