Wound management is a challenging and costly problem that is growing in importance as people are living longer. Instrumental methods are increasingly being relied upon to provide objective measures of wound assessment to help guide management. Technologies that employ near-infrared (NIR) light form a prominent contingent among the existing and emerging technologies. We review some of these technologies. Some are already established, such as indocyanine green fluorescence angiography, while we also speculate on others that have the potential to be clinically relevant to wound monitoring and assessment. These various NIR-based technologies address clinical wound management needs along the entire healing trajectory of a wound.

Near Infrared Imaging for Angiography in Diabetic Patients With Peripheral Artery Disease

“…В недавние годы появились работы по оценке ишемии нижних конеч-ностей у пациентов с заболеваниями артерий нижних конечностей, где показаны обнадеживающие резуль-таты применения ФАГ в данной области [8][9][10][11].…”

Novel Optical Techniques for Imaging Microcirculation in the Diabetic Foot

“…Based on existing literature [16][17][18][19][20], and our research and clinical experience, four novel optical imaging techniques were selected as topic in this review, as these can be used to measure the microcirculation in tissue: LDPI, LSCI, PAI, and HSI. For each technique a global technical background will be given (part a).…”

“…While various reviews [16][17][18][19][20] have been published in recent years focusing on optical techniques to assess microcirculation, these reviews only focused minimally on microcirculation for diabetic foot ulcers [16][17][18][19][20]. Microcirculatory assessment for diabetic foot ulcers, however, poses unique challenges, different from other vascular disease areas; these include the combination of the presence of an open wound, local microvascular changes (including arteriovenous shunting), potential presence of macrovascular disease, calcifications, infection, edema, and poor collateralization [15].…”

SnapshotNIR: a handheld multispectral imaging system for tissue viability assessment

“…There are several technologies, some of them optically based, that are used for wound assessment and monitoring. 2 However, the ability to survey large areas of tissue in a single image and to acquire that image completely non-invasively in a matter of seconds makes red -near infrared spectral imaging stand-out compared to competing methods. In addition to wound assessment and management, local hemoglobin oxygenation assessment during surgical reconstruction of tissue is important.…”
