The exact structure of the complex is not known.[2][3] Manufacture99mTc-MDP must be prepared in a radiopharmacy. It is usually supplied as a "cold kit" to which radioactive 99mTc from a generator is added. Kit composition may vary between suppliers, but contents typically includes medronic acid, stannous chloride dihydrate and sometimes ascorbic acid.[4] Pertechnetate, eluted from the generator is added to the kit vial, which is swirled and left to stand. The labelling efficiency, an indication of how much 99mTc remains in pertechnetate form rather than bound to the MDP, can be measured using chromatography.[5][6][7][8]References1. ^{{cite journal| pmid=15788608 | doi=10.2214/ajr.184.4.01841266 | volume=184 | issue=4 | title=Comparison of FDG PET and SPECT for detection of bone metastases in breast cancer | year=2005 | journal=AJR Am J Roentgenol | pages=1266–73 | last1 = Uematsu | first1 = T | last2 = Yuen | first2 = S | last3 = Yukisawa | first3 = S | last4 = Aramaki | first4 = T | last5 = Morimoto | first5 = N | last6 = Endo | first6 = M | last7 = Furukawa | first7 = H | last8 = Uchida | first8 = Y | last9 = Watanabe | first9 = J}} {{Radiopharmaceuticals}}{{pharma-stub}}2. ^1 FDA Label: MDP Multidose Utilipack 3. ^KEGG Drug: D02029 4. ^{{cite web|title=List of labelling kits for the preparation of a technetium-99m labelled bone scanning agent|url=https://humanhealth.iaea.org/HHW/Radiopharmacy/VirRad/Selection_of_Labelling_Kit/List_of_labelling_kits/index.html|website=Human Health Campus|publisher=IAEA|accessdate=3 March 2017}} 5. ^{{cite web|title=MDP Bracco|url=http://www.nuclearonline.org/PI/BRACCO%20MDP%20doc.pdf|publisher=Bracco Diagnostics|accessdate=3 March 2017}} 6. ^{{cite web|title=Kit for the Preparation of Technetium Tc 99m Medronate for Injection|url=http://www.pharmalucence.com/images/MedronateInsert.pdf|publisher=Pharmalucence|accessdate=3 March 2017}} 7. ^{{cite web|title=TechneScan MDP Kit for the Preparation of Technetium Tc 99m Medronate Package Insert|url=http://www.nuclearonline.org/PI/Mallicknrodt%20MDP.pdf|publisher=Mallinckrodt Medical|accessdate=3 March 2017}} 8. ^{{cite journal|last1=Mather|first1=SJ|last2=Ellison|first2=D|title=Reduction-mediated technetium-99m labeling of monoclonal antibodies.|journal=Journal of Nuclear Medicine|date=May 1990|volume=31|issue=5|pages=692–7|pmid=2341907|url=http://jnm.snmjournals.org/content/31/5/692.long}} 2 : Bisphosphonates|Technetium-99m |
