IMRT may obtain a better dose distribution and a reduction of dose inhomogeneities, but it is more time consuming as concerns planning and delivery and it is, of course, more expensive.
It is unquestionable that carbon ion therapy shows a better dose distribution than SBRT in terms of the low-dose irradiated volume of the lung [ 27], but less is known about comparing carbon ion therapy with proton therapy.
These units allow a better understanding of dose and will facilitate the future cross-comparison of biological data.
It leads to a better knowledge of dose distribution to the target and critical organs and allows more individualized and conformal treatment.
For some metals, there is some evidence that loading is a better indication of dose than is concentration; in studies of children's exposure to lead, the surface loading of lead on carpet was more strongly correlated with blood lead levels than was the concentration of lead in the dust [ 15, 16].
Oh, if only scientists were allowed to include an "Ants, Better With Dose of Humanity (and Humor)" (Side Effects, April 25) in their scientific articles.
With conformal radiotherapy techniques, acute and late toxicities can be reduced because of better dose conformity and reduced doses to normal tissue.
To acquire a better understanding of dosing, implant mechanism of action, and how certain cell types affect remodeling of central nervous system (CNS) tissue, a refillable cell encapsulation device was developed for introducing cells into the brain while keeping them physically isolated from contact with brain tissue with a semipermeable membrane.
Future implementation of combination therapy comprising HDACi and radiotherapy with require a better understanding of dosing schedules, and there is still insufficient consensus regarding therapy response evaluation.
Because the BED incorporates factors related to delivery of treatment and tissue factors, it is a better representation of the dose delivered to a given tissue than conventional dose [ 6- 8].
