*Additional Doppler required: L1, above the joint line; L2, at the joint line; L3, below the joint line.
Table 1: Transducer position in the sagittal, coronal and axial planes for ultrasound scanning of the elbows. Standard anatomic descriptions for the level of transducer position: L1 for proximal articular surface (above the elbow joint), L2 for joint space and L3 for distal articular surface (below the elbow joint).
