Is there a universally accepted, among radiologists, technique for leg length on the CT scanners?
I can't find one, and our radiologist want me to develop one.
I have tried using the scanogram, and the scanner calipers, or measurment tool to measure, but I'm not sure how much distortion there is on the scanogram, and if the measurement is correct.

Thanks in advance,

CTDave

No, don't think so. I just asked some friends and had a look on the net, there's nothing about a universal technique. Sorry. This might have something on it though, but it's fairly narrow.

Jagg,
Thanks for the article on Intrinsic measurement bias on computed tomography scout view is unpredictable: Computed tomography pelvimetry using a phantom from Australasian Radiology Volume 50 Page 127 - April 2006 doi:10.1111/j.1440-1673.2006.01555.x Volume 50 Issue 2 and Blackwell Synergy.
Since we only do about 3 to 5 cases a year, I will present this article to the radiologist's, and let them decided. I will continue to use the method described in my original post.

Thanks again

CTDave Very Happy
