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 4.37±0.87×10-3 mm2/s (P<0.001).
Soft tissue sarcomas were in 4 cases with 3.44±0.87×10-3 mm2/s (P<0.001).
Bone tumors were in 37 cases with 6.24±0.87×10-3 mm2/s (P<0.001).
One case was undefined sarcoma with 5.14±0.87×10-3 mm2/s (P<0.001) and 1 with dermatofibrosarcoma protuberance with 2.78±0.87×10-3 mm2/s (P<0.001).
According to grade there were 15 (20.83%) low,
22 (30.56%) intermediate and 35 (48.61%) patients with high grade sarcoma.
According to age of patient,
younger patients had higher grade sarcomas.
