Abstract: A process for producing 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) including salts and hydrates thereof of general formula (I) from the respective cyclen. The process involves the use of cationic- and anionic exchange resins and solvent treatments to remove the organic and inorganic contaminants. Any cations present in the raw DOTA or other contaminants resulting from the reaction of cyclen are largely reduced in early stages of the process allowing to obtain good yields of DOTA in a purified grade and in an easier and reliable way. The process is useful for the production of DOTA, of macrocyclic compounds including metal ions complexes thereof and of compositions including the macrocyclic compounds that can be used as contrast agents for magnetic resonance imaging.

Abstract: For each of a number of landmarks in an image an initial position of the landmark is defined. Next a neighborhood around the initial position comprising a number of candidate locations of the landmark, is sampled and a cost is associated with each of the candidate locations. A cost function expressing a weighted sum of overall gray level cost and overall shape cost for all candidate locations is optimized. A segmented anatomic entity is defined as a path through a selected combination of candidate locations for which combination the cost function is optimized. During optimization towards the optimal segmented surface/volume graph traversal methods are exploited.
