“…The sensitivity of IVUS for documenting dissection was good (74%), but was low for media rupture (59%). Similar sensitivities for dissection have been reported by others [11,17,18]. However, in the present study both incidence (28%) and sensitivity of media rupture (59%) seen with IVUS were lower than reported in coronary arteries studied in vitro (43% and 76%, respectively) [11].…”

“…Recently, three-dimensional (3-D) image reconstruction and analysis systems have been introduced [3,4,[6][7][8][9][10][11][12][13][14], which can be used for quantitative analyses of ICUS image data. Such 3-D systems generally acquire sequences of ICUS images during uniform-speed motorized pullbacks.…”

The quantitative analysis of a three‐dimensional (3‐D) intracoronary ultrasound (ICUS) image data set permits a more comprehensive assessment of coronary arterial segments. The 3‐D image sets are generally acquired during continuous motorized pullbacks. However, the cyclic changes of vascular dimensions and the cyclic spatial displacement of the ICUS transducer relative to the vessel wall can result in characteristic image artifacts, which may limit the applicability of quantitative automated analysis systems. This limitation may be overcome by an ECG‐gated image acquisition. In the present study we acquired in vivo (1) nongated and (2) ECG‐gated 3‐D ICUS image sets of 15 human atherosclerotic coronary arteries and performed a computer‐assisted contour detection of the lumen and total vessel boundaries. Total vessel and lumen volumes measured significantly larger in the nongated versus ECG‐gated end‐diastolic image sets (753 ± 307 mm3 vs. 705 ± 305 mm3; 411 ± 154 mm3 vs. 388 ± 165 mm3, both: P < 0.05). Both end‐diastolic and systolic measurements were available in nine arteries, showing a larger total vessel and lumen volume at systole (664 ± 221 mm3 vs. 686 ± 227 mm3, P = 0.03; 384 ± 164 mm3 vs. 393 ± 170 mm3, P = 0.08). The differences observed may be of particular interest for volumetric ICUS studies, addressing presumably small differences in vessel or lumen dimensions. Cathet. Cardiovasc.

“…In radiology, the combination has been introduced and has shown its value, due to the fact that systematic sampling can be achieved using CT and MRI scans [14][15][16]34]. Also in vascular biology, the intravascular ultrasound technique could show 3-D reconstruction of the intima from 2-D images facilitating the interpretation of morphological changes after balloon angioplasty [17,18]. Recently, a novel morphometrical system was developed to analyse 3-D IVUS images which also applies systematic sampling [35].…”

“…This technique has been used successfully both in pathology and in clinical CT and MRI imaging [14][15][16]. Intravascular ultrasound (IVUS) images could also give 3-D information on intimal thickening and remodelling of the artery after balloon angioplasty [17,18]. However, this technique often uses planimetry to quantify the relevant parameters.…”

Semi-automatic computer-assisted planimetry is often used for the quantification of restenosis parameters after balloon angioplasty although it is a time-consuming method. Moreover, slicing the artery to enable analysis of two-dimensional (2-D) images leads to a loss of information since the vessel structure is three-dimensional (3-D). Cavalieri’s principle uses systematic random sampling allowing 3-D quantification. This study compares the accuracy and efficiency of planimetry versus point-counting measurements on restenosis parameters after balloon angioplasty and investigates the use of Cavalieri’s principle for 3-D volume quantification. Bland and Altman plots showed good agreement between planimetry and point counting for the 2-D and 3-D quantification of lumen, internal elastic lamina (IEL) and external elastic lamina (EEL), with a slightly smaller agreement for intima and media. Mean values and induced coefficients of variation were similar for both methods for all parameters. Point counting induced a 6% error in its 3-D quantification, which is negligible in view of the biological variation (>90%) among animals. However, point counting was 3 times faster compared to planimetry, improving its efficiency. This study shows that combining Cavalieri’s principle with point counting is a precise and efficient method for the 3-D quantification of restenosis parameters after balloon angioplasty.
