Mangafodipir (sold under the brand name Teslascan as mangafodipir trisodium) is a contrast agent delivered intravenously to enhance contrast in magnetic resonance imaging (MRI) of the liver. It has two parts, paramagnetic manganese (II) ions and thechelating agent fodipir (dipyridoxyl diphosphate, DPDP). Normal liver tissue absorbs the manganese more than abnormal or cancerous tissue. The manganese shortens the longitudinal relaxation time (T1), making the normal tissue appear brighter in MRIs. This enhanced contrast allows lesions to be more easily identified.
The condensation of pyridoxal 5-phosphate (I) with ethylenediamine (II) in methanol by means of NaOH gives the corresponding diimine (III), which is reduced with hydrogen over Pt/C in methanol/water yielding the expected diamine (IV). The reaction of (IV) with bromoacetic acid (V) by means of NaOH in methanol/water affords the N,N’-diacetic acid derivative (VI), which is finally treated with MnCl2 in water containing NaOH.

Today, while I was at work, my cousin stole my iphone
and tested to see if it can survive a 25 foot drop, just so she can be a internet sensation. My iPad is now
broken and she has 83 views. I know this is entirely off topic but
I had to share it with someone!
