Abstract:
Our aim was to review the clinical applications of diffusion-weighted magnetic resonance imaging in the head and neck. Diffusion-weighted magnetic resonance imaging plays a role in the differentiation of benign from malignant head and neck tumors, squamous cell carcinoma from lymphoma, and metastatic from benign lymphadenopathy as well as in the selection of the biopsy site. It can be used for the differentiation of recurrent tumors from posttreatment changes and in monitoring the patient after radiotherapy. It helps in the differentiation of necrotic tumors from abscesses. Additionally, it can be used for the diagnosis and grading of diffuse autoimmune diseases, such as Sjogren and Graves diseases.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
