Time-of-Arrival Mapping at Three-dimensional Time-resolved Contrast-enhanced MR Angiography [Technical Developments]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study was HIPAA compliant and institutional review board approved, and informed consent was obtained from all volunteers. The authors describe a method for generating a time-of-arrival (TOA) map of intravenously administered contrast material, as observed in a time series of three-dimensional (3D) contrast material–enhanced magnetic resonance (MR) angiograms. The method may enable visualization and interpretation, on one 3D image, of the temporal enhancement patterns that occur in the vasculature. Colorization of TOA values may further aid interpretation. The quality of the results depends not only on the adequa...

Wide-necked Intracranial Aneurysms: Treatment with Stent-assisted Coil Embolization during Acute (Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Stent-assisted coil embolization is a feasible method for the endovascular treatment of wide-necked intracranial aneurysms that are difficult to treat surgically or with balloon-assisted embolization during acute SAH. The risk of subsequent rerupture of the aneurysm seems to be reduced for aneurysms treated early compared with that for nonsecured aneurysms. © RSNA, 2009 (Source: Continuous Publishing articles)

In Vitro Labeling of Mesenchymal Stem Cells with Superparamagnetic Iron Oxide by Means of Microbubble-enhanced US Exposure: Initial Experience [Molecular Imaging]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Initial study results show that stem cells can be effectively labeled with SPIO by using MUE without secondary transfection agents and thus that MUE labeling is an appealing alternative cell-labeling approach that warrants investigation for intracellular magnetic labeling of stem cells.

Right Hepatic Vein Stenosis at Anastomosis in Patients after Living Donor Liver Transplantation: Optimal Doppler US Venous Pulsatility Index and CT Criteria--Receiver Operating Characteristic Analysis [Ultrasonography]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: CT is more accurate than Doppler US for RHV stenosis after LDLT, with venous pulsatility index as the sole sonographic criterion. Patients suspected of having RHV stenosis at Doppler US may benefit from CT to reduce unnecessary venography. © RSNA, 2009 (Source: Continuous Publishing articles)

Cystic Fibrosis: Are Volumetric Ultra-Low-Dose Expiratory CT Scans Sufficient for Monitoring Related Lung Disease? [Pediatric Imaging]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: In this pilot study, CT scores from end-expiratory and end-inspiratory CT match closely, suggesting that ultra-low-dose end-expiratory CT alone may be sufficient for monitoring CF-related lung disease. This would help reduce radiation dose for a single investigation by up to 75%. © RSNA, 2009 (Source: Continuous Publishing articles)
