Tumors of the parotid gland: MR imaging characteristics of various histologic types.

Diagnostic value of MR imaging of parotid gland tumors

Diffusion weighted MR imaging of parotid gland tumors

Diffusion-weighted echo-planar MR imaging of primary parotid gland tumors: is a prediction of different histologic subtypes possible?

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. MATERIALS AND METHODS One hundred forty-nine consecutive patients with suspected tumors of the parotid gland were examined with an epiDWI sequence by using a 1.5T unit. Image analysis was performed by 2 radiologists i...

Imaging characteristics of recurrent pleomorphic adenoma of the parotid gland.

BACKGROUND AND PURPOSE Pleomorphic adenoma is the most common parotid neoplasm. It has a relatively high rate of recurrence after surgery. Imaging features of recurrent parotid pleomorphic adenoma have been infrequently reported in the radiology literature. In the present study, we reviewed our institutional experience with imaging of recurrent parotid pleomorphic adenomas. MATERIALS AND METH...

MR imaging of parotid tumors: typical lesion characteristics in MR imaging improve discrimination between benign and malignant disease.

BACKGROUND AND PURPOSE The surgical approach to parotid tumors is different for benign and malignant neoplasms, but the clinical symptoms do not correlate well with histology. Difficulties in tumor classification also arise in imaging modalities, in which sonography has the lowest and MR imaging, the highest accuracy. The purpose of this study was to review our experience using conventional MR ...
