Convert Millicuries to Megabecquerels
Convert Millicuries (mCi) to Megabecquerels (MBq) instantly and accurately.
Conversion Formula
MBq = mCi × 37
About Millicuries
The millicurie (mCi) equals 3.7 × 10⁷ Bq = 37 MBq. The primary clinical nuclear medicine unit in the US: ¹⁸F-FDG PET doses are 8-15 mCi; ⁹⁹mTc cardiac stress tests use 25-35 mCi; ¹³¹I hyperthyroidism therapy uses 5-30 mCi. US pharmacopeia and NRC regulations specify doses in mCi. 1 mCi = 3.7 × 10⁷ Bq.
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.
