To determine the utility of tissue harmonic imaging in evaluating cystic renal lesions and to compare these findings with conventional ultrasound guidance (USG) and CT.
Thirty patients, detected with cystic renal lesions on routine USG (over a period of 18 months from July 2004 to December 2005 at the Postgraduate Institute of Medical Education and Research Chandigarh, Chandigarh, India) were included in this study. All patients underwent a conventional gray scale ultrasound study (GSI), followed by tissue harmonic imaging (THI) sonography on the same machine (advance technology limited high definition imaging 5000). Computed tomography of abdomen was carried out within one week of the ultrasound examinations. All images were evaluated for size, number, and location of lesions. The findings of THI sonography, conventional USG and CT of abdomen were recorded in their respective proformas. The images obtained by GSI, THI, and contrast enhanced CT were also evaluated for image quality, lesion conspicuity, and fluid-solid differentiation.
Tissue harmonic imaging showed better image quality in 27 of 34 lesions, improvement in lesion conspicuity was found in 27 of 34 cystic lesions, and an improved solid-fluid differentiation in 30 of 34 lesions when compared to GSI. The THI provided additional information as compared to GSI in 8 patients. The grading of CT scan was significantly higher in overall image quality (p=0.007) and lesion conspicuity (p=0.004), but was non-significant for fluid-solid differentiation (p=0.23).
Tissue harmonic imaging provides better image quality, lesion delineation, and superior characterization than conventional gray scale sonography.
确定组织谐波成像在评估肾囊性病变中的效用，并将这些结果与传统超声引导（USG）和CT进行比较。
本研究纳入了30例在常规USG检查中发现肾囊性病变的患者（2004年7月至2005年12月期间，于印度昌迪加尔医学教育与研究研究生院，共18个月）。所有患者均在同一台机器（先进技术有限公司高清成像5000）上进行了常规灰阶超声检查（GSI），随后进行了组织谐波成像（THI）超声检查。在超声检查后一周内进行腹部计算机断层扫描。评估所有图像中病变的大小、数量和位置。将THI超声检查、传统USG和腹部CT的结果记录在各自的表格中。还对通过GSI、THI和对比增强CT获得的图像进行了图像质量、病变清晰度和液-固鉴别评估。
与GSI相比，组织谐波成像在34个病变中的27个显示出更好的图像质量，在34个囊性病变中的27个发现病变清晰度有所提高，在34个病变中的30个实现了更好的液-固鉴别。与GSI相比，THI在8例患者中提供了额外信息。CT扫描在整体图像质量（p=0.007）和病变清晰度（p=0.004）方面的分级显著更高，但在液-固鉴别方面无显著差异（p=0.23）。
与传统灰阶超声相比，组织谐波成像提供了更好的图像质量、病变描绘和更优的特征表现。
