For diagnosing head and neck ailments, tests that use radiation are always less desirable than those that don't. Otolaryngologists have a wide range of techniques available to them, including CT or "CAT" scans, MRI and ultrasound. CT uses significant radiation and MRI a lower amount, but ultrasound is a non-invasive, non-radiating technique. It does not require injection of radioactive contrast material and has no side effects.
