Color Doppler and Mri Diffusion in Major Salivary Gland Masses

Combined Role of Color Doppler and Diffusion Weighted MRI In Differentiation Between Benign and Malignant Tumors of Major Salivary Glands

This study intend to evaluate the combined value of ADC and COLOR DOPPLER in differentiating benign and malignant salivary gland tumors in comparison to histopathological findings and its use in preoperative prediction of benign and malignant masses.

the study aim to achieve preoperative differentiation between benign and malignant masses of the major salivary glands using the ADC values and Color Doppler values (PSV - PI - RI)

Inclusion Criteria:

1- patients must be 18 of age or older. 2= patients must have a suspicious swelling in major salivary glands.

Exclusion Criteria:

1. Patients with history of metal plates or screws or artificial joints.
2. Patients who have phobia of indoor places.
3. Patients with contraindication to MRI like intra-cerebral aneurysmal clips, cardiac pacemaker, and metallic foreign body at region of examination.
