[Modern neuroradiologic diagnosis and interventional strategies for the ENT physician]

The value of imaging and interventional neuroradiological methods in ENT is surveyed. The role of CT and MRI is discussed in the diagnosis of various diseases. CT remains the method of choice in inflammatory paranasal sinus disease and in craniofacial trauma, whereas MRI has become the preferred imaging technique in patients with sensorineural hearing loss. CT and MRI are complementary in the assessment of skull base tumors. Preoperative embolization facilitates surgery of highly vascular tumors. Endovascular procedures play a prominent role in the control of hemorrhages of the head and neck region and are the method of choice in the treatment of arteriovenous fistulas.
