Sentence examples for radioactivity amount from inspiring English sources

The planar image tended to overestimate the true radioactivity amount (by ~5 % on average) while the SPECT studies tended to underestimate the radioactivity concentration by a similar amount (−4 % on average).

The content of detectable radioactivity in plasma fraction increased from 30%% after 5 min to 50%% after 2 h p.i., while radioactivity amount in the blood cell fraction decreased over time.

Here also multinuclide sources are ideally suited, as they allow for quantification of radioactivity amount of the various nuclides, provided that they are sufficiently long lived (medium half-life radionuclides might also be used, but errors are higher).

The radioactivity amount of [18F]F2 using irradiation with deuterons ranged between 4 and 8 GBq (70-100 MBq. μAh−1) and using proton irradiation, the [18F]F2 production ranged between 25 and 35 GBq (800-1100 MBq. μAh−1).

Specific activity was determined by counting an aliquot of the product in a dose calibrator for radioactivity amount and performing HPLC analysis of the aliquot.

Tailoring peptide receptor radionuclide therapy (PRRT) according to dosimetry has been shown to be of great value in clinical practice and should replace the criteria of administering a fixed of radioactivity amount or an activity correct for the patient body weight or surface [ 20].

Dispensing of radioactivity amounts of 10, 6, 4, and 2 mCi were requested.

The starting radioactivity amounts were 237, 91.6, and 255 mCi, each in a volume of 1 mL.

The aforementioned radioactivity amounts corresponded to volumes greater than 20 μL in order to minimize error due to dispensing of small volumes.
