摘要
背景:结肠直肠癌是世界上最重要的癌症类型之一,通常会导致死亡,因此计算机辅助诊断(CAD)系统是早期诊断这种疾病的一个很有前途的解决方案,与传统的结肠镜检查相比,它的副作用更小。因此,本研究的目的是结合人工神经网络和粒子群优化器,设计一种处理结肠直肠计算机断层扫描(CT)图像的计算机辅助诊断系统:首先,研究数据集来自德黑兰 Loghman-e Hakim 医院和伊斯法罕 Al-Zahra 医院的结肠直肠 CT 图像,这些患者接受了结肠直肠 CT 成像检查,并在检查后最长一个月内进行了常规结肠镜检查。随后进行了模型实施步骤,包括图像的电子清洗、分割、样本标记、特征提取,以及使用粒子群优化器对人工神经网络(ANN)进行训练和优化。使用二项式统计检验和混淆矩阵计算对模型进行评估:经 McNemar 检验,在 P 值 = 0.000 的情况下,模型的准确度、灵敏度和特异度分别为 0.9354、0.9298 和 0.9889。此外,模型与 Loqman Hakim 医院和 Al-Zahra 医院放射科医生诊断比率的二项检验 P 值分别为 0.044 和 0.021:统计检验和研究变量的结果表明,在从 CTC 图像诊断结直肠息肉方面,与放射科医生的意见相比,基于 ANN 和粒子群优化混合法创建的 CTC-CAD 系统具有很高的效率。
Designing a Hybrid Method of Artificial Neural Network and Particle Swarm Optimization to Diagnosis Polyps from Colorectal CT Images.
Background: Since colorectal cancer is one of the most important types of cancer in the world that often leads to death, computer-aided diagnostic (CAD) systems are a promising solution for early diagnosis of this disease with fewer side effects than conventional colonoscopy. Therefore, the aim of this research is to design a CAD system for processing colorectal Computerized Tomography (CT) images using a combination of an artificial neural network and a particle swarm optimizer.
Method: First, the data set of the research was created from the colorectal CT images of the patients of Loghman-e Hakim Hospitals in Tehran and Al-Zahra Hospitals in Isfahan who underwent colorectal CT imaging and had conventional colonoscopy done within a maximum period of one month after that. Then the steps of model implementation, including electronic cleansing of images, segmentation, labeling of samples, extraction of features, and training and optimization of the artificial neural network (ANN) with a particle swarm optimizer, were performed. A binomial statistical test and confusion matrix calculation were used to evaluate the model.
Results: The values of accuracy, sensitivity, and specificity of the model with a P value = 0.000 as a result of the McNemar test were 0.9354, 0.9298, and 0.9889, respectively. Also, the result of the P value of the binomial test of the ratio of diagnosis of the model and the radiologist from Loqman Hakim and Al-Zahra Hospitals was 0.044 and 0.021, respectively.
Conclusions: The results of statistical tests and research variables show the efficiency of the CTC-CAD system created based on the hybrid of the ANN and particle swarm optimization compared to the opinion of radiologists in diagnosing colorectal polyps from CTC images.
