Question: Regarding the carcinogenic potential of common medical exposures, the equivalent background exposure is:
- Chest XRAY: 5 days
- Skull XRAY: 11 days
- CT Chest and abdomen: 6 years
- Abdominal XRAY: 1 year
- Fluoroscopic procedures carry minimal risk of exposure
Answers:
- false
- true
- false
- false
- false
Explanation:
- Chest X-ray: 3 days, with a lifetime risk of cancer 1 in 1 000 000
- Skull X-ray: 11 days, with a lifetime risk of cancer 1 in 300 000
- Abdominal X-ray: 4 months, with a lifetime risk of cancer 1 in 30 000
- CT chest and abdomen: 4 yr, with a lifetime risk of cancer 1 in 2000–1 in 2500
- There is perhaps a misconception that fluoroscopy represents a relatively innocuous exposure. Interventions like facet joint injections, caudal, and lumbar epidurals requires exposure of between 0.5 – 4 times the dose during an abdominal CT (lifetime cancer risk of 1 in 2000).
