Abstract

Low back pain (LBP) is one of the most common diseases affecting a large number of people. Diagnosis and treatment of LBP require quick, accurate imaging methods. Magnetic resonance imaging (MRI) is effective in distinguishing between vertebra, intervertebral disc and spinal cord, and thus is used frequently in spinal cord injury (SCI) diagnosis. This paper proposes a fully automated approach to detecting region of interest (ROI) using T2-weighted MRI images. Our dataset included the cases of 100 patients who suffered from LBP. In total, 2000 axial and 1200 sagittal ROI were marked in the Lumbar spine. Extracted ROIs were used in the cascade classifier learner. In this method, ROI detection consists of two processes. First the ROIs are specified using the cascade classifier, and then via a process, non-regions of interest (NROIs) are discarded. Histogram of Oriented Gradient (HOG) was used as the feature descriptor in each stage of the Cascade classifier. This method does not require background knowledge of input images and it is reliable regardless of the images size, contrast and clinical abnormally of cases. The quantitative and qualitative evaluation results of the proposed ROI detector were 83% and above 94%, respectively.
腰椎MRI自动ROI检测
腰痛(LBP)是影响大量人群的最常见疾病之一。腰痛的诊断和治疗需要快速、准确的影像学方法。磁共振成像(MRI)能有效地区分椎体、椎间盘和脊髓,因此在脊髓损伤(SCI)诊断中得到了广泛的应用。本文提出了一种利用t2加权MRI图像检测感兴趣区域(ROI)的全自动方法。我们的数据集包括100例患有LBP的患者。腰椎总共有2000个轴位和1200个矢状位ROI。将提取的roi用于级联分类器学习。在该方法中,ROI检测包括两个过程。首先使用级联分类器指定roi,然后通过一个过程,丢弃非感兴趣区域(nroi)。梯度直方图(Histogram of Oriented Gradient, HOG)作为分级器各阶段的特征描述符。该方法不需要输入图像的背景知识,无论图像大小、对比度和病例的临床异常情况如何,该方法都是可靠的。所提出的ROI检测器的定量和定性评价结果分别为83%和94%以上。
