Key result
Three-dimensional ultrasound measurement of plaque volume using manual planimetry demonstrated a mean accuracy of 3.1+/-0.9% and intraobserver variability of 4.0+/-1.0% in vascular phantoms.
Why the study?
Does three-dimensional ultrasound accurately and reliably measure carotid plaque volume in test phantoms compared to water displacement?
Does three-dimensional ultrasound accurately and reliably measure carotid plaque volume in test phantoms compared to water displacement?
Three-dimensional ultrasound using serial 2D manual planimetry provides highly accurate and reproducible measurements of carotid plaque volume in phantom models.

Phantom validation supports method refinement; leaves open clinical translation to carotid plaque volumetry.
Landry et al. (2002) studied Carotid plaque volume measurement (phantom study). Three-dimensional ultrasound with manual planimetry vs. Water displacement (true volume) was evaluated on Accuracy and variability of plaque volume measurement. Three-dimensional ultrasound measurement of plaque volume using manual planimetry demonstrated a mean accuracy of 3.1+/-0.9% and intraobserver variability of 4.0+/-1.0% in vascular phantoms.
