New endobronchial ultrasound imaging for differentiating metastatic site within a mediastinal lymph node

Abstract

A newly developed endobronchial ultrasound processor system (EU-ME1; Olympus Ltd., Tokyo, Japan) improves the quality of ultrasound image by elevating cycles per minute. We report identification of mediastinal lymph node metastasis in a patient with small cell lung cancer. The new endobronchial ultrasound system images enabled visualization of metastatic site within the subcarinal lymph node by the combination of ultrasound image and Doppler mode.
