'''Medronic acid''' ([conjugate base](/source/conjugate_acid), '''medronate'''), also known as '''methylene diphosphonate''', is the smallest [bisphosphonate](/source/bisphosphonate). Its [complex](/source/complex_(chemistry)) with radioactive [technetium](/source/technetium), [<sup>99m</sup>Tc medronic acid](/source/technetium_(99mTc)_medronic_acid), is used in [nuclear medicine](/source/nuclear_medicine) to detect bone abnormalities, including [metastases](/source/Metastasis).
