Remote metastasis detection by video thermometry: A promissing preclinical study

Abstract

The thermometric video image (VTM) can guide the search for distant metastases, once the vascular architecture is known, identifying, by segmentation, the tumor thermal impression and a similar pattern at a distance. Thus, suspicious areas can be better investigated, improving the postoperative prognosis. In this study, it was possible to observe the assertive capacity of video thermometry in identifying distant metastases and breast tumors in female dogs, not palpable or visible to the naked eye, in relation to conventionally used techniques. It was also possible to identify textures with anatomical limits, from emboli to early formations of carcinomas, adenocarcinomas and adenomyoepithelioma. It was also possible to find non-neoplastic changes such as dermatitis, lipoma, hyperplasia and breast cysts. it can be concluded that the video thermometry (VTM) technique was capable of identifying distant metastases from the primary tumor and other benign alterations with great precision. However, for this to be possible, it is essential that the processing be carried out by SaMD (Software as a Medical Device), with tools capable of identifying patterns and thermal signatures, just like the algorithm, thus increasing the efficacy of the technique.
