The Reproducibility of Intravascular Ultrasound Imaging In Vitro

IVUS analysis of the acute and long-term stent result using motorized pullback: Intraobserver and interobserver variability

“…Absolute and relative differences between repetitive measurements were low and comparable to those reported for still frames in peripheral arteries [12]. Measurements showed no significant bias and good correlation, similar to data for in vitro studies [13]. They were similar immediately and late after stent implantation and comparable to previously reported data for acute stent implantation by Kearny et al [9].…”

Original studies: Comparison of angiography and intravascular ultrasound for the assessment of lumen size after coronary stent placement: Impact of dilation pressures

“…IVUS is a tomographical technique that enables cross-sectional imaging of the lumen area, lumen diameter, and vessel wall components [17,18]. Comparative investigations in healthy subjects displayed very good agreement for the two methods in the assessment of luminal diameters [19][20][21][22]. A similarly good correlation could be demonstrated in the detection and evaluation of concentric arteriosclerotic vessel alterations [23].…”

“…However, because of well-known limitations, coronary angiography as a silhouette technique cannot provide all of these prerequisites.15 In contrast, intravascular ultrasound (IVUS) is a high-resolution tomographic technique for valid quantifications of coronary artery diameters and cross-sectional areas even in irregular and eccentric lesions. [16][17][18][19] In addition, IVUS allows the assessment of dimensions and characteristic features of different components of the vessel wall.20'2' In the clinical setting, this method has been shown to be a safe diagnostic tool in conjunction with interventional procedures.22-24 However, in these indications, the transformation of the sonographic information into procedural consequences requires multiple exchanges between the interventional and IVUS device. This not only is time-consuming but could even be harmful immediately after stent delivery.…”
