AIM: The aim of this paper was to demonstrate the usefulness of magnetic resonance imaging (MRI) for detecting the ability of compression material in narrowing superficial and deep veins in the lower extremity.
METHODS: MRI of the legs was performed in one healthy volunteer and in 11 patients with CEAP C2-C4 without and with different kinds of compression devices. The cross section area of superficial and deep veins was measured by planimetry in mid-calf and mid-thigh slices. The interface pressure of compression was measured at the same level.
RESULTS: Examples are presented showing that the narrowing of veins does not only depend on the exerted pressure but also on the body position and the resulting distortion of the tissue. In the prone and the standing position deep veins may show a greater reduction of the cross section area than in superficial veins.
CONCLUSION: MRI is a powerful method to assess venous narrowing by external compression. Especially in the standing position new insights regarding the effects of different compression devices may be expected.
