ABSTRACT
PURPOSE:
To review MRI in order to compare Gd-DTPA enhanced images before and after preoperative intraarterialchemotherapy for osteosarcoma. MATERIALS ANDMETHODS:
In sixteen patients with pathologically-proven osteosarcomawho underwent intra-arterial chemotherapy, MR images were obtained before and after this treatment. The degree[grade 0(low) to IV(high)] and pattern (homogenous, inhomogenous) of changes in contrast enhancement and tumorsize were evaluated.RESULTS:
Enhancement changed from Grade III to I in eight patients and from Grade III to IIin five. In three, the enhancement pattern changed from homogenous to inhomogenous; in ten, the inhomogenouspattern did not change; and in three, there was a change from thick, irregular to thin, smooth-rimmed enhancement.In all patients except one, the intraosseous tumor component was not changed. The extraosseous component becamelarger in three patients, smaller in two, and showed no size change in eleven.CONCLUSION:
In osteosarcoma, MRimaging after Gd-enhancement following intra-arterial chemotherapy showed decresased enhancement, and increasedinhomogeneity and smooth rim enhancement. Neither the intra-nor extraosseous tumor component showed size changewith time.
