Visualization of stent-grafts allows guidance and deployment to be assessed. Detection by negative contrast can be confused with other sources of hypo-intensity. A modified version for SGM is presented for positive visualization without compromise in resolution. This and its application by post-processing allows the information from both contrasts to be used without registration.
