Physician interpretation of ultrasound in the evaluation of ankle edema.

Objectives: The aim of this study was to assess inter‑ and intra‑observer agreement of detection and grading of oedema measured by vascular physicians using ultrasonography.

Method: In this observational study, three investigators read 113 videos of ultrasonography of the medial lower leg of 77 patients using a 15-18 MHz linear probe and reported whether oedema was present or not and, if present, to what extent. The videos were selected by the coordinator and sent every two months for a period of six months to the three investigators.
