目的讨论二维超声结合彩色多普勒闪烁伪像在对于结核性胸膜炎的诊断价值。方法对2014年1—10月期间102例临床诊为结核性胸膜炎的患者进行常规二维超声检查,全部应用频谱多普勒及彩色多普勒扫查,观察二维超声上胸膜增厚的形态,评价二维超声、彩色多普勒闪烁伪像及常规CT平扫对于胸膜钙化灶的检出有无差异,计数资料采用χ2检验,P<0.05为差异有统计学意义。结果 102例结核性胸膜炎患者中,69例普通二维超声显示胸膜增厚,46例伴有钙化,并出现闪烁伪像,28例二维超声显示胸腔积液内有中等回声或中等偏强回声,但仍出现闪烁伪像;其余5例二维超声显示胸腔积液无闪烁伪像。二维超声共检出胸膜钙化20例(19.6%),CT共检出钙化30例(29.4%),二维超声联合多普勒闪烁伪像共检出钙化48例(47.1%)。对于钙化灶的检出,二维超声联合彩色多普勒闪烁伪像显著优于CT平扫,差异有统计学意义(P<0.05)。CT平扫优于二维超声,差异无统计学意义(P>0.05)。结论二维超声联合彩色多普勒闪烁伪像可以更好地显示胸膜病变的内部特征,并可显著提高胸膜钙化的检出,对于结核性胸膜炎的诊断有一定的临床意义。
Objective To discuss the diagnostic value of two-dimensional ultrasound combined with color Doppler flickering artifact in the diagnosis of tuberculous pleurisy. Methods Totally 102 cases of tuberculous pleurisy patients were diagnosed by routine two-dimensional ultrasonography during January-October 2014. All cases were examined by spectral Doppler and color Doppler imaging to observe the morphology of pleural thickening on two-dimensional ultrasound , Evaluate the two-dimensional ultrasound, color Doppler flicker artifact and conventional CT scan pleural calcification for the presence or absence of any difference, count data using χ2 test, P <0.05 for the difference was statistically significant. Results Of the 102 patients with tuberculous pleurisy, 69 cases of general two-dimensional ultrasound showed pleural thickening, 46 cases with calcification, and flickering artifacts, 28 cases of two-dimensional ultrasound showed pleural effusion with moderate echo or moderate partial echo , But still flickering artifact; the remaining five cases of two-dimensional ultrasound showed no flicker artifact pleural effusion. Pleural calcification was detected in 20 cases (19.6%) by two-dimensional ultrasonography. CT was detected in 30 cases (29.4%), calcification in 48 cases (47.1%) by two-dimensional ultrasound combined with Doppler flicker artifact. For the detection of calcification, two-dimensional ultrasound combined with color Doppler flickering artifact was significantly better than CT scan, the difference was statistically significant (P <0.05). CT scan better than two-dimensional ultrasound, the difference was not statistically significant (P> 0.05). Conclusion Two-dimensional ultrasound combined with color Doppler flickering artifact can better display the internal characteristics of pleural disease, and can significantly increase the detection of pleural calcification, for the diagnosis of tuberculous pleurisy has some clinical significance.
