[Current Possibilities of Using Radiopharmaceuticals to Evaluate Cerebral Blood Flow].

A comparison of the possibilities of using various neurotropic radiopharmaceuticals for scintigraphic evaluation of cerebral perfusion. In the whole range of radiopharmaceuticals used to diagnose cerebral blood flow disorders, there are Ceretec (99mTc-hexamethylpropyleneamine) and Neurolite (N,N-1,2-ethylenediylbis-L-cysteine-diethyl ether), which are the most optimal agents. Due to their high cost and related radiation exposure, the radiopharmaceuticals 123І-IMP (123I-isopropyl-iodoamphetamine) and 201Tl-DDC (diethyldithiocarbamate) labeled with thallium-201 virtually minimize the possibilities of being used in daily clinical practice.

[Scintigraphic assessment of alterations in cardiopulmonary haemodynamics and renal functional activity in patients with endured coronary artery bypass grafting].

Objective: By means of scintigraphic methods to assess alterations in cardiopulmonary haemodynamics and renal functional activity in patients with coronary artery disease (CAD) after endured coronary artery bypass grafting (CABG) performed in conditions of extracorporeal circulation (EC) and on the functioning heart.

Material And Methods: We examined a total of 40 patients presenting with CAD (mean age 54.90±1.

The usefulness of gated blood pool scintigraphy for right ventricular function evaluation in pulmonary embolism patients.

Objective: According to the international registry ICOPER, right ventricular (RV) dysfunction is the most significant predictor of mortality in patients with pulmonary embolism (PE).

Aim: To identify the most informative indicators of gated blood pool single photon emission computer tomography (GBP-SPECT) for evaluation of RV function in patients with PE.

Methods: A total of 52 patients were included in the study.

[Scintigraphic evaluation of impairments in cardiopulmonary hemodynamics and renal functional activity in patients with coronary heart disease and circulatory failure].

Objective: To evaluate the relationship between impairments in cardiopulmonary hemodynamics and renal functional activity in patients with circulatory failure, by applying radionuclide studies.

Material And Methods: Sixty-nine patients with coronary heart disease (mean age 53.23 +/- 0.

[Capabilities of radionuclide imaging study in the evaluation of pulmonary hemodynamics and right ventricular function in chronic obstructive pulmonary disease].

Objective: To assess the capabilities of radionuclide imaging studies in the evaluation of pulmonary hemodynamics and right ventricular function in chronic obstructive pulmonary disease (COPD).

Subject And Methods: Twenty-one patients aged 55.8 +/- 9.
