Abstract:

Aim: was to evaluate pedal vascularisation in diabetic patients with using contrast MR-angiography.

Material and methods: 23 patients (15 male, 8 female; mean age 56±14,6) with suspicion on osteomyelitis (OM) underwent MR-angiography (Gadobutrol 15ml). Imaging analysis included blood-flow's speed, vascular architectonic's condition and character of contrast's accumulation, microcirculation was especially estimated. Results were compared with white blood cells-scan in identification of pyoinflamation. Osteomyelitis was verified according to operations in all cases.

Results: all patients were divided in 3 groups: neuropathic (n=9; 39,0%), neuroischemic (n=10; 43,5%), ischemic (n=4; 17,5%) forms of diabetic foot. First-pass MR-angiography detected significant delay in contrast's arrival in ischemic group. There were no significant differences between values of neuropathic and neuroischemic forms of diabetic foot. There were no pedal vessels in patients in ischemic and neuroischemic groups. Contrast MR-angiography revealed three types of contrast distribution in soft tissues: uniform, local increase and local absence. Osteomyelitis was characterized as diffuse enhanced contrast accumulation in all cases.

Conclusions: MRI blood vessel imaging is a promising and valuable method for examining peripheral arterial changes in diabetic foot and may be useful for treatment planning in different forms of diabetic foot.
