PHPT: primary hyperparathyroidism; BMD: bone mineral density; DXA: dual-energy x-ray absorptiometry; CT: computed tomography; MRI: magnetic resonance imaging; VFA: vertebral fracture assessment; eGFR: estimated glomerular filtration rate; ISCD: International Society for Clinical Densitometry.
* Surgery is also indicated in patients for whom medical surveillance is neither desired nor possible and in patients opting for surgery, in the absence of meeting any indications, as long as there are no medical contraindications.
¶ Consistent with the position established by the ISCD, the use of Z-scores instead of T-scores is recommended in evaluating BMD in premenopausal women and men younger than 50 years.[1]Modified with permission from from: Bilezikian JP, Khan AA, Silverberg SJ, et al.
