The low detection rate of Mycobacterium tuberculosis in clinical practice leads to a high rate of missed diagnosis for pulmonary tuberculosis (PTB). As a noninvasive, high-resolution, real-time imaging technology, polarization-sensitive optical coherence tomography (PS-OCT) may be feasible for the rapid identification of pathological feature. This study aimed to explore the feasibility of using PS-OCT to identify pathological features of PTB. In the experiments, PTB samples containing some surrounding lung tissues were imaged using PS-OCT. It is demonstrated that PS-OCT images showed good consistency with the corresponding pathological images and were able to identify PTB-related characteristic pathological regions. We think PS-OCT can serve as an effective supplement for the diagnosis of PTB, enabling rapid and accurate diagnosis, and aiding in the understanding of the pathological characteristics and pathophysiological processes of PTB.
