About Megabecquerels

The megabecquerel (MBq) equals 10⁶ Bq and is the standard clinical nuclear medicine unit outside the US. ⁹⁹mTc bone scans use 740 MBq; ¹⁸F-FDG PET scans use 370 MBq; ¹³¹I diagnostic thyroid scans use 185-370 MBq. European and Australian protocols specify all doses in MBq. 1 MBq = 10⁶ Bq.

About Microcuries

The microcurie (µCi) equals 3.7 × 10⁴ Bq = 37 kBq. Sealed sources for educational and bench-top laboratory use are licensed up to 1-10 µCi under US NRC 10 CFR 30.18; small-animal PET imaging doses of ¹⁸F in preclinical research are expressed in µCi. 1 µCi = 3.7 × 10⁴ Bq.
