Use of Quantitative Descriptors in Radiology Reports
Yes, using terms like "a few" is standard and acceptable practice in radiology reporting, though it represents a balance between clinical practicality and the ideal of precise quantification.
Current Reporting Standards
While radiologic guidelines emphasize structured reporting and specific measurements for clinically significant lesions, they acknowledge that descriptive language remains part of routine practice, particularly for incidental or benign findings 1.
When Precise Quantification is Required
For clinically significant lesions (such as tumors, suspicious masses, or findings requiring follow-up), guidelines mandate specific measurements:
- Two-axis measurements are the minimum standard for lesions requiring monitoring 1
- Single-axis measurements are commonly used in clinical practice (preferred by 8 of 20 radiologists in expert panels) 1
- Volume measurements are reserved primarily for research settings due to time constraints 1
When Descriptive Language is Acceptable
For incidental or benign findings with low clinical significance, descriptive terms like "a few" are routinely used because:
- Time constraints: Radiologists face high imaging volumes and cannot precisely count every minor finding 1
- Clinical irrelevance: Small follicles or microcysts often have no clinical significance, making exact counts unnecessary
- Standardized terminology: Guidelines support using descriptive language when appropriate 2, 3
The Problem with Vague Language
Research demonstrates that ambiguous terminology creates significant interpretation variability:
- Radiologists, referring physicians, and patients interpret the same phrases differently 4, 5, 6
- Terms like "may represent" or "consistent with" show wide variability in perceived diagnostic certainty 7, 8
- Krippendorff's α of 0.217 indicates radiologists themselves don't consistently use phrases for similar confidence levels 7
Best Practice Recommendations
For your specific examples:
- "A few small follicles": Acceptable for physiologic findings in premenopausal patients, as exact counts rarely change management 9
- "A few microcysts": Acceptable if benign-appearing and <10 cm, as these typically fall into low-risk categories 9
When radiologists should be more specific:
- Any finding requiring follow-up imaging
- Lesions with malignancy risk
- Findings that could change clinical management
- When comparing serial examinations 1
Common Pitfalls
Avoid assuming vague language indicates uncertainty about significance. Often it reflects:
- The finding's benign nature
- Standard reporting conventions for incidental findings
- Time efficiency in high-volume practices
If concerned about a "vague" report, request clarification from the radiologist, particularly if:
- The finding requires follow-up
- Management decisions depend on the exact number
- Serial comparison is needed
Context Matters
The appropriateness of descriptive language depends entirely on clinical context:
- Ovarian follicles in fertility evaluation: Exact counts are essential
- Incidental follicles on abdominal MRI: "A few" is perfectly acceptable
- Liver lesions requiring surveillance: Precise number and measurements mandatory 9
- Incidental renal microcysts: Descriptive language appropriate if clearly benign
Structured reporting templates are increasingly recommended to reduce ambiguity 2, 3, 10, but descriptive language remains a practical necessity for minor incidental findings that don't warrant detailed quantification.
