Anagrelide is a member of the imidazo (2,1-b) quinazolin-2-one series compounds, with powerful antiaggregating effect on platelets. During studies in humans, anagrelide small doses has produced thrombocytopenia. We therefore evaluated it treatment thrombocytosis, and to date, platelet levels 15 17 patients primary thrombocythemia, 2 polycythemia vera 1 patient chronic granulocytic leukemia thrombocytosis have been well controlled use this agent.

Describes a general method for the measurement of radioactivity in an organ using anterior, posterior and lateral views. Its application to liver colloid imaging is described as liver/spleen ratio widely used indication cirrhosis.
A technique is described for using computed tomography (CT) images attenuation correction and quantification in SPECT. The CT are aligned with the corresponding SPECT slices Hounsfield units converted to linear coefficient values radionuclide. map thus produced used provide required reconstruction. has been evaluated both a non-anatomical an anatomical phantom giving mean accuracy quantifying activity of various features phantoms 2.6% (range 0.3%-4.0%). value performing scatter prior...
A novel gamma-ray camera is proposed that based on the Compton effect. The basis of device a segmented semiconductor detector which able to locate successive interaction points in multicollision trajectories and associated energy losses. In this way, conic section can be computed an image plane for each emission from point source object. An overall constructed by summation individual ellipses. effect measurement errors investigated theoretically simulation, leads favourable estimates...
Two-dimensional (2D or planar) imaging with (99m)Tc radiolabels enables quantification of whole-lung and regional lung depositions for orally inhaled drug products. This article recommends standardized methodology 2D studies. Simultaneous anterior posterior a dual-headed gamma camera is preferred, but single-headed also acceptable. Correction raw data the effects ray attenuation considered essential accurate quantification, instance, using transmission scanning flood-field source (57)Co....

Abstract Clinical research on the deposition of inhaled substances (e.g. medications, airborne contaminants, fumes) in lungs necessitates anatomical models airways. Current conducting airway lack three‐dimensional (3D) reality as little information is available literature distribution airways space. This a limitation to assessment or predictions particle relation subject’s anatomy. Detailed full topology and morphology thus required model tree realistically. paper presents length, diameter,...
Summary Conventional creatinine clearances involving urine collections over 2, 4 and 24 hours clearance predicted from plasma concentrations without collection were compared to glomerular filtration rate (GFR) estimated by 99mTc DTPA in 171 patients with a wide range of GFR. All methods had standard errors the estimate GFR greater than predictions formulae. Predictions formulae coefficients variation approximately 23% when isotopically determined Creatinine these equations stable renal...
