When discussing how radiology reports should be written, two approaches are often positioned against each other: free-text reporting and structured reporting. On one side is free text, which preserves the radiologist’s natural narrative style and case-specific flow of thought. On the other is structured reporting, which uses predefined headings, fields, and standardized phrases.
Treating these approaches as though one is correct and the other is wrong does not adequately reflect daily practice. A strong template may offer major advantages in simple, repetitive examinations, while a rigid structure may make communication more difficult in a complex multisystem case. The more useful question is:
What level of structure communicates the clinical message of this examination most clearly and safely?
Free-text reporting means describing findings and interpretation without being restricted to predefined mandatory fields. A free-text report does not have to be completely unstructured; it may still include basic sections such as “Findings” and “Impression.” Its defining feature is that the order of content and sentence construction are created largely by the user during the case.
Structured reporting means creating a report through defined sections, subheadings, selectable fields, or standardized sentences. The degree of structure may vary.
This approach provides a basic organization for most daily reports while leaving the findings section largely flexible.
The findings are divided into anatomical or system-based subheadings:
The user may write free text under each heading or select prepared phrases.
The report may include measurement fields, drop-down selections, mandatory data elements, and automatic impression generation. This approach is particularly visible in systems such as TI-RADS, PI-RADS, BI-RADS, and oncologic response assessment.
A well-designed template reminds the user of the core areas that should be assessed. Especially during residency, it can function as a checklist.
Reporting the same examination with a similar sequence and terminology helps readers locate important information more quickly.
Entering individual features and generating a category based on those features may help classification criteria be applied more systematically. Any automatically generated category or recommendation must still be verified by the user.
A template can remind a new user how to write the report and what to evaluate. An RSNA-published review has highlighted that structured reporting may be particularly helpful for users in the early stages of training.
Standard headings and defined data elements may make information easier to retrieve for quality improvement, registries, and research.
As users move automatically through fields, they may leave “normal” options in place without adequately considering an unusual finding. A completed-looking template does not necessarily mean the examination has been fully assessed.
Describing every normal structure in detail can make an important finding less visible. Structure and length are not the same thing.
A default negative statement may remain in the template after a positive finding is added to the same section:
No pleural effusion is present. A moderate right pleural effusion is present.
These errors occur when the entire report is not actively reviewed.
In trauma, extensive malignancy, postoperative anatomy, or multisystem disease, a routine template may fragment the diagnostic relationship between findings.
Automatically transferring findings into the impression can create repetition rather than synthesis. The impression is often the section with the greatest clinical value and usually requires active reasoning.
Assume a noncontrast head CT was performed after a fall to exclude acute intracranial hemorrhage.
Brain parenchyma is normal. Ventricles are normal. No skull fracture. No hemorrhage. Midline structures are in place. Mild mucosal thickening in the sinuses.
The report contains the basic message, but the order and terminology may vary greatly between users. The acute traumatic findings that matter most clinically are not prioritized in the impression.
Cerebral hemispheres: Normal. Basal ganglia: Normal. Thalami: Normal. Brainstem: Normal. Cerebellum: Normal. Ventricular system: Normal. Sulci: Normal. Cisterns: Normal. Paranasal sinuses: Minimal mucosal thickening in the maxillary sinuses. Mastoid air cells: Normal. Osseous structures: Normal.
This format appears comprehensive, but the answer to the trauma question may become lost among lengthy normal findings.
Findings: No acute intracranial hemorrhage, significant mass effect, or midline shift. The ventricular system and basal cisterns are normal in caliber. No acute calvarial fracture. Mild mucosal thickening is present in the maxillary sinuses.
Impression: No acute traumatic intracranial abnormality.
This example preserves a standard review framework while keeping the report focused on the clinical question.
Structured reporting may be a particularly strong option in the following situations:
Examples include:
Details and current versions of these systems should be confirmed from the relevant official guidelines.
In these cases, the basic headings can be retained while the findings are organized as problem-oriented paragraphs or flexible narrative text.
In daily practice, the most balanced solution is often a hybrid model:
The hybrid model treats the template as a starting point, not a finished product.
When choosing a reporting style for an examination, consider the following questions:
Free text provides flexibility and nuance, while structured reporting provides coverage, consistency, and reusability. Good reporting is not an ideological choice between the two. It means using as much structure as the examination and clinical question require.
During residency, templates can provide powerful learning support. The goal, however, is not to complete every template field. It is to turn an accurate imaging assessment into a clear, prioritized, and clinically usable message.
