[MR angiograph of peripheral arterial injury in patients with diabetic feet].
OBJECTIVE
To explore the diagnostic value of MRI blood vessel imaging in diagnosing peripheral arterial injury in diabetic patients.


METHODS
Nineteen diabetic patients with suspected peripheral artery injuries underwent MRI blood vessel imaging. 3D contrast enhanced-MRA (CE-MRA) was performed in the area from the articular genu to the ankle mortise to identify peripheral artery injury. The extent of blood vessel stenosis was graded. The correlation between blood vessel stenosis and clinical features was analyzed.


RESULTS
All target arteries were well demonstrated. Out of a total of 152 arterial segments, 121 segments showed normal or mild stenosis, 17 showed moderate stenosis, 9 showed severe stenosis, and 6 showed occlusion. The extent of stenosis was correlated with clinical features.


CONCLUSIONS
MRI blood vessel imaging is a promising and valuable method for examining peripheral arterial changes in patients with diabetic foot problems.
