A 20 MHz ultrasound transducer housed in a 6.2 Fr catheter was used to image human esophageal autopsy specimens from six cadavers. Histologic sections taken from the areas imaged were correlated with cross‐sectional sonographic images. Six echo layers were seen in the non‐fluid‐filled esophagus whereas seven echo layers were seen in the fluid‐filled esophagus. These seven layers correspond to the following histologic structures: first hyperechoic layer‐‐mucosa (including squamous epithelium and lamina propria); second thin hypoechoic layer‐‐muscularis mucosae; third very bright hyperechoic layer‐‐submucosa; fourth hypoechoic layer‐‐circular smooth muscle; fifth thin hyperechoic layer‐‐intermuscular connective tissue; sixth hypoechoic layer‐‐longitudinal smooth muscle; seventh hyperechoic layer‐‐adventitia.
