Clinical significance of abdominal computed tomography and colonoscopy in the evaluation of phlebosclerotic colitis.

Clinical manifestations of phlebosclerotic colitis (PC) exhibit significant variability, necessitating diverse treatment strategies depending on disease severity. However, there is limited research exploring the relationship between imaging findings and disease severity. Hence, this retrospective study aimed to analyze the correlation between computed tomography (CT) findings, colonoscopic features, and disease severity.

Deep Learning Approach for Negation and Speculation Detection for Automated Important Finding Flagging and Extraction in Radiology Report: Internal Validation and Technique Comparison Study.

Background: Negation and speculation unrelated to abnormal findings can lead to false-positive alarms for automatic radiology report highlighting or flagging by laboratory information systems.

Objective: This internal validation study evaluated the performance of natural language processing methods (NegEx, NegBio, NegBERT, and transformers).

Methods: We annotated all negative and speculative statements unrelated to abnormal findings in reports.
