Contrast-enhanced ultrasonic diagnosis of head and neck tumor

Phase 1

• Conditions: Head and neck tumor

• Registration Number: JPRN-jRCTs021180035
• Lead Sponsor: Shiga Kiyoto

Brief Summary

This study aimed to confirm the usefulness of contrast-enhanced ultrasonography to diagnose the head and neck tumors. It seemed that the differential diagnoses were possible in salivary gland tumors. We found that differential diagnosis between pleomorphic adenoma and Warthin tumor was possible to analyze the time intensity curve of these tumors.
