We reviewed nuclear endocrinological examinations of the thyroid, parathyroid, and adrenal glands that are clinically performed in Japan as well as somatostatin receptor imaging, which is widely used in Europe, the United States, and other countries. 123I thyroid scintigraphy is especially useful in detecting ectopic goiters and differentiating between Basedow's disease and subacute thyroiditis or Plummer's disease, all of which exhibit thyrotoxicosis. 201Tl is useful to detect foci metastasized from well differentiated thyroid cancer and to differentiate malignant from benign tumors. 67Ga-citrate is an agent used for patients suspected of having malignant lymphoma or undifferentiated carcinoma of the thyroid. Radioiodinated MIBG is a specific agent for medullary thyroid carcinoma. 99mTc-MIBI is a good agent for locating hyperfunctioning parathyroid tissues. 131I-adosterol is useful to locate the lesions of primary aldosteronism, Cushing's syndrome, adrenogenital syndrome, and select adenomas among incidental tumors. Radioiodinated MIBG scintigraphy has high diagnostic accuracy in locating pheochromocytomas and neuroblastomas. 111In-labeled octreotide is useful in locating, hormone-producing gastrointestinal and pancreatic tumors including carcinoids, gastrinomas, and insulinomas. Radiolabeled somatostatin receptor analogs are used not only to locate but also to treat malignant somatostatin receptor-positive tumors. We hope that Octreoscan will be available in Japan in the near future.

CLINICAL EVALUATION OF SCINTIGRAPHY AND TUMOR BIOPSY FOR INCIDENTALY DETECTED ADRENAL MASSES

Article

作者: Ukimura, O ; Kojima, M ; Watanabe, H ; Ochiai, A ; Inui, E

PURPOSE:

A decision tree in diagnosis of incidentally detected adrenal masses (incidentaloma) was made on the basis of these results.

METHODS:

The clinical usefulness of adrenal scintigraphy with 131I-adosterol and ultrasonically guided tumor biopsy was investigated in 44 patients.

RESULTS:

Adrenal scintigraphy was performed in 32 patients, of whom 21 were found to have an increased uptake in the tumor, including 19 cases of cortical adenoma and 2 of hematoma. No abnormal uptake was found in the remaining 11 patients, including 2 of cortical adenoma, 1 of adrenocortical oncocytoma and 8 of non-cortical tumors. Adrenal scintigraphy was thus thought to be useful in the differentiation of cortical tumor from non-cortical tumor, showing the sensitivity of 86%, the specificity of 80% and the diagnostic accuracy of 84%. Cytological or histological study on specimens obtained by percutaneous adrenal tumor biopsy was performed in 19 patients, of whom 18 (95%) were correctly diagnosed in terms of the malignancy of incidentaloma.

CONCLUSIONS:

Taken together, the differential diagnosis and the surgical indication of adrenal incidentaloma could be made successfully based on adrenal scintigraphy and tumor biopsy.

Comparative study of image diagnosis of ultrasonography (US) by linear electronic scanner, computed tomography (CT), and adrenal scintigraphy was performed in 14 patients with Cushing's syndrome. Adrenal imaging by scintigraphy was performed at the 5th and 6th day or further 7th day following the injection of 1 mCi of Adosterol. Cushing's disease (11 cases) US failed to detect the adrenals in 4 cases examined. Measurement of the adrenals on CT film demonstrated the enlargement of adrenals (greater than mean + 2SD) in 6 of 7 cases (85.7%). Scintiscanning showed the increased uptake of bilateral adrenals in 4 of 10 cases (40%). Adrenal scintigraphy with dexamethasone pretreatment (DP) still demonstrated the isotope uptake of bilateral adrenals in all of those 4 cases tested, although the other 6 cases were not studied with DP. From these findings, it was suggested that the measurement of adrenal size by CT was useful for the additional image diagnosis of Cushing's disease, and the adrenal scintigraphy with DP was also available for complementary study of Cushing's disease. Cushing's syndrome due to adrenocortical adenoma (3 cases) In one case examined by US, which had the smallest adenoma (0.6 X 1.0 X 2.0 cm) in this syndrome, the adenoma was not detected. All of 3 adrenal adenomas (2.6 X 2.6 X 2.2 cm to 0.6 X 1.0 X 2.0 cm) were detected by CT. Adrenal scintigraphy demonstrated good uptake by adrenal adenoma but no visualization of the contralateral adrenal in every case.
