The purpose of this study was to evaluate prospectively the reliability of the new nonspecific tumor-searching tracer tetrofosmin in the postoperative follow-up of differentiated thyroid carcinoma (DTC) during TSH suppressive thyroid hormone treatment. ⋯ Technetium-99m-tetrofosmin is a promising tracer to detect malignant recurrence and distant metastases in the follow-up of DTC without the necessity of thyroid hormone withdrawal.

Effect of beta 1 adrenergic receptor blockade on myocardial blood flow and vasodilatory capacity.
The beta 1 receptor blockade reduces cardiac work and may thereby lower myocardial blood flow (MBF) at rest. The effect of beta 1 receptor blockade on hyperemic MBF is unknown. ⋯ The beta 1 receptor blockade increases coronary vasodilatory capacity and myocardial flow reserve. However, the mechanisms accounting for this finding remain uncertain.
