  • Title: A pitfall in detection of intracranial unruptured aneurysms on three-dimensional phase-contrast MR angiography.
    Author: Araki Y, Kohmura E, Tsukaguchi I.
    Journal: AJNR Am J Neuroradiol; 1994 Oct; 15(9):1618-23. PubMed ID: 7847204.
    Abstract:
    We report three cases of intracranial unruptured aneurysm evaluated with MR angiography using both three-dimensional time-of-flight and three-dimensional phase-contrast techniques. It has been said that the phase-contrast technique has advantages over the time-of-flight technique in the detection of intracranial aneurysms. However, in our three cases, three-dimensional time-of-flight MR angiography clearly showed the intracranial unruptured aneurysms, but three-dimensional phase-contrast MR angiography failed to show them.
