Abstract
Diabetic foot disease is a severe complication of diabetes mellitus that can lead to infection, ulceration, and amputation. Accurate assessment of the extent of infection is crucial for effective treatment. Advancements in technology, such as thermal imaging, have shown promise as bedside adjuncts in diabetic foot assessment. This report of two cases compares the efficacy of thermal imaging and the gold-standard magnetic resonance imaging (MRI) in evaluating the extent of diabetic foot infections in two patients. Thermal imaging and MRI were used preoperatively to assess diabetic foot infections. Thermal imaging showed a reduced temperature around the ulcer, correlating with necrotic tissues; however, it lacked the comprehensive detail provided by MRI. MRI accurately delineated the depth and extent of infection, identified potential bone involvement, and detected subtle soft tissue changes, features that thermal imaging lacked. MRI remains indispensable for its superior ability to provide detailed anatomical information and assess the full extent of infection, which is critical for surgical decision-making and long-term management. The complementary use of both modalities may enhance diagnostic accuracy, with thermal imaging serving as an accessible preliminary tool and MRI providing the necessary depth for complex cases.
