Core Tip

Core tip: Radiological tumor size estimation of pancreatic neuroendocrine tumors is of utmost importance for therapeutic decision-making, especially for non-functioning ones. This study showed that both magnetic resonance and computer tomography are accurate and interchangeable in predicting pathologic tumor size.
