In vivo validation of intravascular ultrasound length measurements using a motorized transducer pullback system

Am J Cardiol. 1996 May 15;77(12):1115-8. doi: 10.1016/s0002-9149(96)00145-2.


Using sonoreflective endovascular targets of known length (stainless steel tubular slotted stents), we have validated in vivo the accuracy and reproducibility of intravascular ultrasound length measurements using a system incorporating motorized transducer pullback through a stationary imaging sheath. The correlation was r = 0.936, with a measurement error of only +/- 5.2%, minimal intraobserver variability, and variability of sequential measurements of only +/- 4.8%.
