Cholangiocarcinoma: Epidemiology and Imaging-Based Review.

Cholangiocarcinoma (CCA) is a rare cancer of the bile duct epithelium, and in the last few decades its incidence rate has been increasing. It is associated with a high mortality rate due to late diagnosis and its aggressive nature. Many risk factors have been identified; some are more common in certain regions than others. CCA can be classified according to its anatomical location or macroscopic growth pattern, the latter being most helpful for imaging interpretation. Clinical features can vary from obstructive-like symptoms to nonspecific symptoms, such as weight loss and malaise. Imaging, specifically MRI/MRCP, is crucial in diagnosing CCA, staging, and treatment planning. Surgery with chemotherapy is the mainstay treatment option, and other palliative treatment options exist for those who have unresectable disease.

Using ChatGPT to Improve Readability of Interventional Radiology Procedure Descriptions.

PURPOSE: This project examines ChatGPT's potential to enhance the readability of patient educational materials about interventional radiology (IR) procedures. METHODS AND MATERIALS: The descriptions of IR procedures from the Cardiovascular and Interventional Radiological Society of Europe (CIRSE) were used as the original text. Readability scores were calculated using three metrics: Flesch Reading Ease (FRE), Gunning Fog (GF), and the Automated Readability Index (ARI) using an online calculator ( https://readabilityformulas.com ). FRE is scored on a scale of 0-100, where 100 indicates easy-to-read texts, and GF and ARI represent the grade level required to comprehend the text. The DISCERN instrument measured credibility and reliability. ChatGPT was prompted to simplify the texts to a fifth-grade reading level, with subsequent recalculation of readability and DISCERN scores for comparison. Statistical significance was determined using a Wilcoxon Signed-Rank Test. Articles were subsequently organized by subgroups and analyzed. RESULTS: 73 interventional radiology procedures from CIRSE were analyzed. The original FRE score was 47.2 (Difficult), improved to 78.4 (Fairly Easy) by ChatGPT. GF and ARI scores dropped from 14.4 and 11.2 to 7.8 and 5.8, respectively, after simplification, showing significant improvement (p < 0.001). However, the average DISCERN score decreased from 3.73 to 2.99 (p < 0.001) post-ChatGPT simplification. CONCLUSION: This study shows ChatGPT's ability to make interventional radiology descriptions more readable but highlights its struggle to maintain the original's reliability, suggesting the need for human review and prompt engineering to enhance outcomes. LEVEL OF EVIDENCE: Level 6.
