Computer-aided Detection of Brain Metastases Using MR Images

Early diagnosis for brain metastases has been one challenge issue in cancer therapies.This paper presented a computer-aided detection method for brain metastases based on the 3D template matching.First step,build up an appropriate brain metastases template;and secondly,search for regions of interesting(ROI) that similar to the template,which are very likely to be the candidate brain metastases.12 datasets that have total 27 brain metastases(less than 8 mm) were used to examine the efficiency of the method.The experimental results showed that the sensitivity of the method was 81.5% and the false positive was about 0.453 8 for every slice.Therefore,the computer-aided detection method provides a solution for the early diagnosis of brain metastases.
