This dataset is then used to train a convolutional neural network to classify images for cardiovascular abnormalities. We compare our augmentation strategy with traditional data augmentation and show higher accuracy for normal vs abnormal classification in chest X-rays. 展开 ...
Students were not informed of the number of normal/ abnormal cases. Students were required to describe each chest x-ray based on overall grayscale appearance of the image, size, shape and position of the heart and diagno- sis (see -Fig. 1). The criteria chosen in this case were in- ...

Automated classification of chest X-rays as normal/abnormal using a high sensitivity deep learning algorithm. In Proceedings of the European Congress of Radiology 2019, Vienna, Austria, 27 February–3 March 2019. [Google Scholar] Engle, E.; Gabrielian, A.; Long, A.; Hurt, D.E.; Rosenthal...
Chest-rAiTM aids the Radiologists to separate out Normal Vs Abnormal X-rays. It can bring down the estimated time for evaluating an X-ray by at least 50%, thereby enabling the Radiologists to use their time efficiently and optimally. Increased Efficiency by 5-6% With defined input data set...
We conclude that an abnormal x-ray film at discharge or during the hospitalization will identify approximately one-half of the abnormal ejection fractions at the time of hospital discharge. Therefore, to reliably assess left ventricular function, either for prognostic or therapeutic purposes in the ...
. Finally, while the AI system’s categories were designed to be mutually exclusive, there is a possibility that the expert radiologists interpreted the same abnormality on an X-ray differently and selected two different categories as abnormal when providing ground truth labels. Since the reference ...
