Iron deficiency anemia (IDA) and β-thalassemia trait (β-TT) are the most common types of microcytic hypochromic anemias. The similarity and the nature of anemia-related symptoms pose a foremost challenge for discriminating between IDA and β-TT. Currently, advances in technology have gave rise to computer-based decision-making systems. Therefore, advances in artificial intelligence have led to the emergence of intelligent systems and the development of tools that can assist physicians in the diagnosis and decision-making.
The aim of the present study was to develop a neural network based model (Artificial Neural Network) for accurate and timely manner of differential diagnosis of IDA and β-TT in comparison with traditional methods.
In this study, an artificial neural network (ANN) model as the first precise intelligent method was developed for differential diagnosis of IDA and β-TT. Data set was retrieved from Complete Blood Count (CBC) test factors of 268 individuals referred to Padad private clinical laboratory at Ahvaz, Iran in 2018. ANN models with different topologies were developed and CBC indices were examined for diagnosis of IDA and β-TT. The proposed model was simulated using MATLAB software package version 2018. The results showed the best network architecture based on the advanced multilayer algorithm (4 input factors, 70 neurons with acceptable sensitivity, specificity, and accuracy). Finally, the results obtained from ANN diagnostic model was compared to existing discriminating indexes.
The results of this model showed that the specificity, sensitivity, and accuracy of the proposed diagnostic system were 92.33%, 93.13%, and 92.5%, respectably; i.e. the model could diagnose frequent occurrence of IDA in patients with β-TT.
The results and evaluation of the developed model showed that the proposed neural network model has a proper accuracy and generalizability based on the initial factors of CBC testing compared to existing methods. This model can replace the high-cost methods and discriminating indices to distinguish IDA from β-TT and assist in accurate and timely manner diagnosis.
缺铁性贫血(IDA)和β地中海贫血特征(β-TT)是最常见的小细胞低色素性贫血类型。贫血相关症状的相似性及其本质对鉴别IDA和β-TT构成了首要挑战。目前,技术进步催生了基于计算机的决策系统。因此,人工智能的发展导致了智能系统的出现以及能够协助医生进行诊断和决策的工具的开发。
本研究的目的是开发一种基于神经网络的模型(人工神经网络),以便与传统方法相比,准确、及时地鉴别诊断IDA和β-TT。
在本研究中,开发了一种人工神经网络(ANN)模型作为第一种精确的智能方法,用于鉴别诊断IDA和β-TT。数据集取自2018年转诊至伊朗阿瓦士帕达德私人临床实验室的268名个体的全血细胞计数(CBC)检测因子。开发了具有不同拓扑结构的ANN模型,并检查CBC指标以诊断IDA和β-TT。使用MATLAB软件包版本2018对所提出的模型进行模拟。结果显示基于先进多层算法的最佳网络架构(4个输入因子,70个神经元,具有可接受的敏感性、特异性和准确性)。最后,将ANN诊断模型获得的结果与现有的鉴别指标进行比较。
该模型的结果表明,所提出的诊断系统的特异性、敏感性和准确性分别为92.33%、93.13%和92.5%;即该模型可以诊断β-TT患者中IDA的频繁发生情况。
所开发模型的结果和评估表明,与现有方法相比,所提出的神经网络模型基于CBC检测的初始因子具有适当的准确性和通用性。该模型可以替代高成本方法和鉴别指标来区分IDA和β-TT,并有助于准确、及时地进行诊断。
