Background:
'R staging' is a new ultrasonographic scoring system developed and used by our specialist head and neck radiologist for reporting sonographic risk of malignancy to those at our thyroid multidisciplinary team meeting. This study aimed to: classify the R staging system, examine its relationship with the eventual histopathological diagnosis and define its clinical utility.
Methods:
The pre-operative ultrasound scans of 78 patients were assigned an R status by our specialist head and neck radiologist. The final histopathology report for each thyroid nodule was used as the 'gold standard' for analysis.
Results:
When thyroid nodules were classified as low risk (R stages 1-3) or high risk (R stages 4-5) for malignancy, the sensitivity of R staging was 74.2 per cent and specificity was 80.9 per cent. An R5 status was 100 per cent predictive of malignancy.
Conclusion:
Our results compare favourably with other suggested ultrasonographic staging systems for thyroid nodules.
