Quite rare to jump straight to an MRI - a chest MRI is a half hour deal. More common to do a CT Chest which has a 1:500 risk of causing cancer

- maneesh 7y agoDoes this mean that out of the 5000 false positives, 10 people will actually GET cancer by doing a follow-up CT exam?
- pmiller2 7y agoWe don't really know. Data that show X dose of radiation increases the probability of developing cancer by Y% is based on studies on survivors of atomic blasts. The number of people exposed to an amount of radiation equivalent to a handful of CT scans is pretty small relative to the effect size that's claimed, so there is reason to be skeptical. See https://www.scientificamerican.com/article/how-much-ct-scans-increase-risk-cancer/ https://www.scientificamerican.com/article/how-much-ct-scans... for a jumping off point into this type of research.
