基于MRI的脑肿瘤计算机辅助检测技术研究进展

目的：总结计算机辅助检测技术在脑肿瘤检测领域的发展现状。方法：本文按照计算机辅助检测过程中的关键技术为分类，分别对其进行深入研究。结果：相对于其他肿瘤，脑肿瘤对患者的生存质量和生存时间的影响尤其严重。如果能在早期发现脑肿瘤并及时治疗，则可明显改善患者的生存质量，有效延长患者的生存时间。目前，磁共振成像（MRI）是显示脑肿瘤的最佳方式，但通过放射科医生对海量MRI图像进行判读发现早期脑肿瘤是非常困难的，而以图像处理与分析为基础的计算机辅助诊断（CAD）技术则是解决这一难题的有效途径。结论：本文对近年来基于MRI的脑肿瘤计算机辅助诊断技术的报道进行分析和深入研究，论述了脑肿瘤CAD的研究进展情况、存在的问题及可能的解决方案。

Progress in Computer-Aided Detection for Brain Tumor Using MRI

Objective： Make a summary of the development to the computer-aided detection technology in the field of brain tu- mor detection. Methods： This paper make a deep study in computer-aided detection according to the classification of the key technology. Results： Comparing with malignant tumors of other sorts, brain tumors especially has serious effect on living quali- ty and survival time of the patients. If detected earlier and treated in time, the patients＇ living quality can be apparently im- proved and their survival time can be prolonged efficiently. At present, the MRI is seen as the best approach to display brain tu- mors, but it is very difficult for radiologist to judge and distinguish early brain tumors from vast MRI images and the comput- er-aided diagnosis （CAD） technique based on image processing and analysis is an effective way to solve this problem. Conclu- sions： This paper analyzed the recent reports and literatures about the CAD for brain tumors with a deep research, the research progress about the CAD, the existed problems and the possible resolutions were discussed.
