摘要

为了评估基于导管的超声成像的潜在图像质量及其对诊断和治疗应用的意义，作者对尸体解剖获得的人肾动脉、髂动脉和股动脉进行了体外成像。超声成像采用20- mhz和30-MHz聚焦圆盘换能器，活动孔径分别为2mm和1mm。从2-T，高分辨率磁共振成像仪(MRI)的相关图像，以及标本显微照片也被拍摄。初步结果表明，常规超声成像可达到诊断质量，导管超声成像可作为血管成形术和手术的有效辅助手段。

Feasibility and diagnostic value of catheter-based ultrasonic systems for intravascular imaging: in vitro comparisons with MRI

In order to assess the potential image quality of catheter-based ultrasonic imaging and its implications for diagnostic as well as therapeutic use, the authors imaged, in vitro, human renal, iliac, and femoral arteries obtained from autopsy. Ultrasonic imaging was performed using 20- and 30-MHz focused disk transducers of 2-mm and 1-mm-diameter active apertures, respectively. Correlative images from a 2-T, high-resolution magnetic resonance imager (MRI), as well as specimen photomicrographs were also taken. Preliminary results suggest that images of diagnostic quality can be routinely obtained, and catheter-based ultrasonic imaging can serve as an effective adjunct to vascular angioplasty and surgery.<>
