What is Sonographic Anatomy of the Cervical Esophagus about?

## Abstract ## Purpose Although conventional sonography is used widely for evaluation of the gastroesophageal junction, its use in the cervical esophagus is still limited. The aim of this study was to assess the use of sonography to demonstrate this portion of the esophagus. ## Methods The cervical esophagi in 60 cadavers and 435 healthy volunteers were examined sonographically. Among the healthy subjects 182 were scanned with a transducer operating at 7.5 MHz, 183 with a 10.0‐MHz transducer, and 70 with a 12.0‐MHz transducer. Sonographic layer patterns were compared among the groups. Sonographic and histologic analyses were also performed on 3 cadaveric esophageal specimens to correlate the sonographic appearances with the anatomical findings. ## Results Scans of the cadavers showed that the cervical esophagus lay between the trachea and vertebrae, with its origin at the midline; it gradually moved to the left as it descended toward the trunk. It moved to the right when the cadaver's head was turned to the left and the trachea was pushed gently to the left. Based on these anatomical characteristics, visualization of the cervical esophagus was optimized by scanning from both the le
