Purpose. To compare the diagnostic capabilities of magnetic resonance and computed tomography in the detection of metastatic bone lesions in patients with renal cell carcinoma.

Materials and methods. The study involved 11 patients with renal cell carcinoma (RCC) with metastatic bone damage. All patients underwent magnetic resonance and computed tomography.

Results. The average tumor volume in MRI was 44.1% more compared to the average volume in computed tomography (CT), which was both clinically and statistically significant. In 11 of 17 lesions, the volume of metastases was greater on magnetic resonance imaging (MRI) compared with the volume on CT. In 6 of 17 lesions, the volumes were comparable in size.

Conclusion. Diagnosis of bone metastases of RCC on MRI led to both clinically and statistically significant large volumes compared to measuring the same lesions on CT. MRI more accurately reflects the extent of lesions in metastasis, due to better visualization of bone marrow infiltration and soft tissue invasion. A contouring based only on CT can lead to an underestimation of the actual tumor volume, which can lead to an incorrect planning of radiotherapy.
