Musings in the life of an internist, cardiologist and cardiac electrophysiologist.
MSCT is turning into an arms race.We covered the radiation risks of 64MSCT herehttp://hmatter.blogspot.com/2008/01/radiation-hazards-of-64-msct.htmlThe accuracy of 64 MSCT herehttp://hmatter.blogspot.com/2008/06/at-clinic-accuracy-of-64-msct.htmlAnd an update herehttp://hmatter.blogspot.com/2008/11/latest-on-64msct-core64.html
At journal club the other day we discussed a recent NAC study regarding contast induced nephropathy. One of the attendings mentioned that VENOUS administration of contrast was more likely to induce CIN than was aterial use of contrast. I had not heard that before. Might be a significant consideration when deciding re: CTA. Personally I do not see a need to use for CAD, and basically think it should be used it for planning for ablation, or anomalous cor arteries or hx of CABG w/ LIMA and need to define LIMA location prior to repeat sternotomy.
