How should a new finding or interval change be described in a radiology report?

• A. Use 'new' or 'interval change' for new findings; 'known' or 'chronic' for previously described abnormalities, and indicate stability or progression
• B. Use 'new' only
• C. Use 'unchanged' for new findings
• D. Use 'historical'

Answer: (A)

In radiology reporting, the main idea is to clearly distinguish what’s new from what’s already known, and to show how findings have changed since prior imaging. When something is new or there’s a change since the last study, describe it as “new” or as an “interval change.” This flags to the clinician that this finding wasn’t seen before and may require follow-up or further work-up. If something is a preexisting abnormality, label it as “known” or “chronic,” and then state whether it’s stable or has progressed compared with prior studies. This combination of terminology helps the care team understand the patient’s current status and the action, if any, that’s needed. For example, reporting a newly seen nodule as “new pulmonary nodule in the right upper lobe” communicates its novelty, while noting “interval change with monitoring recommended” guides follow-up. If a known lesion is present and has not changed, describing it as “known nodule, stable on interval imaging” conveys stability. If it has grown, you’d say “known nodule, interval progression,” which matters for management decisions. The key is to pair new findings with interval-change language and preexisting findings with known/chronic language plus a note on stability or progression. Other phrasing that omits these distinctions can mislead: describing something as unchanged for a new finding is confusing, and using only “historical” doesn’t clearly convey the current finding or its relationship to prior studies. The preferred approach combines new or interval-change wording with known or chronic for prior abnormalities, along with whether they’re stable or progressing.
