[Diagnosis and differential diagnosis of breast cancer using intravenous DSA]

Intravenous DSA of the breast is a new, hardly invasive, method for demonstrating carcinomas of the breast and for differentiating these from benign lesions. Carcinomas show distinct tumour-staining during the capillary phase, although the criteria which are used on conventional angiography are not recognisable. Semi-malignant tumours show feeble staining. Benign diseases such as fibro-adenomas and focal sclerosing adenosis are not demonstrated by I-V DSA. The indication for intravenous breast DSA is for the clarification of suspicious findings where less invasive methods, such as mammography and cytology, have failed to give a definitive diagnosis.
