| Core Tip |
After recent groundbreaking stroke clinical trials have shown positive outcomes with endovascular therapy, the use of imaging, particularly magnetic resonance imaging (MRI) is expected to increase in this setting. Iodinated contrast material (ICM) is inherent to this scenario and can be deposited in the brain after intra-arterial or intra-venous injection. Differentiation of ICM from hemorrhagic changes is of upmost clinical importance. This paper demonstrates the signal chara-cteristics of in vitro ICM with routine MR sequences [including not previously reported changes on gradient-echo (GRE)]. Changes at high magnetic field (3T) are to the best of our knowledge described for the first time, with T2 hypo intensity as the signal change with greatest conspicuity as compared with other routine brain sequences. Furthermore, no significant conspicuity/hypo intensity on GRE is demonstrate and postulated as a way to differentiate contrast deposition (T2 hypo intensity or T1 hyper intensity) from hemo-rrhagic changes. |
