Computer Prediction of Restenosis Following Peripheral Angioplasty

The purpose of this study is to develop a computer program that might be able to accurately assess the risk of artery re-narrowing following angioplasty or stenting based on computer images. After angioplasty (a procedure to re-open narrowed or blocked blood vessels) the patients will have extra images taken in order to assess the results of the procedure; which will then be used to see whether or not these images can help predict outcomes such as the patient having to come back to the hospital to have the procedure done again.
