Sentence examples for brain dose from inspiring English sources

The whole brain dose was 32.25 Gy (15 fractions), and SIB doses to brain metastases were 63 Gy (2 and 3 cm) or 70.8 Gy (1 cm).

When using 2D-CRT, the entire brain dose, which was easier to determine and indirectly related to the maximum irradiation dose, seemed to correlate with the occurrence of radiation-induced brain injury [ 4].

A similar calculation considering only brain cancers after a brain CT suggests a collective organ dose to the brain of 19 800 Gy from an average brain dose of 40 mGy per brain scan.

Because several plausible disease mechanisms centre around systemic effects after whole body irradiation, we used colon doses as an approximation to whole body doses for all analyses, although analyses using brain dose for stroke and lung dose for heart disease produced very similar results (data not shown).

This implies that the lifetime estimated organ dose for a busy interventional cardiologist after 25 years of work in the catheterization laboratory is in the order of magnitude of 1 to 3 Sv as scatter dose measured at the head with a dosimeter and the brain dose that could approximately be a 20 25% of the "external dose".

However, postoperative Gd contrast enhancement differs significantly in individuals because the enhancement depends on the imaging modality, timing, dose of the contrast medium, type of surgery, degree of injury in surrounding brain, dose of steroid, and whether intraoperative parenchymal hemorrhage has occurred.

In particular, children with PF for hematopoietic tumours received a first examination at younger ages than children with no PF, and those predisposed to CNS tumours received higher cumulative brain doses.

The proportion of highly exposed children was also larger in the presence of PF; 12.0% of the patients predisposed to CNS cancer received cumulative brain doses >95th percentile (68.0 mGy).

Children at risk of CNS cancer received a first examination at almost the same ages as children without PF (3.2 years vs 3.4 in average) but received more scans (1.8 vs 1.4 in average) and higher cumulative brain doses (33 mGy vs 23 mGy in average) (Table 2).

The whole-brain dose was substantially decreased with proton therapy.

For the two risk structures (Optical nerve/chiasm and brain stem), dose constraints of 12 Gy (Optical nerve) and 12.5 Gy (brain stem) are commonly accepted in LINAC-based EBRT according to the QUANTEC (Quantitative Analyses of Normal Tissue Effects in the Clinic) recommendations [ 26].
