Myofascial pain syndrome(MPS)is a common skeletal muscle pain and dysfunction disorder characterized by the presence of myofascial critical pain points(MTrPs).At present,the clinical diagnosis of this disease mainly depends on palpation,but its positioning reliability of the shock pain point is low.Ultrasonographic techniques have been used to distinguish between active latent MTrPs,but these studies do not adequately address their underlying anatomical structures.MRI remains the standard method for skeletal muscle imaging.Using the signal characteristics of each sequence of MRI and dynamic enhanced scanning,we can not only make the disease diagnosis of MPS,but also obtain the information of local structure more clearly.This review paper reviews the current studies of myofascial pain syndrome(MPS).
