Sentence examples for radioactivity dose from inspiring English sources

The personal radioactivity dose during the subsequent 68Ga radiolabelling procedure observed was 1 μSv.

Values were corrected for decay and the percentage of the total injected radioactivity dose (%ID g−1) for every tissue was calculated as percentage of the total injected radioactivity dose divided by the weight of the tissue.

Radioactivity concentration was normalized with injected radioactivity dose (ID) and body weight, expressed as%ID/cm3 × kg.

This, in addition to higher injected radioactivity dose per gram, might in part explain higher plasma values of female rats.

The ex vivo biodistribution results were expressed as percentage of injected radioactivity dose per gram of tissue (%ID/g).

Therefore, the fairly large injected radioactivity dose for imaging needs to decay considerably to reach the measurement window of a γ-counter.

This would allow the use of short living radioisotopes in PET imaging of slow accumulating markers and leads to enhanced signal-to-noise ratios and lower radioactivity doses.

Using [18F]BF4 − at specific activities in the range previously reported, initial in vivo extracellular BF4 − concentration may well exceed this level after administration of radioactivity doses sufficient for high-quality PET imaging in mice.

Further details including tissue-specific calculations are described in the Additional file 1. Radiolabelling quality control (QC) included (1) ITLC and HPLC of the product to confirm sufficient radiochemical purity (>95%), and (2) measurement of the radioactivity concentration for the preparation of individual radioactivity doses (target≈100 MBq) at a volume dose of ≈0.2 mL.

In addition for in vivo imaging studies, higher radioactivity doses needed to be injected in order to have a sufficient signal with multi-pinhole SPECT, which has an intrinsic low sensitivity, and this translated into the need of higher doses of tilmanocept.

As a result higher radioactivity doses can be administered without risk of nephrotoxicity.
