"Due to the type and problem complexity, a dense neural network was chosen to provide accurate answers.". This continues until each is used as a validation set, resulting in 10 different models with unique validation sets. Artificial Intelligence, RSNA 2017, deep learning The role of deep learning (DL) and artificial intelligence (AI) within radiology continues to spark both fear and interest, yet the reality is that they are both potentially very useful technologies that will add value to the field in many ways. There were 704 confirmed malignant nodules in the lung cancer X-rays (78.6% primary lung cancers and 21.4% metastases). While skin dose has been the primary concern in neuro-interventional procedures because of the potential for radiation-induced skin injuries, these procedures also have the potential for a high dose to the patient's eye lens, explained Jacob Collins, MS, a PhD student at the University at Buffalo, State University of New York. In fact, the dose often exceeds 500 mGy, the amount estimated by the International Commission on Radiological Protection to induce cataracts. The readers then re-read the same X-rays with the assistance of DCNN software, which was trained to detect lung nodules. NVIDIA Deep Learning Institute presents a weeklong RSNA Deep Learning Classroom, to include nearly two-dozen 90-minute courses, including introductory courses and specialty topics.
