RETRACTION: Diffusion‐Weighted and Dynamic Contrast‐Enhanced MRI to Assess Radiation Therapy Response for Head and Neck Paragangliomas

Y. Ota, E. Liao, R. Kurokawa, et al., “Diffusion-Weighted and Dynamic Contrast-Enhanced MRI to Assess Radiation Therapy Response for Head and Neck Paragangliomas,” Journal of Neuroimaging 31, no. 5 (2021): 1035-1043, https://doi.org/10.1111/jon.12875. The above article, published online on 18 May 2021 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Rohit Bakshi; American Society of Neuroimaging; and John Wiley & Sons, Inc. The retraction has been agreed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 exclusion criteria described in the article were not followed during the study. Furthermore, the age and sex of three patients were inaccurately described in relation to the figures presented. The authors explained that although one patient technically met the exclusion criteria, the authors included this case based on their interpretation that prior interventions did not affect the intracranial lesions analyzed. They also acknowledged that the age and sex of three patients were inaccurately described. The editors concluded that the explanation provided was insufficient to restore confidence in the results and conclusions of the study. E. Liao, R. Kurokawa, F. Syed, A. Baba, M. Kurokawa, and A. Srinivasan agreed to the retraction. The remaining authors could not be reached for final confirmation.
