Patient group	Sensitivity/specificity	SPECT/CT	SPECT/CT with pinhole	p
All patients	Sensitivity	94%	97%	NS
	Specificity	98%	99%	NS
Primary hyperparathyreosis	Sensitivity	95%	98%	NS
	Specificity	98%	99%	NS
Secondary hyperparathyreosis	Sensitivity	89%	94%	NS
	Specificity	100%	100%	NS

NS indicates not statistically significant.
