Abstract Introduction While visual assessment is the standard for burn severity evaluation, new technologies are attempting to increase objectivity. Burn depth assessment accuracy improves over time as the appearance changes, but earlier diagnosis potentially leads to prompt treatment and shorter recovery. Laser Speckle Imaging (LSI), FDA approved for grading burns, is typically done 72hrs after injury. Spatial Frequency Domain Imaging (SFDI), a novel technology only tested in animal burn models, uses multiple wavelengths of patterned light to quantify tissue absorption (hemodynamics) and scattering (structure). SFDI has shown the potential to differentiate burns as early as 24hrs postburn by measuring scattering (µs’) changes due to collagen damage. Here, we examine SFDI burn severity assessment in clinical patients, and compare against LSI and clinical assessment. Methods 5 burn cases were imaged with LSI and SFDI approximately 24 and 72hrs postburn. The clinician was blinded to imaging results and made diagnoses on their standard of care. Results One patient received no surgical intervention, one received excision and xenograft, and two received excision and autograft. An autograft was recommended for one patient, but not performed due to preexisting conditions. SFDI measurements at 24hrs showed low µs’ values in regions that eventually required autografts, and high µs’ in burns that did not. While clinical decisions were made no earlier than 72hrs postburn, µs’ maps at 24hrs postburn were able to illustrate severity in these regions. In 2 of 3 autograft cases, LSI was unable to determine the severity until 72hrs postburn. Conclusions Here, we compared SFDI to LSI in a clinical setting to quantify burn wound severity. Similar to animal models, SFDI was demonstrated to accurately characterize severity earlier than the perfusion-based LSI. This is likely due to sensitivity of µs’ measured by SFDI to the structural changes in damaged collagen (i.e., zone of coagulation) that occur immediately postburn.
