Purpose

To evaluate the usefulness of diffusion-weighted (DWI) magnetic resonance for different types of thoracic wall sarcoma.

Methods and materials

We enrolled 72 patients with thorax wall sarcoma using Ultra sound with color Doppler, MDCT 16 and 64 with perfusion and MRI 1.5T with T1W, T3W, 3D troofy, fat suppression and T2W diffusion. Patients were from 12 to 74 years old. Male were 41 (56.94%), female 31 (43.06%). Fine needle biopsy was performed in 24 patients.

Results

The enrolled patients had 72 solid masses. Although the morphological features and the extent of enhancement on US and CT did not differ significantly between types of sarcoma (P>0.05), sarcoma were distinguishable from solid masses by showing signal suppression on high-b-value DW images or high apparent diffusion coefficient (ADC) values. Liposarcoma were in 11 cases with ADC values of 1.56±0.87×10-3 mm2/s (P<0.001). Chondrosarcoma were in 15 cases with ADC values of tuberculoma 2.11±0.87×10-3 mm2/s (P<0.001). Malignant peripheral nerve sheath tumor were in 5 cases with...

Conclusion

DWI can help differentiate thoracic wall sarcomas, even when US and CT findings are questionable.
