DOPA stability in plasma and plasma extracts.

Abstract

Unextracted heparinized plasma samples containing L-DOPA can be refrigerated or frozen with negligible losses in drug for at least two weeks. This stability of L-DOPA in the sample obviates difficulties in collection and processing of plasma samples within clinical settings which may be remote from the analytical laboratory facilities.

Role of [18F]-dopa-PET imaging in assessing movement disorders.

FD-PET has proved to be an extremely useful technique for the noninvasive evaluation of nigrostriatal pathophysiology in patients with PD and other movement disorders. The development of ratio methods for image analysis has greatly reduced the complexity of these PET studies and has facilitated data analysis. With the recent advances in cyclotron targetry and automated synthesis modules FD-PET will soon become an important component of the clinical armamentarium.

Carcinoid crisis after injection of 6-18F-fluorodihydroxyphenylalanine in a patient with metastatic carcinoid.

A carcinoid crisis is a severe complication of the carcinoid syndrome that can arise in patients with advanced metastatic neuroendocrine tumors. It can be initiated by stress, catecholamines, and tumor manipulation. In this article, we report a case in which an injection with the catecholamine tracer 6-18F-fluorodihydroxyphenylalanine, used for PET, induced a carcinoid crisis. Octreotide can be used for treatment and should be available. Tracer injection should be slow.
