背景:窄带成像(NBI)可以改善对呼吸消化道病变的检测。然而,其在喉良性病变中的作用尚不清楚。这项研究旨在确定NBI是否改善了疤痕的检测,沟,和结节与使用客观图像分析的全色照明相比。
方法:总共,在有或没有NBI的情况下分析了120个声带(21个正常,15个疤痕,16沟,和45个结节)。每个VF图像都有前,中间,使用面积形态测量软件(Optimas5.1a)分析后三分之二的亮度。对于绝对灰度的平均值和标准偏差(SD),针对周围的VF区段分析具有损伤的中间三分之一。
结果:与NBI相比,使用全色光会产生更大的照度和灰度值。所有病变都倾向于中膜性褶皱。在全色光下,比较前与中(A-M)时,亮度变化为+6.1%,与6.5%相比,8.1%,而沟为7.1%,结节,和疤痕,分别。在NBI下,它们是9.0%(正常),12.3%(沟),13.7%(结节),和13.1%(疤痕)。当使用NBI时,在病理部位观察到更大的发光SD(p<0.05)。使用NBI时,所有病变部位的绝对灰度变化均大于使用全色光时(p<0.05)。
结论:NBI显著增强结节患者的病理面积,沟,和疤痕。与正常部位相比,病理部位的灰度SD值较高。因此,与全色光相比,NBI可以改善对音波损伤的检测。

BACKGROUND: Narrow-band imaging (NBI) can improve detection of lesions in the aerodigestive tract. However, its role in benign lesions of the larynx is unclear. This study aims to determine whether NBI improves the detection of scars, sulci, and nodules compared to panchromatic lighting using objective image analysis.
METHODS: In total, 120 vocal folds (VFs) were analyzed with and without NBI (21 normal, 15 scars, 16 sulci, and 45 nodules). Each VF image had anterior, middle, and posterior thirds analyzed for brightness using an area morphometry software (Optimas 5.1a). The middle-third with the lesion was analyzed against surrounding VF segments for average and standard deviation (SD) in absolute grayscale.
RESULTS: The use of panchromatic light resulted in greater illumination and grayscale values than NBI. All lesions tended to be in the mid-membranous fold. Under panchromatic light, change in brightness when comparing anterior versus middle (A-M) was +6.1% for normal, versus 6.5%, 8.1%, and 7.1% for sulci, nodules, and scars, respectively. Under NBI, they were 9.0% (normal), 12.3% (sulci), 13.7% (nodules), and 13.1% (scars). A greater SD of luminescence was observed at pathology sites (p < 0.05) when using NBI. The change in absolute grayscale at all lesion sites was greater when using NBI than when using panchromatic light (p < 0.05).
CONCLUSIONS: NBI significantly enhanced the area of pathology in patients with nodules, sulci, and scars. Greater SD values in grayscale at pathologic sites were observed compared at normal sites. Thus, NBI may improve the detection of phonotraumatic lesions compared to panchromatic light.
