Tests and Radiation Amounts
FLAT FILMS (mrad)
Low-dose
- Head <1
- C-spine <1
- Thracic spine <1
- CXR <1
- Extrem <1
High-dose
- L-spine <1250
- Pelvis <350
- Hip <450
- IVP <900
- Urethrocyst <1500
- KUB <500
CT (1cm slices)
- Head <50
- Chest <1000
- Upper abd <3000
- Lower abd <9000
ANGIO
- Cerebral <100
- Cardiac cath <500
Aortography <100
V/Q scan <215
(class C injectable technetium, xenon even safer)
Pregnancy
Greatest risk during organogenesis (8-12wk)
IV contrast not teratogenic (class B)
PO contrast not absorbed
EXPOSURE RISK (mrads)
<5,000 = safe
~10,000 = small risk childhood CA
~15,000^ = 6% chance mental retard
<3% chance childhood CA
^Considered max
Always use sheild when possible
