E-111 Analysis of intracerebral hemorrhage in n established mouse model
BackgroundKontos’ elucidated the theory that iron-mediated free radical production and subsequent oxidative damage was responsible for on-going cerebral degeneration within the infarct following ischemic stroke. The production of free radicals is likely tied to the generation of superoxide following reperfusion of the ischemic brain. Free radical production happens relatively soon after reperfusion but the time to oxidative damage of surrounding tissue is still unknown. It is well-established that ischemic stroke results in loss of autoregulation to cerebral tissues. Ischemic strokes have the potential to transform i...

E-205 In vitro evaluation of full-length, mr-safe interventional passive catheter markers at 3T
ConclusionAlthough worst-case artifacts were observed at 90°, they remained acceptable for use in guide catheters. Additionally, 20-mm marker separation could provide distinct artifacts down the length of a catheter during MRI-guided interventions, despite anatomic tortuosity. The phantom used in this study was shallow, which limited the ability to distinguish between real artifacts and those arising from the solution-air interface. Hence, accuracy of the degree of increased artifact may warrant further investigation. This study simulated worst-case orientations in vitro; more data should be collected in vivo using rea...

P-017 Evaluation of radiofrequency-induced heating in an X-ray and MR-visible interventional catheter at 3.0 T
ConclusionsInitial immersion tests suggest that the worst-case scenario for RF-induced heating of our guide catheter prototype occurs at 95 cm. During the period of our tests, our prototype remained safely under the maximum permitted temperature rise of +2°C/hr of exposure. This study suggests that our guide catheter may be retained during an intra-procedural MRI without the safety risk of RF-induced device heating over time to the patient.Disclosures B. Kilbride: None.
