Preliminary Study Concerning the Validity of Parathyroid Exploration on a CZT Camera

Preliminary Study Concerning the Validity of Parathyroid Exploration on a Discovery NM 530c CZT Camera

The goal of this study is to assess the performance of parathyroid imaging on a cardiac-dedicated CZT camera, compared to planar pinhole imaging, in patients referred for primary hyperparathyroidism.

The goal is to determine if parathyroid tomoscintigraphy on a CZT camera can provide at least equivalent diagnostic performance, compared with planar pinhole imaging.
