The method for planar image dosimetry was based on a two-compartment approach that separated the high uptake area from the low uptake area in geometric mean images produced from the anterior and posterior whole-body images.
The main uptake area was Berlin and the north-eastern districts of Germany with a population of 7,600,000.
High resolution scans produced by LaBr3 Ce camera showed higher tumor contrast with a detailed imaging of uptake area than pixellated NaI(Tl) dedicated camera.
The ratio of 125I-TNC-Ab uptake ROI area to an ischemic ROI area was defined as the percentage of the 125I-TNC-Ab uptake area.
Dopaminergic terminals are present at high density in the striatum but are less dense in the cerebellum, which makes delineation of the nonspecific uptake area very difficult.
125I-TNC-Ab uptake area was also set manually as a ROI by circumscribing the increased activity of the 125I-TNC-Ab.
Regions of interest (ROI) were manually drawn around the focal 68Ga-RGD uptake area in the myocardium on a transverse image, corresponding to 13N signal loss.
The 99mTc-annexin-V uptake ratio was calculated by dividing the uptake value of the 99mTc-annexin-V uptake area by that of the normally perfused area.
The nanofiltration performances in terms of solvent uptake, area swelling, solvent flux, and solute rejection of the membranes are systematically investigated using four commonly-used solvents, including ethanol, acetone, ethyl acetate, and n-heptane.
Membrane morphology and properties, including ion exchange capacity, water uptake, area resistance, tensile strength and transport number, have been characterized to determine advantages of this strategy over the post-modification method.
The size of the focal uptake area in the autoradiogram sections was comparable between the three groups (8.2 ± 5.1; 7.3 ± 3.2 and 7.4 ± 4.5 mm2 for 18F-galacto-RGD, 68Ga-NODAGA-RGD and 68Ga-TRAP RGD 3, respectively).
