MRI links long-COVID brain fog to lung function

MRI shows that lower pulmonary gas exchange in the lungs of long-COVID patients may be associated with cognitive symptoms.

November 26, 2024

Individuals in the study were plotted with the x-axis being rank of pulmonary gas exchange. The black dots show the pulmonary gas exchange ratio (red blood cell to tissue plasma ratio, RBC:mem) on the left y-axis and the blue dots are the cognition scores on the right y-axis. Gas exchange maps of three representative patients from a low, medium, and high pulmonary gas exchange. Image courtesy of RSNA.

FAPI-PET/CT superior to FDG-PET/CT in liver cancer patients

Ga-68 FAPI-PET/CT imaging appears superior to FDG-PET/CT for assessing hepatocellular carcinomas. In a large prospective trial, the approach was more accurate – enough so that it could possibly replace FDG-PET/CT in the future.

Theranostics cost-effective in men with mCRPC

Using theranostic radionuclides such as Ra-223 or Lu-177 to treat men with metastatic castration-resistant prostate cancer (mCRPC) is more cost-effective in the long term than traditional chemotherapy and radiotherapy, suggests a study in this session.

Low-dose CT ties emphysema to mortality in previous smokers

By Amerigo Allegretto

Study findings highlight the clinical relevance of CT-diagnosed emphysema.

September 9, 2025

Representative axial images of mild, moderate, and severe emphysema at baseline low-dose CT (LDCT). Participants were categorized as having no emphysema or mild, moderate, or severe emphysema. When present, emphysema was mild if no distinct regions of reduced attenuation were visible on the CT scan, but vascular splaying indicates parenchymal expansion, or if only occasional discrete low-attenuation regions were observed. Moderate emphysema was defined by the presence of identifiable low-attenuation regions affecting less than half of the lung parenchyma, whereas severe emphysema was defined by the presence of identifiable low-attenuation regions that involved more than half of the lung parenchyma. A scoring system from 0 to 3 was applied, corresponding to none, mild, moderate, and severe emphysema, respectively. Yellow circle indicates the extent of emphysema. (A) A 67-year-old man with mild emphysema at baseline LDCT in 2002. Baseline LDCT scan shows vascular splaying, suggesting parenchymal expansion due to emphysema and occasional discrete low-attenuation regions. The participant ultimately died of cardiovascular disease 15.4 years (184.2 months) later. (B) A 69-year-old man with moderate emphysema at baseline LDCT in 2007. The participant died of cardiovascular disease 1.8 years (21.9 months) later. Identifiable low-attenuation regions affected less than half of the lung parenchyma. (C) An 85-year-old woman with severe emphysema at baseline LDCT in 2006. After 5.5 years (65.5 months) of follow-up, the participant died due to chronic obstructive pulmonary disease–related causes. Identifiable low-attenuation regions involved more than half of the lung parenchyma.
