Fig. 3From: External validation study on the value of deep learning algorithm for the prediction of hematoma expansion from noncontrast CT scansA Initial CT scan image of a 51-year-old female HICH patient. The patient was diagnosed with hematoma expansion by the doctor according to CT signs. B Follow-up CT scan within 6Â h after the initial scan, the hematoma volume increased by 12.9Â ml, and was confirmed as hematoma expansion. C AI software automatically analyzed the initial CT scan image of the patient after onset. The blue colored mask refers to the delineation of hematoma and the prediction of hematoma expansion by AI software was shown in the right sideBack to article page
