Magnetic resonance imaging (MRI) before thrombectomy was routinely performed in all patients without selection biases unless contraindicated. Patients also typically underwent follow-up magnetic resonance (MR) within 48 h after thrombectomy. The multimodal MRI protocol included diffusion-weighted imaging, perfusion-weighted imaging, T2∗ gradient-recall echo (GRE), and fluid-attenuated inversion recovery (FLAIR) sequences. We included patients who had serial T2∗ GRE before and 48 h after thrombectomy. The local institutional review board of University of California at Los Angeles approved the study. Informed consent was obtained from the patient or their representative.
Merci retriever
The Merci Retriever is a medical device designed for the removal of blood clots from the brain during ischemic stroke procedures. It functions as a catheter-based system that can be used to capture and extract clots from occluded blood vessels.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
