According to the results of this study, 99mTc sestamibi scintigraphy appears to be a feasible and promising method in the evaluation of free muscle flap viability and complications. On the other hand, to demonstrate any impact on management or patient outcome, further evaluation of 99mTc sestamibi imaging, including comparative studies with different established methods in a larger patient population, is highly recommended.

Studies have extensively analyzed the effect of hyperglycemia on 18 F-FDG uptake in normal tissues and tumors. In this study, we measured SUV in the brain, liver, and blood pool in normoglycemia, hyperglycemia, and hypoglycemia to understand the effect of blood glucose on 18 F-FDG uptake and to develop a formula to correct SUV. Methods: Whole-body 18 F-FDG PET/ CT images of adults were selected for analysis. Brain SUV max , blood-pool SUV mean , and liver SUV mean were measured at blood glucose ranges

Since healing of the stump was seen in all cases, outcome was correctly predicted by scintigraphy. This preliminary study supports the use of (99m)Tc-sestamibi scan in selecting the optimal amputation level consistent with subsequent stump healing.
