A standardized extended field‐of‐view sonographic examination technique of the neck is evaluated. In a prospective study we screened 50 patients suspected of having carcinoma or lymphoma for enlarged cervical lymph nodes. After conventional CT of the neck, extended field‐of‐view sonography was performed using defined axial parallel scanning sequences. The results were interpreted separately by two radiologists. Of 245 lymph nodes (diameter 1 cm or greater) diagnosed with conventional CT, 218 were correctly identified by extended field‐of‐view ultrasonography. With respect to the entire neck, the sensitivity of extended field‐of‐view sonography was 92%, and the correlation coefficient between the methods was r = 0.98 (P < 0.001). Fifteen of 17 false‐negative lymph nodes were located in the mandibular angle region. False‐positive results (N = 10) were caused by misinterpretation of primary tumors, blood vessels, lobulated salivary glands, and double imaged lymph nodes. Our results indicate that extended field‐of‐view sonography in parallel scanning sequences represents a reliable method for the detection of cervical lymphadenopathy.
