“…There are multiple methods to locate perforating vessels in the flap, such as CTA, Doppler ultrasound, and indocyanine green (ICG) fluorescence angiography (ICG-FA). According to Kolacz et al, an ideal method in a clinical setting meets the following conditions: noninvasiveness, simplicity, repeatability, the ability of peroperative assessment, and low cost [7]. (DIRT is a noninvasive monitoring technique, unlike ICG-FA and CTA, and it is used in clinical medicine as a mechanism to measure skin temperatures [8].…”

“…The method of static thermography does not render an unequivocal indication of the location of the perforators [7]. Several studies of dynamic thermography [7,9] are available, which include different methods for obtaining a temperature difference to reveal the dynamic properties. The flap was stimulated with high and low temperatures.…”

“…The flap was stimulated with high and low temperatures. The number of hot spots was smaller when a heat stimulation was used in contrast to cold stimulation [7]. The area was cooled down 5 • C-6 • C or heated up by 5 • C-6 • C to avoid damage by burning the tissue [7].…”

In the modern world, one-third or more of breast cancer patients still undergo uni-or bilateral mastectomy. Breast cancer patients, in general, have a good prognosis and long-term survival. Therefore, the treatment must not only focus on survival but also on the quality of life. Breast reconstruction with an autologous free deep inferior epigastric artery perforator (DIEP) flap is one of the preferred options after mastectomy. A challenging step in this procedure is the selection of a suitable perforator that provides sufficient blood supply for the flap to prevent necrosis after anastomosis. In this pilot study, the possibilities for dynamic infrared thermography (DIRT) are investigated to select the best suitable perforator. The measurements are done with external cooling in the preoperative stage to accurately predict the location of the dominant perforators. During the surgery, in the peroperative stage, measurements are done for mapping the influence of a specific perforator on the perfused areas of the abdominal flap. Perforators are sequentially closed and opened again to map the influence of that perforator on the vascularization of the flap, visualized with the help of the thermographic camera. The acquired steady-state thermal images could help decide which parts of the abdominal flap to use for the reconstruction so that the chance of (partial) necrosis is reduced. In the postoperative stage, DIRT could visualize the arterial and or venous thrombosis before they become clinically obvious as (partial) necrosis. At present DIRT seems to be a valuable investigation for the pre-, per-, and postoperative phases of DIEP-flap reconstructions. Large, high-quality clinical studies are needed to determine its definitive role.

“…In order to see what can be considered the best one for the interested community on promote the union of effort for better use of IR images on diagnosis, data from these two types of acquisitions, obtained by our group, are available in a database of breast thermal images, named Database for Mastology Research with Infrared Image-DMR-IR [27], and can be used by researchers on breast infrared images. This, as far as we known, have never be done before for breast diagnosis (for locating perforating vessels in breast reconstruction surgery the use of cold and hot stimulation was used and compared with static thermography by Kołacz et al [16]). In both, the patient attempts the common preparation and we used to ask them for, before capturing the images, pass for acclimatization in a room with controlled temperature (between 20 and 22°C for 10 min) with arms raised over the head and with the breast naked.…”

This chapter presents some developments and researches on using breast infrared images in Brazil (Visual Lab group of the Federal Fluminense University). These researches focus on comparing protocols for data acquisition using a FLIR SC 620 infrared (IR) camera; preprocessing the acquired data (using operations such as region of interest or ROI extraction, image registration and some other operations to prepare the images or thermal matrices to be used in computations); 3D reconstruction and, diagnostic recommendations from the IR data. These are steps for development of computer tools for screening breast diseases, mainly, to be used on public health system (named in Brazil: "Sistema Único de Saúde"-SUS). After experimentations and comparisons among the diversity of recommendations and ways of data acquisition reported in the literature, we propose a new protocol to IR data capture and storage. With these, we developed a web site that can be used

Objectives: The aim of this study is to investigate the different approaches to thermal challenges, both cold and warm, used in dynamic infrared thermography for reconstructive surgery, and explore whether it affects the success of preoperative perforator mapping. Material and Methods: Literature was collected from OVID Medline, Embase, PubMed and Cochrane. The references of the full-text articles located from the original search were also appraised. Thirteen articles were extracted for the final qualitative analysis. A systematic review was then conducted following the PRISMA guidelines. Results: Thirteen articles looked at a cold challenge, which included airflow cooling, direct contact cooling and evaporative based cooling. Two articles investigated warm challenges. One paper used no challenge, suggesting it unnecessary with a highly sensitive camera. All cold challenges were positively supported by a high level of flap perfusion success, and/or a high level of correlation with other forms of investigation. Conclusions: Cold challenges were overall superior to no challenge and warm challenges; however, this conclusion is limited by the small participant size, the possibility of detection bias, and poor methodology detailing. Airflow cooling - specifically, using a desktop fan to blow air for two minutes - was noted to likely cause the least discomfort due to a low cooling capacity yet simultaneously maintain effectiveness and allow for a uniform cooling application. Warm challenges showed less conclusive results and were restricted by lack of studies. This topic would benefit from larger scale studies that compare multiple approaches whilst using standardized equipment to eliminate confounding factors.
