Intraoperative Scintigraphy Using a Large Field-of-View Portable Gamma Camera for Primary Hyperparathyroidism: Initial Experience

Table 3

Contingency table of imaging findings versus pathology findings for excised specimens and neck imaging.

Specimen imaging versus pathology			Postexcision neck imaging versus pathology
	Pathology positive	Pathology negative		Pathology positive	Pathology negative
Specimen imaging positive	20	0	Neck imaging residual focus	20	0
Specimen imaging negative	0	7	Neck imaging focus gone	0	7
True positives for specimen imaging (specimen hot adenoma removed)					=100%
True positives for neck imaging (focus present adenoma not removed)					=100%
False positives for specimen imaging (specimen hot adenoma not removed)					=0%
False positives for neck imaging (focus present adenoma removed)					=0%
True negatives for specimen imaging (specimen cold adenoma removed)					=100%
True negatives for neck imaging (focus absent adenoma removed)					=100%
False negatives for specimen imaging (specimen cold adenoma not removed)					=0%
False negatives for neck imaging (focus absent adenoma not removed)					=0%
