Dynamic Contrast Magnetic Resonance Imaging ( XXXX -MRI) and Diffusion Weighted MR Imaging (DWI) for Differentiation between Benign and Malignant Salivary Gland Tumors.

BACKGROUND: @entity5 form nearly 3% of @entity135 . Due to their large histological variety and @entity2103 , pre-operative diagnosis and differentiation of benign and malignant @entity5 are a major challenge for radiologists. OBJECTIVE: The majority of these @entity5 are benign; however, sometimes they tend to transform into a malignant form. Functional MRI techniques, namely dynamic contrast enhanced ( @entity9243 -) MRI and diffusion-weighted MRI (DWI) can indicate the characteristics of @entity5 tissue. METHODS: @entity9243 -MRI analysis is based on the parameters of time intensity curve (TIC) before and after contrast agent injection. This method has the potential to identify the angiogenesis of @entity5 . DWI analysis is performed according to diffusion of water molecules in a tissue for determination of the cellularity of @entity5 . CONCLUSION: According to the literature, these methods cannot be used individually to differentiate benign from @entity5 . An effective approach could be to combine the aforementioned methods to increase the accuracy of discrimination between different @entity5 types. The main objective of this study is to explore the application of @entity9243 -MRI and DWI for assessment of @entity5 types.
