Brain tumors and difusion tensor imaging

Check out the latest concepts in delineation of spread of gliomas in the article : "Gliomas: Histopathologic Evaluation of Changes in Directionality and Magnitude of Water Diffusion at Diffusion-Tensor MR Imaging" by Andreas Stadlbauer et al in the latest edition of Radiology 2006;240 803-810, also available online at
http://radiology.rsnajnls.org/cgi/content/abstract/240/3/803?etoc

The article describes how fractional anisotropy is better than mean diffusivity for assessment and delineation of different degrees of pathologic changes (ie, tumor infiltration) in glioma.

Hepatic chemoembolizaton

read the latest on "Intraarterial Gene Delivery in Rabbit Hepatic Tumors: Transfection with Nonviral Vector by Using Iodized Oil Emulsion" byYoung Il Kim, et al in Radiology 2006;240 771-777 also available online at:
http://radiology.rsnajnls.org/cgi/content/abstract/240/3/771?etoc

The article describes how the authors developed DNA carrier complexes, by using iodized oil and iopamidol, that may be used as modifiers for intraarterial gene delivery. Absolutely cutting edge and exciting stuff. Full article can be accessed at IRIA HQ.

MR safety after coronary revascularization

Check out this article: "Acute Myocardial Infarction: Safety of Cardiac MR Imaging after Percutaneous Revascularization with Stents" by Manesh R. Patel, MD, et al ; reassuring as it tells us that MR imaging is safe in immediate post-stenting cases. read all about it in Radiology 2006;240 674-680 and access online at

Full copy of this article is available at IRIA HQ.
A must read dialogue between Dr. Ronai & Dr. Semelka on radiation risk form diagnostic X-rays and CT discusses whether a risk of 1 in 1000 of developing cancer after a CT scan is realistic or alarmist. Read all about it on http://www.medscape.com/viewarticle/542696?src=mp
The latest in the debate on radiation risk from MDCT, a radio-biologist gives his scientific analysis of the problem and virtually shrugs off the problem as causing insignificant risk of future cancer. Read all about it on http://www.medscape.com/viewarticle/543008?src=sr
The doomsayer strikes back. Dr. Semelka counters the criticism from his peers and advises caution in CT studies. Read about it on http://www.medscape.com/viewarticle/542555?src=sr
