Methods: We conducted a review of domestic and international imaging techniques used for the diagnosis of neonatal arterial ischemic stroke (NAIS), including magnetic resonance imaging (MRI), cranial ultrasound (CUS), computed tomography (CT), and digital subtraction angiography (DSA), along with literature on their related advanced technologies. We provide an overview of various imaging techniques and their corresponding imaging manifestations for NAIS lesions. Results: Different imaging modalities offer distinct advantages in disease diagnosis. Diffusion-weighted imaging (DWI) is the most sensitive for detecting acute-stage NAIS, while advanced imaging techniques such as diffusion tensor imaging (DTI) and arterial spin labeling (ASL) provide comprehensive diagnostic capabilities for this condition. Conclusions: Magnetic resonance imaging is the gold standard for diagnosing NAIS;novel imaging techniques can provide additional radiological information for clinical practice.展开更多

文摘Negative air ions(NAIs)in indoor environments have been suggested to positively impact human health by effectively reducing particulate contamination and gaseous pollutants,as well as inhibiting the growth of microorganisms,bacteria and viruses.This study investigates the common ionizers with different module types,and the mechanism of NAIs for enhancing indoor air quality,as well as the positive and negative impacts on human health.The association between NAI concentrations and human health outcomes is examined,and alternative measures to balance beneficial and unavailing effects are investigated.While NAIs demonstrate efficacy in removing particulate pollutants,alleviating depression,enhancing cognitive function and even stimulating sympathetic activity,it is pertinent to acknowledge the presence of contradictory findings concerning their effects on cardiac autonomic function and respiratory physiology.To address this complexity,it is imperative to consider alternative measures that strike a balance between the beneficial and unavailing effects of NAIs.These measures can encompass a general assessment of the characteristics of particulate pollutants,a strategic selection of ionizer technologies,and adherence to the recommended optimal concentration thresholds of NAIs.
