Our most recent research paper entitled “Precise diagnosis of intracranial hemorrhage and subtypes using a three-dimensional joint convolutional and recurrent neural network” has been accepted for publication in European Radiology*. 

In this study, our scientists have proposed a novel three-dimensional joint convolutional and recurrent neural network (CNN-RNN) for the detection of intracranial hemorrhage. To the best of our knowledge, our proposed algorithm is the first end-to-end trainable 3D ICH detection deep learning network that seamlessly integrates CNN and RNN while providing the flexibility of training when only subject-level labels or slice-level labels are available.

In the study, the performance of our algorithm was generally superior to the average performance of the junior radiology trainees for both two-type and five-type classification tasks. Our algorithm detected on average 90% of the true positives identified by the junior radiology trainees. In addition, our algorithm captured 11 subarachnoid hemorrhage-positive cases that none of the junior radiology trainees diagnosed correctly. Our proposed method was able to accurately detect ICH and its subtypes with fast speed, taking less than 30 seconds on average to process a 3D CT scan. This suggests the potential for our algorithm to assist radiologists and physicians in their clinical diagnosis workflow in the future.
