Distinguishing of Pleomorphic Adenomas From Other Types of Parotid Tumors by Diffusion-Weighted MR Imaging

Until now, many articles have been published to declare that apparent diffusion coeficient calculation (ADC) by diffusion-weighted imaging (DWI) is a helpful method for differantiating malignant from benign parotid gland tumors. Habermann et al. in 2005 described that diffusion-weighted echo-planar MRI seems to be a valuable tool for differentiating benign from malignant primary parotid gland tumors in fifty consecutive patients (1). We read with interest the recent article of the same group in the January 2009 issue of the AJNR (2). The authors reached one different conclusion in one hundred thirty-six patients with parotid tumors. They claimed that, DWI has … Continue reading >>
