RETRACTION: Intracranial Paragangliomas Versus Schwannomas: Role of Dynamic Susceptibility Contrast Perfusion and Diffusion MRI

Y. Ota, E. Liao, A. A. Capizzano, et al., “Intracranial Paragangliomas Versus Schwannomas: Role of Dynamic Susceptibility Contrast Perfusion and Diffusion MRI,” Journal of Neuroimaging 32, no. 5 (2022): 875-883, https://doi.org/10.1111/jon.13002. The above article, published online on 12 May 2022 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Rohit Bakshi; American Society of Neuroimaging; and John Wiley & Sons, Inc. The retraction has been agreed upon following an investigation conducted by the University of Michigan. The investigation determined that the patient inclusion and exclusion criteria described in the article were not followed during the study. Duplication and reuse of data from three individual patients were also identified. The authors stated that the study variables were unaffected by the conditions outlined in the exclusion criteria. However, as the first author left the institute and was unresponsive, the co-authors and the journal could not obtain original data for further investigation or verification of the results. As a result, the editors consider the study's results and conclusions unreliable. The authors, E. Liao, A. A. Capizzano, A. Baba, R. Kurokawa, M. Kurokawa, and A. Srinivasan agree to the retraction. Acknowledgement of the retraction could not be obtained from Y. Ota.
