Traumatic brain injury (TBI) is a significant problem worldwide and neuroimaging plays a critical role in diagnosis and management. Recently, perfusion neuroimaging techniques have been explored in TBI to determine and characterize potential perfusion neuroimaging biomarkers to aid in diagnosis, treatment, and prognosis. In this article, computed tomography (CT) bolus perfusion, MR imaging bolus perfusion, MR imaging arterial spin labeling perfusion, and xenon CT are reviewed with a focus on their applications in acute TBI. Future research directions are also discussed.

Microthrombus formation is associated with COVID-19 severity; however, the detailed mechanism remains unclear. In this study, we investigated mouse models with severe pneumonia caused by SARS-CoV-2 infection by using our in vivo two-photon imaging system. In the lungs of SARS-CoV-2-infected mice, increased expression of adhesion molecules in intravascular neutrophils prolonged adhesion time to the vessel wall, resulting in platelet aggregation and impaired lung perfusion.

Background And Purpose: In acute ischemic stroke, the amount of "local" CBF distal to the occlusion, i.e. all blood flow within a region whether supplied antegrade or delayed and dispersed through the collateral network, may contain valuable information regarding infarct growth rate and treatment response.

This study aimed to investigate the effects of silicone implants on the incidence of breast cancer in rats, as well as their impact on immune surveillance mechanisms. Female SD rats were divided into three groups: a Placebo Surgery Group (PSG), a Thoracic Implant Group (TIG), and a Back Implant Group (BIG). Following the corresponding surgical procedures, we measured Secretoglobin Family 2A, Member 2(SCGB2A2) and Mucin-1 (MUC1) antigen levels using ELISA, and statistical analyses were conducted to evaluate immune responses.

Article Synopsis
- Hyperacute cardiac CT is more effective than transthoracic echocardiography in detecting intracardiac thrombus, but its routine use is limited due to costs and risks.
- A study of 1,136 ischemic stroke or TIA patients found that longer arterial input function (AIF) dispersal times correlate with the presence of thrombus and worse outcomes, with a specific cutoff of 33 seconds indicating higher risk.
- The findings support using AIF dispersal measurements to help identify patients who may benefit from cardiac imaging, potentially optimizing resource use in stroke management.
