Follow up of coiled intracranial aneurysms 111 Conclusion The aim of the present study was to evaluate the diagnostic performance of CEMRA in the follow-up of cerebral aneurysms treated by endovascular coiling. The results are not better than those reported in studies employing TOF-MRA, but they do support the conclusion drawn by Schaafsma et al. that MRA can be used for the follow-up of coiled aneurysms.19 The high NPV warrants a confident exclusion of recanalization with MRA. But, as a consequence of the low PPV, additional DSA may be necessary in case of incomplete occlusion seen on CEMRA, to assess whether repeat treatment is necessary.
