[B-mode sonography of the neck. Comparison of results of sonography, computer tomography and pathomorphology].

High-resolution B-scan sonography has so far been hardly utilized in the investigation of neck tumours. The results of B-scan sonography, computed tomography, and anatomic pathology are compared and discussed. Lymph node tumours of the neck are easily and precisely recognized by ultrasonography. The rate of false positive tumours diagnoses is higher in B-scan sonography than by computed tomography. The rate of false negative diagnoses is the same with both methods. The technical development of B-scan sonography will widen its application in E.N.T. surgery.
