摘要光声成像技术利用"光进声出"的原理对肿瘤组织光学吸收体进行非侵入性成像，结合了光学成像高对比度和声学成像高穿透性的优点，无创且无电离辐射。但目前光声成像研究仍局限于实验室，该技术可用于皮肤原位黑素瘤及非黑素瘤性皮肤癌的检测及前哨淋巴结成像，并实现黑素瘤循环肿瘤细胞的检测与实时激光消融治疗，联合外源性显影剂可实现多功能成像和治疗。本文对光声成像技术在皮肤肿瘤的临床前实验进行综述，以期早日促进临床应用的转化。

abstractsPhotoacoustic imaging is a kind of non-invasive technology without ionizing radiation that can be used to image optical absorbers in tumor tissues according to the principle of "light in and sound out". It has the advantages of high contrast of optical imaging as well as high penetrability of acoustic imaging. However, current researches on photoacoustic imaging are still limited in the laboratory. This technology can be used for detection of cutaneous melanoma in situ and non-melanoma skin cancer, sentinel lymph node imaging, detection and eradication of circulating tumor cells by combining real-time laser ablation technique, and versatile imaging and treatment with the aid of exogenous imaging agents. This review summarizes preclinical experiments about photoacoustic imaging technology in skin tumors, with a view to promoting its clinical application at an early date.
