What is Discrimination of Human Arterial Pathology by Computer Processing of Angiograms for Serial Assessment of Atherosclerosis Change about?

Femoral angiograms were made in 21 cadavers under conditions which simulated clinical films. Then these arteries were excised, laid open, and color photographed along side of corresponding casts of the arterial lumen. Twenty-seven segments, 5 cm long, were classified as exemplary of normal vessel, uncomplicated stenosis, or hemorrhagic ulceration. The corresponding angiogram images of these arterial segments were digitized and processed to yield outlines of the vessel edges, and from these, computer measures were developed which described how these outlines deviated from ideal ones. Six of these measures were selected by means of stepwise discriminant analysis to distinguish the type of disease along the 27 exemplary segments, and 96% were correctly class&& Computer processing of angiograms shows promise for discriminating the nature of atherosclerotic lesions. We have developed a technique which involves computer processing of angiograms to assess the degree of atherosclerosis (I, 2). This method was designed primarily for clinical use; but to provide adequate standardization it has been calibrated against autopsy findings using the International Atherosclerosis Project (IAP) grad
