When to use
When reports, orders and console units disagree.
How it works
1 mCi = 37 MBq = 0.037 GBq = 1000 µCi.
Key points
- Unit conversion only — no decay correction.
References
- SI / conventional NM activity units (1 mCi = 37 MBq)

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
