Key result
Dynamic optical contrast imaging differentiates hypercellular parathyroid glands from surrounding tissues with 100% sensitivity.
Why the study?
Intraoperative identification of hypercellular parathyroid glands during surgical excision for primary hyperparathyroidism can be challenging due to variable location and indistinct features.
Does dynamic optical contrast imaging (DOCI) accurately identify and differentiate hypercellular parathyroid glands from surrounding tissues in ex-vivo specimens?
Does dynamic optical contrast imaging (DOCI) accurately identify and differentiate hypercellular parathyroid glands from surrounding tissues in ex-vivo specimens?
Dynamic optical contrast imaging demonstrates high sensitivity and specificity for differentiating hypercellular parathyroid glands ex-vivo, suggesting potential utility for intraoperative guidance.

DOCI may aid ex-vivo parathyroid identification; hypothesis-generating and requires human trials before clinical consideration.
Surgical excision of an adenomatous or hypercellular parathyroid gland is typically the treatment of choice for primary hyperparathyroidism. Intraoperative identification can be challenging due to potential variable location and indistinct features of these glands. In 115 ex-vivo specimens we evaluated the efficacy of DOCI in identifying hypercellular parathyroid glands. Significant imaging differences were seen between hypercellular vs normal parathyroid glands vs other adjacent healthy tissues across 8 spectral channels (p<0.05). Our classification result (100% sensitivity, 98.8% specificity) using a logistic regression classifier further corroborated that DOCI has the capacity to accurately identify and differentiate parathyroid glands from surrounding tissues. DOCI enables sensitive and specific mapping of parathyroid location, leading to improved accuracy of the surgical procedure, reduced time to successful completion, fewer risks and improved patient outcomes.
