EXPERIENCE WITH PARATHYROID SCINTIGRAPHY

Parathyroid scintigraphy.

Scintigraphy of the parathyroid glands continues to be controversial from several standpoints, including radiopharmaceutical choice, imaging protocol, results, and utility in clinical situations. This article reviews: the anatomy, physiology and pathology of the parathyroid glands; mechanisms of radiopharmaceutical localization; commonly accepted imaging protocols; image results; and the approp...

Thyroid and parathyroid scintigraphy

Parathyroid 4D CT and Scintigraphy

Objective. To determine the prevalence of missed lesions for parathyroid 4-dimensional computed tomography (4D CT) and scintigraphy and to describe the factors leading to missed lesions for both modalities. Study Design. Case series with chart review. Setting. Single center, hospital based. Subjects and Methods. Forty patients undergoing 4D CT and scintigraphy before parathyroidectomy between J...

Absent radiotracer uptake in thyroid gland in parathyroid scintigraphy with 99mTc-MIBI: A case report

Localization of 99mTc- hexakis-2-methoxyisobutylisonitrile (99mTc-MIBI) by parathyroid adenomas is well known, and this warrants MIBI scan to evaluate suspected parathyroid adenoma in primary hyperparathyroidism. Typically, the radionuclide concentrates in both the thyroid gland and parathyroid adenoma in early images, and later on delayed images washes out slowly from the...

Significance of MIBI scintigraphy in a patient with hydatid cyst and parathyroid adenoma

A 17-year-old boy with hyperparathyroidism exhibited a large cyst in the left hemi-thorax on his chest X-ray. The cyst was identified as a hydatid cyst. He was referred for biphasic methoxy isobutyl isonitrile (MIBI) parathyroid scan. A discrete ectopic parathyroid was detected in the left upper mediastinum in addition to accumulation of the MIBI tracer in the cyst wall. Using radio-guided occu...
