In the present study we evaluated the binding of the radiopharmaceuticals sodium pertechnetate (Na 99mTcO4), methylenediphosphonic acid (99mTc-MDP) and glucoheptonate acid (99mTc-GHA) to blood elements using centrifugation and radioautographic techniques. Heparinized blood was incubated with the labelled compounds for 0, 1, 2, 3, 4, 6 and 24 h. Plasma (P) and blood cells (BC) were isolated and ...
Introduction: A noninvasive method of detecting exposure of phosphatidylserine (PS) on the external surface of the plasma membrane such as nuclear imaging could assist the diagnosis and therapy of apoptosis related pathologies. The most studied imaging agent for apoptosis is Annexin V so far. Because of limitations of Annexin V other agents have been introduced such as small peptides and molecu...
CONTEXT Inherited and sporadic medullary thyroid cancer (MTC) is an uncommon and medically challenging malignancy. Even if the extent of initial surgery is deemed adequate, the recurrence rate remains high, up to 50% in most series. Measurement of serum calcitonin is important in the follow-up of patients with MTC, and reliably reflects the existence of the disease. EVIDENCE ACQUISITION There...

Background: Skeletal uptake of 99mTc labelled methylene diphosphonate (99mTc-MDP) is used for producing images of pathological bone uptake due to its incorporation to the sites of active bone turnover. This study was done to validate bone turnover markers using total skeletal uptake (TSU) of 99mTc-MDP. Methods: 22 postmenopausal women (52–80 years) volunteered to participate. Scintigraphy was p...
BACKGROUND Annexin A5 (anxA5) has been found useful for molecular imaging of apoptosis and other biological processes. METHODS Here, we report an optimised two-step synthesis of annexin A5-diethylene triamine pentaacetic acid (DTPA) (anxA5-DTPA) for positron emission tomography (PET) and single-photon emission computed tomography (SPECT) imaging with a single purification step. The use of a r...
