[Intravenous arteriography with xerography: a non-invasive method for the demonstration of peripheral vessels (author's transl)].
Acceptable arteriograms of the extremities can be obtained by rapid manual injection of contrast into a cubital vein, using a xeroradiographic technique. The indications and value of the method have been demonstrated in 62 examinations. The new technique constitutes a non-invasive arteriographic method suitable for demonstrating limited vascular lesions in the extremities.

[Transvenous xero-arteriography of the limbs (author's transl)].
Well-visualised arteriograms of the limbs can be obtained by xeroradiography after rapid manual injection of contrast-medium into an arm vein, as demonstrated in 28 patients. The technique is suitable for the diagnosis of circumscribed vascular lesions. It is simple to do and does not significantly distress the patient.
[Transvenous xerotom-angiography of the pulmonary hilus (author's transl)].
Normal-size lymph-nodes and air-filled bronchi do not contribute significantly to the shadow of the normal hilus. This consists mainly in pulmonary arteries and veins of the upper lobes. Any enlargement beyond the vascular shadow has to be considered as pathologic. Xerotom-angiography following injection of contrast medium into the cubital vein shows the pulmonary vessels near the hilus more clearly. Pulmonary arteries towards the truncus are better shown. This improves the clarity of the hilus. Coincident demonstration of the superior vena cava may show pathologic processes in the upper mediastinum.
