Purpose: To identify whether there was an association between Hounsfield units of sclerotic bone lesions and diagnostic yield of biopsy.
Method: All core needle biopsies of sclerotic bone lesion were identified from a database. Pathology reports were reviewed to determine whether the biopsy was diagnostic or non-diagnostic.
Results: 91 patients were included in the study group. The yield for lesions with mean HU≥500 was significantly lower than those with a mean HU≤500 (40% vs. 69.6%, p<0.05).
Conclusion: Lesions with a mean HU>500 are more likely to have a non-diagnostic biopsy than a diagnostic biopsy.
