摘要: PURPOSE To evaluate the incidence and locations of soft tissue enhancement on time-resolved two-dimensional projection magnetic resonance angiography (MRA) calf foot. MATERIALS AND METHODS Time-resolved MRA knee, calf, foot, performed at 1.5 Tesla using head coil, was retrospectively reviewed in 326 patients. Soft foot identified graded by blinded review. Subsequently, patient medical records were to determine presence or absence diabetes, cellulitis, gangrene, ulceration neuropathic joints. RESULTS Enhancing spots 228 For those feet without clinical abnormalities, diabetic patients had an average 1.2 enhancing per while nondiabetics only 0.6 (P < 0.001). Higher-grade lesions more prevalent diabetics heavier Of 64 with follow-up, 8 (13%) developed cellulitis (N = 4) location spot, including 5 3 nondiabetic CONCLUSION Pedal frequently occurs gadolinium (Gd):MRA feet. The etiology is uncertain, but high frequency observation progression cellulitis/ulceration suggest this may identify sites subclinical pedal injury.
