Abstract Thyroid nodules are very common clinical and radiological entities, their incidence increases with age and they have a variable appearance from the solid to the cystic nature, however, most of the nodules tend to have a benign nature and the malignancy has been reported in less than 5% of the nodules (Shokry et al., 2018). Despite great improvement in diagnostic techniques there is still a large problem to use a non-invasive and reliable technique to differentiate benign from malignant thyroid nodules. To date, little information is available about the use of MR imaging in the diagnosis of thyroid cancer (Messina et al., 2020). Diffusion-weighted (DW) magnetic resonance imaging (MRI) is a type of functional imaging that was employed at first for neuro-imaging purposes, recently it had gained a wide range of extra cranial applications in different body parts including the head and neck regions for differentiation of benign and malignant nodules, helping in the tumor staging, and for detection of the post operative recurrences and the residual tumor masses(Shokry et al., 2018). Moreover, it had been described as a follow up study for assessment of the therapeutic responses in the head and neck |
