radiation exposurePET/CTautomatic infusion systemSpecially when handling higher energy radioactive sources, such as F-18, the principle that radiation exposure is to be kept as low as possible must be considered. In the first two months of operation of our PET/CT scanner we were performing ...
Over the 7-year study period, 24,393 patients received 34,671 CT scans. The vast majority of patients (17,909) received a single CT. Twenty-six (0.1聽%) patients received more than ten CTs totaling 374 scans with an average radiation exposure of 83.4聽mSv. The maximum lifetime ...

There are no known health risks associated with having an MRI scan.How much?A CT scan A CT scan produces around 7 mSv, or around the same amount of radiation as you'd expect to absorb if you spent a year in Cornwall, where the sun exposure and radioactive rocks pump up the levels ...
also expose patients to ionizing radiation, CT has appropriately received the greatest scrutiny because of the relatively high radiation dose per exam – although it comprises about 15% of all medical imaging procedures, it produces approximately half of the population's medical radiation exposure [4...
CT scanning: A major source of radiation exposure CT scanning is a relatively high dose procedure that is becoming much more common worldwide. In the mid-1990s, CT scanning accounted for about 4% of proced... PW Wiest,JA Locken,PH Heintz,... - 《Seminars in Ultrasound Ct & Mr》 被引...
with CT. Referring emergency physicians were also largely unaware that there were any potential harmful effects from the radiation exposure, with only 9% aware of the increased cancer risk. Of even greater concern is the fact that the majority of the radiologists performing the CT examinations ...

Full size image Analysis of radiation exposure The exposure dose measured using the NanoDot OSL dosimeters was analyzed with a commercial dosimeter reading device (MicroStar, Landauer)....
To compare radiation exposure associated with daily practice cardiovascular (CV) examinations performed on two different multidetector computed tomography (MDCT) scanners, a conventional 64-MDCT and a third-generation dual-source (DS) MDCT.In this retrospective study, 1458 patients who underwent CV ...
