TRICKS Magnetic Resonance Angiography at 3-Tesla for Assessing Whole Lower Extremity Vascular Tree in Patients with High-Grade Critical Limb Ischemia: DSA and TASC II Guidelines Correlations
Figure 1
A 60-year-old man with unhealed ulcers over the left heel region for 4 months. (a) T-MRA with MIP reconstruction at 36 s after contrast medium injection demonstrating peak arterial enhancement of the right distal run-off station with clear depiction of infrapopliteal and pedal arteries without venous overlay. The left leg vessels are not poorly opacified. (b) T-MRA at 42 s time frame demonstrating peak arterial enhancement of the left leg with multiple significant stenoses (arrows) in the left posterior tibial artery and dorsalis pedis and nonopacification of planter artery. The right leg is obscured due to prominent venous contamination. Without a time-resolved approach, clear depiction of infrapopliteal and pedal vessels would have been difficult due to discrepant arterial inflow.
