| pubmed-article:2781021 | pubmed:abstractText | The right anterior caudocranial oblique (RACCO) view is proposed for improved depiction of the portal venous system. It is achieved by tilting the image intensifier 25 degrees caudal and 25 degrees-30 degrees to the right and maintaining the patient in the supine position. Transarterial portography with digital subtraction angiography was performed in the RACCO and posteroanterior (PA) views in 22 patients. Comparison of the two views revealed that the RACCO view was superior to the PA view of the left main branch in 15 patients (68%) and of the right posterior lobe branch in 19 patients (86%). The RACCO view will be useful for the evaluation of the portal system in patients with primary and secondary hepatic neoplasms in whom detailed images are important for diagnosis treatment planning. | lld:pubmed |
