How reliable are geometric coronary measurements? In vitro and in vivo validation of digital and cine recently been performed [4–13]. For the purposes of both scientific research and clinical practice, the question arises whether each system requires separate validation and which of the geometric parameters is most suitable for the purpose of quality control.

Why and how should QCA systems be validated? will be clear that extensive validation studies need to be carried out to demonstrate the strengths and weaknesses, as well as the clinical validity of such analytical packages. The more we learn about QCA, the more it becomes clear that such validation studies must be well designed, properly carri

How reliable are geometric coronary measurements? In vitro and in vivo validation of digital and cinanalysis represents an effective and the most readily applicable approach to evaluate the severity of coronary artery stenoses. An increasing number of digital and cinefilm-based analysis systems is now commercially available [2,3] requiring critical evaluation and a series of validation studies hav

Validation of videodensitometry in the assessment of stenosis phantoms: an in vitro and in vivo studf the measurements with edge-detection, however, can be impaired by the presence of eccentric lesions or of lesions of complex lumen geometry. Under these conditions densitometry has a potential advantage because of its independence from the shape of the lesion.
