These seasoned investigators sought to evaluate the efficacy and safety of flow-diverting devices for the treatment of complex paraclinoid aneurysms in 21 patients and compared their results with historical matched controls treated at their institution. Aneurysm size, location, risk factors, and comorbidities were equal for both groups. In the hands of these authors, flow diverters achieved a higher rate of aneurysm obliteration when compared with other treatments and did not show an increased rate of complications.

In this study the feasibility of using dynamic postcontrast imaging to separate hypo- and hypervascular spine metastases was assessed. Using a T1 postcontrast sequence with temporal resolution of 6 seconds, the authors imaged spine lesions in 26 patients and from the data collected calculated 3 dynamic parameters. Hypervascular lesions showed steeper and higher wash-in slopes and higher peak enhancement. Conversely, conventional pre- and postcontrast images were unable to differentiate lesions.
