Fig. 6

A 51-year-old male patient with diabetes and intermittent right lower limb pain underwent DE-CTA of the lower limb arteries with popliteal artery monitoring. (a) Show abdominal lliac segment. (b) Show femoral popliteal segment. (c) Show lower knee segment. (d) Show maximum intensity projection of peripheral arteries. The image quality was excellent, with significantly enhanced contrast and clear visualization of the vessels below the knee. Both physicians diagnosed severe stenosis and occlusion of the right posterior tibial artery as indicated by the arrow. The subjective scores were AIS: 5, FPS: 5, LKS: 5, with a lower limb vessel grading of 5. The diagnostic confidence levels were AIS: 3, FPS: 3, LKS: 3.
