Timing adjustment in gadolinium MR angiography by raw data recombination. Technical note.

To solve the problem of injection timing in gadolinium MR angiography, a simple procedure is proposed which allows the acquisition interval to be chosen after injection. Starting simultaneously with the injection, several consecutive acquisitions are made, after which raw data acquired in a contiguous interval with a variable starting time are recombined to one data set, which is then used for delayed image reconstruction.
