Four-category framework for diagnostic abdominal imaging artifacts

A four-category framework (Virtual Biopsy, Flowmeter, Signpost, Tiebreaker) turns abdominal imaging artifacts into diagnostic clues, not pitfalls, helping radiologists interpret CT, MRI, ultrasound, and other modalities.

• Intended for radiologists and trainees interpreting abdominal imaging, this pictorial essay teaches a systematic approach to artifacts and related phenomena (ARPs).
• Virtual Biopsy helps characterize tissue composition; Flowmeter reveals flow states; Signpost directs attention to pathology; Tiebreaker prompts multi-modality correlation.
• Representative cases illustrate each category across modalities, embedding ARPs into diagnostic reasoning rather than dismissing them as errors.
