Work in progress: abnormal parathyroid glands. Comparison of nonselective arterial digital arteriography, selective parathyroid arteriography, and venous digital arteriography as methods of detection.

abstract：:In a series of nine stereotaxic large-core biopsies of calcifications, radiography of the specimen was used to ensure that appropriate tissue was removed. In eight cases, calcifications were evident at radiography as well as at histologic evaluation. Four cases were malignant and four were benign, and in one case in w...
