Retraction Note to: Ultrasound Elastography supplement assessing nodal status of magnetic resonance imaging staged cervical N0 patients with nasopharyngeal carcinoma

The original article was published in Cancer Imaging 2019 19:12

Retraction Note to: Cancer Imaging

https://doi.org/10.1186/s40644-019-0199-3

The Editors have retracted this article [1] because figure 2 has been substantially duplicated from a previously published article by Chen B et al., 2018 [2]. There is also significant and uncited overlap in the patient population between the two articles resulting in concerns relating to the scientific validity and novelty of the data.

None of the authors agree to this retraction.
