Man Vs Machine: How Will Artificial Intelligence And Machine Learning Systems Impact Cancer Diagnosis And The Patient-Physician Relationship?, Aditya Kotha, Faye Prichard

Undergraduate Research Posters

Oncologic diagnosticians are physicians who specialize in interpreting diagnostic exams to diagnose cancer in patients. Software companies have been developing artificial intelligence (AI) systems to interpret these exams to diagnose cancer. These AI systems may affect the traditional role of oncologic diagnosticians if they were to be implemented in the clinical setting. Therefore, I set out to answer my research question: How will AI and machine learning systems impact the roles of oncologic diagnosticians in diagnosing cancer and the patient-physician relationship? By analyzing surveys and studies, I examined the attitudes of oncologic diagnosticians versus cancer patients toward implementing AI systems …
