In Reply We thank Collins et al for their interest in our work.1 In their letter, Collins et al point to the discordance rate of 29.9% we reported for parathyroid 4-dimensional computed tomography (4D-CT) as the preoperative localization modality for primary hyperparathyroidism.1 This was compared against the authors’ published data2 of 91% accuracy using a combination of ultrasonography and technetium 99m sestamibi-labeled single-photon emission computed tomography/computed tomography (SPECT/CT).
