Modern CT scanners provide automatic dose adjustment systems, which are promising options for reducing radiation dose in pediatric CT scans. Their impact on patient dose, however, has not been investi...
Size-specific dose estimates (SSDEs) are the latest focus of interest among medical physicists studying radiation dose to the patient in computed tomography (CT). This study aims to make conversions f...
Many patients at our pediatric hospital have had a contrast-enhanced CT of the abdomen and pelvis performed by an outside imaging facility before admission. We have noticed that many of these exams ar...
Given the rising utilization of medical imaging and the risks of radiation, there is increased interest in reducing radiation exposure. The objective of this study was to evaluate, as a proof of princ...
The extensive literature review on human epidemiological studies suggests that low dose ionizing radiation (LDIR) (≤100 mSv) or low dose rate ionizing radiation (LDRIR) (
Radiation dose reduction has been a primary driver of technology development in multi-detector computed tomography (MDCT). The optimization of radiation dose for patient and task specific ...
Lung cancer screening programs are still discussed in Europe today, and one of the concern is radiation due to iterative CT. The aim of this monocentric, prospective, non randomized study ...
The noncontrast-enhanced chest computed tomography (CT) is an emerging diagnostical tool in patient with chronic obstructive pulmonary disease (COPD). As shown in previous studies and poin...
The purpose of this study is to assess new low radiation dose techniques for clinical PET/CT scans through intra-individual comparison between a clinical, standard dose scan and a low-dose...
Current treatments for limited stage small cell lung cancer have poor cure rates. The addition of chest radiation to chemotherapy improves cure rates, but these cancers still come back in...
The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.
Administration of the total dose of radiation (RADIATION DOSAGE) in parts, at timed intervals.
A treatment schedule in which the total dose of radiation is divided into large doses.
The relationship between the dose of administered radiation and the response of the organism or tissue to the radiation.
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).
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
