Issues of radiation dose received by patients via CT have been extensively disputed by radiologists and reported by the media. In recent years there has been considerable research performed to find ways for reducing radiation exposure from CT. Herein, we will discuss specific measures that have ...
Computed Tomography (CT) scans are one of the most frequently-used imaging tools in medicine. In fact, more than 72 million scans are performed each year to diagnose various medical conditions. But public health concerns persist about radiation exposure from these tests—especially when given to c...
"The 80-milligray dose is equivalent to theradiationexposureduring a medical diagnostic imaging procedure such as a CT scan, which is routinely used in conjunction with stem cell therapy," explains Sergey Leonov, director of the Phystech School of Biological and Medical Physics at MIPT, who also...
Glycyrrhizin (GL) is a direct inhibitor of HMGB1 which acts as an alarmin when excreted into the extracellular space. High-dose radiation in radiotherapy induces collateral damage to the normal tissue, which can be mitigated by GL inhibiting HMGB1. The p
Ionizing radiation exposure from medical diagnostic imaging has greatly increased over the last few decades. Approximately 80% of patients who undergo medical imaging are exposed to low-dose ionizing radiation (LDIR). Although there is widespread consensus regarding the harmful effects of high doses of...
it is shown that standard dose CT scan gives significant radiation burden to patients, especially those in need of multiple scans. In this study, we consider low-dose and ultra-low-dose (LDCT and ULDCT) scan protocols that reduce the radiation exposure close to that of a single X-ray, wh...
These concerns include common screening foes, such as false-positive tests, overdiagnosis and the negative psychological impact of screening; others more unique to LDCT LCS, including appropriate risk stratification of potential participants, radiation exposure and incidental findings; and then, crucially ...
It has been well-established that acute radiation exposures increase the risk of leukemia. However, it is still unknown whether these leukemia risk estimates could be extrapolated to occupational populations who receive repeated low-dose radiation exposure. The purpose of this study was to estimate qu...
Along with the promise of CT screening came worries over the effects of radiation exposure on patients, as even the low-dose exam delivers more radiation than an X-ray—radiation that could affect DNA and potentially lead to cancer. Studies of these potential effects that rely on epidemiology,...
All these molecular changes are indicative of long-term premature dysfunction and suggest a mechanistic explanation to the epidemiological data showing increased risk ofcardiovascular diseaseafter low-dose radiation exposure, the authors conclude.
