Positioning of the legs is an important consideration during runoff angiograms. The legs should be positioned:

In runoff angiograms, proper positioning of the legs is crucial for obtaining clear and accurate images of the lower extremity vessels. When the legs are positioned close together and stationary without tight straps, it allows for a more natural alignment of the vascular anatomy and reduces the risk of movement artifacts during image acquisition. This positioning also facilitates better access to the inguinal region and ensures that the arteries and veins are adequately visualized without obstruction.

Keeping the legs together, yet stationary, helps maintain a consistent distance between the imaging device and the area of interest, which is vital for the quality of the diagnostic images. Additionally, avoiding tight straps prevents any compression of vessels that could lead to compromised blood flow or distortion of vascular structures, enhancing the diagnostic efficacy of the angiogram.

On the other hand, other positioning options, such as using tight straps or keeping the legs apart, can lead to suboptimal imaging conditions. Tight straps may impede circulation or create artifacts, while positioning the legs apart could alter the alignment of key anatomical structures, complicating the interpretation of the angiogram. Thus, the chosen positioning of the legs is essential in achieving high-quality imaging results in vascular interventions.
