All that follows is from the show notes of EM Cases 49.
The downstream risks of CT radiation are under-appreciated in practice
- Up to 2% of all cancers in the United States are estimated to be iatrogenic and caused by radiation associated with use of CT scans, and the use of CT scans has risen considerably over the last 3 decades
- https://www.xrayrisk.com/ is a useful tool that can provide individualized cancer risk statistics for patients by age, gender and type of CT scan, and can aid in shared decision making
- Clinicians should weigh the risk-benefit ratio of clinical imaging and weigh factors such as age, presentation, and patient preferences when ordering medical imaging
