Precise measurement of luminal diameter in arteries is important when planning interventional vascular procedures in patients. Measuring wall volume may be important in detecting early artery disease and in the assessment of treatments to prevent atherosclerosis. An ex vivo phantom using porcine arteries was used to evaluate the accuracy with which (i) B-mode ultrasound, (ii) 3-D tomographic ultrasound (tUS), (iii) computed tomography (CT) and (iv) magnetic resonance imaging (MRI) measured length, diameters and volume. The mean error in inner-to-inner diameter measurements by B mode, tUS, CT and MRI were 0.08 ± 0.26, -0.73 ± 0.96 mm, 0.09 ± 0.55 and 0.60 ± 1.01 mm, respectively. The mean error in outer-to-outer diameter measurements by B mode, tUS, CT and MRI were -1.33 ± 0.61, -1.03 ± 0.35, 0.02 ± 1.00 and -0.47 ± 1.32 mm, respectively. The mean error in volume measurements by B mode, tUS, CT and MRI were -0.54 ± 0.62, -0.06 ± 0.09, 0.01 ± 0.18 and -0.20 ± 0.32 cm, respectively. Errors in length and diameters remain within clinically acceptable thresholds where MRI was the least accurate. tUS was the most accurate method of volume measurement.
在计划患者的介入血管程序时，精确测量动脉管腔直径非常重要。测量管壁体积可能对于早期检测动脉疾病以及评估预防动脉粥样硬化的治疗方法非常重要。使用猪动脉的离体体模评估了 (i) B 型超声、(ii) 3-D 断层超声 (tUS)、(iii) 计算机断层扫描 (CT) 和 (iv) 磁共振成像 (MRI) 测量长度、直径和体积的准确性。B 型、tUS、CT 和 MRI 对内径测量的平均误差分别为 0.08 ± 0.26、-0.73 ± 0.96、0.09 ± 0.55 和 0.60 ± 1.01mm。B 型、tUS、CT 和 MRI 对外径测量的平均误差分别为-1.33 ± 0.61、-1.03 ± 0.35、0.02 ± 1.00 和-0.47 ± 1.32mm。B 型、tUS、CT 和 MRI 体积测量的平均误差分别为-0.54 ± 0.62、-0.06 ± 0.09、0.01 ± 0.18 和-0.20 ± 0.32cm。MRI 测量的长度和直径误差仍然在临床可接受的范围内，而 MRI 的准确性最低。tUS 是体积测量最准确的方法。
