Radiation Dose-Dependent Hippocampal Atrophy Detected With Longitudinal Volumetric Magnetic Resonance Imaging.

07:00 EST 1st February 2017 | BioPortfolio

Summary of "Radiation Dose-Dependent Hippocampal Atrophy Detected With Longitudinal Volumetric Magnetic Resonance Imaging."

After radiation therapy (RT) to the brain, patients often experience memory impairment, which may be partially mediated by damage to the hippocampus. Hippocampal sparing in RT planning is the subject of recent and ongoing clinical trials. Calculating appropriate hippocampal dose constraints would be improved by efficient in vivo measurements of hippocampal damage. In this study we sought to determine whether brain RT was associated with dose-dependent hippocampal atrophy.

Medical and Biotech [MESH] Definitions

Administration of the total dose of radiation (RADIATION DOSAGE) in parts, at timed intervals.

The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.

The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).

The relationship between the dose of administered radiation and the response of the organism or tissue to the radiation.

A treatment schedule in which the total dose of radiation is divided into large doses.
