Does densitometer-computer analysis of angiographic images quantify aortic atheromas and indicate local cholesterol concentration?
Does densitometer-computer analysis of angiographic images quantify aortic atheromas and indicate local cholesterol concentration?
Densitometer-computer analysis of angiographic images can provide an index indicative of local cholesterol concentration in aortic atheromas.
Answers are grounded in this paper and cite their sources.
May support angiographic indexing of aortic atheroma cholesterol; hypothesis-generating and requires prospective validation before clinical use.
SummaryRaised aortic atheromas can be quantitated by densitometer-computer analysis of edge irregularity on angiographic shadows. Combined measurement of edge irregularity and variation in cross-sectional density provides an angiographic index indicative of local cholesterol concentration in aorta walls and atheromas.
