Advances in multimodal imaging of lung injury

Lung injury is caused by various physical and chemical damages that lead to the destruction of the structural integrity or dysfunction of the lungs, resulting in a series of symptoms or diseases. Given its complex clinical manifestations and varying degrees of severity, accurate diagnosis and evaluation of lung injury are particularly crucial for the selection of appropriate treatment programs. Imaging examination, including chest radiography, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and so on, are vital tools for diagnosing lung injury and assessing its functional or morphological changes and progression. With the advancement of medical imaging technology, multimodal imaging offers a more diverse assessment of lung injury. This article reviews the progress of multimodal imaging in lung injury, encompassing routine and new imaging techniques, multimodal fusion imaging, and the application of AI, all of which can provide valuable references for clinical diagnosis and management of lung injury.
