Radiation Doses for Common CT Scans. Common types of CT scans and the amount of radiation you would absorb from them include: Belly and pelvis: 10 mSv, equal to about 3 years of background...
Radiation Dose to Adults From Common Imaging Examinations. For the most current information, visit radiologyinfo.org. 05.22. Note: This chart simplifies a highly complex topic for patients’ informational use. The effective doses are typical values for an average-sized adult.
Here are some approximate comparisons of background radiation and effective radiation dose in adults for several radiology procedures described on this website. These values can vary greatly, depending on the size of the patient and the type of imaging technology being used.
Effective dose is a radiation unit that depicts the uniform whole-body dose that has the average same nominal risk of carcinogenesis as any given nonuniform exposure (such as a CT scan restricted to one body part). The units are millisieverts.
How much radiation is delivered in tests like CT scans and x-rays? The graph below shows the range of radiation exposure a patient may receive from different medical exams. The dotted line indicates the most likely dose.
This document contains radiation dosimetry information from CT scans and can be used by investigators to estimate the dosimetry information required by the JRSC or RDRC for research protocols involving human subjects.
The radiation dose sheet (hereafter referred to as dose sheet) is a form generated by the CT scanner that displays important information about a CT examination. This sheet is also referred to as a dose sum-mary page or patient protocol page in different literature and clinical settings.
