OBJECTIVE: We aimed to propose an automatic method based on Support Vector
Machine (SVM) and Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI)
to segment the tumor lesions of head and neck cancer (HNC). MATERIALS AND
METHODS: 120 DCE-MRI samples were collected. Five curve features and two
principal components of the normalized time-intensity curve (TIC) in 80 samples
were calculated as the dataset in training three SVM classifiers. The other 40
samples were used as the testing dataset. The area overlap measure (AOM) and the
corresponding ratio (CR) and percent match (PM) were calculated to evaluate the
segmentation performance. The training and testing procedure was repeated for 10
times, and the average performance was calculated and compared with similar
studies. RESULTS: Our method has achieved higher accuracy compared to the
previous results in literature in HNC segmentation. The average AOM with the
testing dataset was 0.76 ± 0.08, and the mean CR and PM were 79 ± 9% and 86 ± 8%,
respectively. CONCLUSION: With improved segmentation performance, our proposed
method is of potential in clinical practice for HNC.
