Diagnostic imaging of and radiologic intervention for bovine ureter grafts used as a novel conduit for hemodialysis fistulas.

Objective: The objectives of our study were to review the appearances on diagnostic imaging and amenability to imaging-guided intervention of a novel bovine ureter graft (Syner-Graft 100 [SG 100]) for use as a conduit for hemodialysis fistulas.

Conclusion: The SG 100 shows initial promise as a conduit for hemodialysis fistulas in patients with difficult vascular access. The SG 100 has characteristic appearances on diagnostic imaging and is prone to similar pathologic processes that affect autogenous venous and synthetic grafts.

Cerebral perfusion abnormalities in children with Sturge-Weber syndrome shown by dynamic contrast bolus magnetic resonance perfusion imaging.

Objective: Sturge-Weber syndrome is characterized by leptomeningeal angiomatosis and a facial naevus that is usually unilateral. Magnetic resonance imaging is the cornerstone of confirming the disease and judging the extent of the abnormalities. It has been shown, however, that brain perfusion abnormalities on nuclear medicine imaging often are more extensive than the abnormal leptomeningeal enhancement on magnetic resonance.

Ruptured fusiform aneurysm of fenestrated A1 segment of the anterior cerebral artery. Case report and review of the literature.

We present a case report of a 56-year-old woman with a ruptured fusiform aneurysm of a fenestrated A(1) segment of the anterior cerebral artery (ACA). Fenestrated A(1) segments are rare and only a few case reports have been published of a saccular type aneurysm formation. To the best of our knowledge, there have been no documented cases of fusiform aneurysms in these segments.

Radiology in pleural disease: state of the art.

Diseases of the pleura and pleural space are common and present a significant contribution to the workload of the chest radiologist. The radiology department plays a crucial role in the imaging and management of pleural disease. This review aims to describe and illustrate the appearances of common pleural pathologies on various radiological modalities including plain film, ultrasound, CT, magnetic resonance imaging and positron emission tomography.
