Thirty-three patients with 35 bone lesions suspicious for osteosarcoma underwent image-guided biopsy. Of those 35 biopsies, 12 were performed with use of fluoroscopy or computed tomography (CT) guidance to target the osseous abnormality. Diagnostic magnetic resonance imaging revealed a soft tissue component in 23 cases; in these cases, biopsies were performed with use of ultrasonography (US) to target the soft tissue component of the tumor. Of the 35 tumors in which biopsy was performed, 33 (94%) were definitively diagnosed as osteosarcoma by image-guided biopsy. All 23 US-guided biopsies resulted in definitive diagnosis. Two of the 12 fluoroscopy- or CT-guided biopsies (17%) were inconclusive.
