Multi imaging approach with low field MRA in diabetic foot ulcer: hospital based study

The aim of study was to assess the usefulness of non-invasive imaging in patient of diabetic foot ulcer with low field MRA and determine the severity and extent of lower extremity arterial disease in diabetic patients with poor socio economic status. The present study is based on 38 patients who were referred to Department of Radiology with complaint of non-healing ulcer of lower limb of more than 6 weeks duration. The patients were subjected to plain radiographs, Duplex scanning with color flow imaging and MR angiography (non contrast enhanced). The modalities were used to detect vascular calcifications, osteomyelitis, bone resorption, deformities, thickening of arteries, plaques, spectral waveforms, collaterals. MRA was used to assess subjective calibre of vessels and presence of stenosis. The patients were categorised according to age and a note of ulcer duration made. Grade of ulcer was determined (wagner’s criteria) and note was made of severity of stenosis (cossman). Radiographs assessed bony destruction and vascular calcification. Doppler assessed degree of stenosis and vascularity. MRI gave a road map of vascular integrity. Integration of the tests provided a satisfactory diagnostic protocol to decide future prognosis and assessment of advancement of disease process. The data was subjected to calculation of mean, standard deviation and Pearson’s chi square test. p value
