Perivascular spaces may be associated with cardiovascular and dementia risks and these authors sought to determine if they are also associated with atherosclerosis. Thus, perivascular spaces were assessed in more than 700 patients and correlated with race, age, and cardiovascular risks. They were found to be more common in older hypertensive patients and the presence of carotid artery plaques strongly and consistently predicted their presence.

CT findings in 27 nontreated patients with oral squamous cell carcinoma were correlated with genomic analysis. Tumor enhancement correlated with presence of vascular endothelial growth factor while epidermal growth factor correlated with mass effect and perineural invasion. Thus, some CT findings may reflect genomic biomarkers.
