The results of angiographic studies of abdominal masses.

This study reveals the continuing great viability of angiography in the investigation of abdominal masses. It is a fundamentally important procedure within the context of presurgical evaluation. Certain points should be underlined. - The radiological definition of the histological nature of an abdominal mass during angiography remains difficult, practically impossible in certain regions. - Borrowed vascularizations still pose complex diagnostic problems at different levels. - The benefit of angiography should be compared with other modern radiodiagnostic methods, especially the less aggressive ones. - The importance of each of these points has led us to develop them separately: - The diagnostic reliability of angiography in abdominal masses (from anatomico-radiological correlations). To be published - The borrowed vascularisation of abdominal masses. To be published - The tomodensitometry of abdominal masses. To be published - Diagnostic strategy in case of an abdominal mass. To be published.
