Deep vein thrombosis (DVT) is a disease caused by abnormal blood clots in deep veins. Accurate segmentation of DVT is important to facilitate the diagnosis and treatment. In the current study, we proposed a fully automatic method of DVT delineation based on deep learning (DL) and contrast enhanced magnetic resonance imaging (CE-MRI) images.<jats:italic> Methods<\/jats:italic>. 58 patients (25 males; 28~96 years old) with newly diagnosed lower extremity DVT were recruited. CE-MRI was acquired on a 1.5 T system. The ground truth (GT) of DVT lesions was manually contoured. A DL network with an encoder-decoder architecture was designed for DVT segmentation. 8-Fold cross-validation strategy was applied for training and testing. Dice similarity coefficient (DSC) was adopted to evaluate the network\u2019s performance.<jats:italic> Results<\/jats:italic>. It took about 1.5s for our CNN model to perform the segmentation task in a slice of MRI image. The mean DSC of 58 patients was 0.74\u00b1 0.17 and the median DSC was 0.79. Compared with other DL models, our CNN model achieved better performance in DVT segmentation (0.74\u00b1 0.17 versus 0.66\u00b10.15, 0.55\u00b10.20, and 0.57\u00b10.22).<jats:italic> Conclusion<\/jats:italic>. Our proposed DL method was effective and fast for fully automatic segmentation of lower extremity DVT.<\/jats:p>","DOI":"10.1155\/2019\/3401683","type":"journal-article","created":{"date-parts":[[2019,6,9]],"date-time":"2019-06-09T19:30:55Z","timestamp":1560108655000},"page":"1-7","source":"Crossref","is-referenced-by-count":28,"title":["Fully
