    Will the Combination of US Contrast Microbubbles and High-Intensity Focused Ultrasound Enable Noninvasive Brain Surgery?

    Radiology October 2006 241:1-2; doi:10.1148/radiol.2411060904

    McDannold et al have demonstrated that the administration of a microbubble-based US contrast agent reduces the acoustic power threshold required to induce lesions in rabbit brains with high-intensity focused ultrasound and that this procedure may potentially be monitored with MR thermometry.

    Prevalence and Clinical Importance of Aortic Valve Calcification Detected Incidentally on CT Scans: Comparison with Echocardiography

    Radiology October 2006 241:76-82; Published online August 14, 2006, doi:10.1148/radiol.2411051163

    Because there is a significant correlation between the grade of aortic valve calcification and the echocardiographically determined hemodynamic severity of calcific aortic valve disease, patients with grade 3 or 4 aortic valve calcification at multi–detector row CT may require further functional assessment with echocardiography.

    In patients with clinically manifest Budd-Chiari syndrome who were treated with expanded polytetrafluoroethylene-covered Viatorr stent-grafts compared with patients who were treated with Wallstents, there was a significant increase in the primary patency rate (100% and 85.7% vs 16.7% and 0% at 6 and 12 months, respectively; P < .001), a decrease in the reintervention rate (0.29 ± 0.49 vs 6.17 ± 1.72, P < .001), and a more persistent and significantly greater improvement in hepatic function.
