Figure 6.

Abdominal CT angiography using photon-counting computed tomography. The figure shows advanced multiplanar reconstructions without and with MIP algorithm of a distal abdominal aorta and ilio-femoral arterial axes derived from a photon-counting CT (Scanner: NAEOTOM Alpha, Siemens) acquisition (A,B right; C,D left). The projection start in the abdominal aorta carrefour and end in the right/left common femoral artery. There are massive calcifications along the common iliac arteries; however, both MPRs (A,C) and MIPs (B,D) are so sharply defining the edges of the structures that lumen assessment is not compromised (arrowheads).
