[Echography and integrated imaging in the diagnosis of hyperparathyroidism].
The authors report their personal experience with US, CT, biopsy and, lately, MRI, to localize enlarged parathyroid glands in primary and secondary hyperparathyroidism. December 1986 through December 1993, sixty-four primary and 55 secondary hyperparathyroidism patients were examined--119 in all. At biopsy and surgery, US sensitivity appeared to be 72%, with 0.94 positive predictive value; CT sensitivity was 80% with 0.91 positive predictive value. The two methods combined had 87% sensitivity in all. In the authors' experience, US proved to be a sensitive, accurate and cost-effective technique, as well as the best method to guide biopsy thanks to its multiplanar capabilities. Even though it requires great operator's experience, US is the method of choice in the localization of abnormal parathyroid glands. Its combination with CT increased overall sensitivity mainly in ectopic localizations and postoperative recurrences. Finally, technologic progress and increased MR sensitivity are likely to make MRI the imaging technique of choice, replacing CT, in the diagnostic protocol of hyperparathyroidism.
