Diffusion-Weighted Echo-Planar MR Imaging of Primary Parotid Gland Tumors: Is a Prediction of Different Histologic Subtypes Possible?

Abstract

BACKGROUND AND PURPOSE: Our aim was to determine the value of echo-planar diffusion-weighted MR imaging (epiDWI) in differentiating various types of primary parotid gland tumors.

Head and Neck Tumors: Assessment of Perfusion-Related Parameters and Diffusion Coefficients Based on the Intravoxel Incoherent Motion Model

“…8,9 However, this concept has not yet been established. 10 Perfusion is a very important marker of many physiologic or pathologic processes. For example, the perfusion parameter can be used as a biomarker for predicting the responsiveness of some types of tumors to chemotherapy.…”

Apparent Diffusion Coefficient Mapping for Sinonasal Diseases: Differentiation of Benign and Malignant Lesions

“…2 Diffusion-weighted imaging has been used in the diagnosis of extracranial lesions; for example, recent studies showed that ADC measurement was useful in the differentiation of benign and malignant lesions of the lymph nodes and salivary glands. [3][4][5][6] Low ADCs indicate limited diffusion of water molecules in the tissue. Theoretically, therefore, a tumor or area within a tumor with low ADC contains a greater number of cells than one with high ADC.…”
