Reappraising the Diagnostic Accuracy of Post-Treatment Whole-Body Scans for Differentiated Thyroid Carcinoma.

Initial treatment for differentiated thyroid carcinoma (DTC) often consists of surgery and the administration of radioiodine. In this context, post-treatment Whole-Body Scans (ptWBS) are currently recommended, but data on its diagnostic accuracy are rare. The aim of the study was to evaluate the performance of ptWBS for distant metastasis in DTC patients.

Abnormal captopril scintigraphy in Bartter syndrome.

A 37-year-old patient with severe hypokalemia (approximately 1.7 mEq/L) and muscular weakness had a very high serum renin level. No renin-producing tumor was found and she was diagnosed with Bartter Syndrome The parathyroid hormone level was high due to concomitant renal calcium loss.

[The use of helium-oxygen mixture in the ventilation study of children with chronic obstructive lung disease].

OBJECTIVE: To study the distribution of Tc-99m DTPA radioaerosol when heliox or oxygen are used in the nebulization of children and adolescents with chronic obstructive pulmonary disease during pulmonary ventilation scintigraphy. MATERIAL AND METHODS: Clinical randomized and controlled trial. Patients with chronic obstructive pulmonary disease (5 to 18 years old) who required pulmonary scintigraphy between March 1996 and September 1998 were included.
