Phototherapy, also known as photobiological therapy, is a non-invasive and highly effective physical treatment method. Its broad use in clinics has led to significant therapeutic results. Phototherapy parameters, such as intensity, wavelength, and duration, can be adjusted to create specific therapeutic effects for various medical conditions. Meanwhile, Magnetic Resonance Imaging (MRI), with its diverse imaging sequences and excellent soft-tissue contrast, provides a valuable tool to understand the therapeutic effects and mechanisms of phototherapy. This review explores the clinical applications of commonly used phototherapy techniques, gives a brief overview of how phototherapy impacts different diseases, and examines MRI's role in various phototherapeutic scenarios. We argue that MRI is crucial for precise targeting, treatment monitoring, and prognosis assessment in phototherapy. Future research and applications will focus on personalized diagnosis and monitoring of phototherapy, expanding its applications in treatment and exploring multimodal imaging technology to enhance diagnostic and therapeutic precision and effectiveness.

磁共振成像目前在评估和监测光疗疗效方面的作用

光疗又称光生物疗法，是一种非侵入性、高效的物理治疗方法。其在临床的广泛应用带来了显着的治疗效果。可以调整光疗参数，例如强度、波长和持续时间，以针对各种医疗状况产生特定的治疗效果。同时，磁共振成像（MRI）以其多样化的成像序列和出色的软组织对比度，为了解光疗的治疗效果和机制提供了有价值的工具。这篇综述探讨了常用光疗技术的临床应用，简要概述了光疗如何影响不同的疾病，并探讨了 MRI 在各种光疗场景中的作用。我们认为 MRI 对于光疗中的精确定位、治疗监测和预后评估至关重要。未来的研究和应用将集中于光疗的个性化诊断和监测，扩大其在治疗中的应用，并探索多模态成像技术，以提高诊断和治疗的精度和有效性。
