Abstract:
The results of palpation, CT and MRI and high resolution ultrasound were compared in 100 patients with malignancy of the head and neck. Ultrasound detected far more lymph nodes than the other methods. These diagnostic findings were compared with the operative and histological results in 62 patients. Ultrasound proved superior to the other methods: a lymph node metastasis was missed in only 2 patients by sonography, whereas in 20 patients metastases were overlooked by CT and MRI scans, and in 27 patients by palpation. High resolution ultrasound is at present the most reliable method for the detection of lymph nodes in the head and neck.
