radiation doseBACKGROUND: 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 principle, CT scans performed at radiation doses equivalent to that of a ...
The estimated size of chest lymph nodes and lung nodules seen on CT images varies significantly when the same nodes or nodules are examined using lower versus higher doses of radiation, a new study shows. The size of lymph nodes and lung nodules is an important determinant of treatment and t...
PURPOSE: To estimate patient-specific radiation dose and cancer risk for pediatric chest computed tomography (CT) and to evaluate factors affecting dose and risk, including patient size, patient age, and scanning parameters. MATERIALS AND METHODS: The institutional review board approved this study and...

dose chest CT that results in a radiation dose reduction of 42% when compared with traditional dose chest CT exams. In an era of heightened awareness ofradiation exposureto patients frommedical imaging, this is a significant finding," said Sonali Mehandru, MD, one of the authors of the ...
目的:探讨锐影技术在胸部CT增强扫描中的应用价值。方法:随机选取怀疑胸部病变需行CT增强扫描的患者160例,设置质量参考毫安为110mA,将患者随机分为两组并设置扫描方案,实验组:80例采用120kV扫描,使用锐影技术;对照组:80例采用120kV扫描,不使用锐影技术。测量和计算肺尖层面右
7,9 Given the young patient population affected by GTN, and the frequent desire for further pregnancies, avoiding overtreatment is essential, as is the need to minimise the radiation dose. Despite technological advancements, CT chest delivers 7 millisieverts (mSv) of radiation, equivalent to ~...
CT is the major source of radiation exposure to the general population from medical imaging, which is evident from the fact that while CT represents only ~6.3% of all diagnostic radiologic procedures, it contributes to ~43.2% of the collective radiation dose given to the patients [8]. This ...
Adjusting the radiation dose based upon a child's weight can significantly lower the radiation dose associated with pediatric chest computed tomography (CT) scans, according to a study published in the May issue of the American Journal of Roentgenology .
