Therefore, this pilot diagnostic accuracy study aims to evaluate the sensitivity and specificity of RTMUS, using POCUS as the gold standard for the diagnosis of pulmonary oedema.

The B-mode sonographic findings of articular effusion, synovial hypertrophy and capsular bulging, coupled with the microvascular mapping with colour Doppler of the sternoclavicular joint, have been crucial to optimising the pharmacological approach in clinical practice.
