TABLE 1.

Performance of Different ^99mTc-MIBI Parathyroid Planar Scintigraphy Protocols in Secondary Hyperparathyroidism

	Tracers Used	Pinhole Collimator	Studies/Patients/Number of Lesions^*	Sensitivity (%)^*
A	^99mTc-MIBI only “dual-phase”	No	15/308/899	56.2 (505/899)
B	^99mTc-MIBI only “dual-phase”	Yes	4/60/196	63.2 (124/196)
C	^99mTc-MIBI + ¹²³I (simultaneous acquisition plus subtraction)	Yes	2/31/126	75.4 (95/126)
D	^99mTc-MIBI + ^99mTcO₄ (non-simultaneous)	No	2/51/178	51.7 (92/178)
E	^99mTc-MIBI + ^99mTcO₄ (non-simultaneous)	Yes	1/21/78	62.8 (49/78)

Comparison between imaging protocols were performed using chi-squared test: A vs. B (P = 0.082); A vs. C (P < 0.001); B vs. C (P = 0.031).

Data were extracted from Tables 1 to 3 of the paper published by Caldarella,³³ and sensitivity was calculated based on these data.
