1.5-T MRI of the arm (proton density [PD] fat saturation [FS]: 6 consecutive slices of 3 mm) of a 54-year-old patient. The higher-grade polycyclic/multilobulated sarcoma in the upper arms shows solid (white arrow) and cystic (white arrowhead) components.

1.5-T MRI of the pelvis (A) proton density [PD] axial, (B) contrast-enhanced T1 fat saturation [FS] axial, (C) PD sagittal) of a 49-year-old patient. The higher-grade polycyclic/multilobulated sarcoma in the right pelvis (white arrow) shows heterogeneous contrast enhancement (black arrow), infiltrative behavior (black arrowhead), and solid components within cystic tissue (white arrowhead).

1.5-T MRI of the abdomen (A) contrast-enhanced T1 axial, (B) contrast-enhanced T1 sagittal) of a 41-year-old patient. The low-grade sarcoma in the right abdominal wall (white arrow) presents with a ovoid/nodular configuration.

1.5-T MRI of the upper arm (A) contrast-enhanced T1 axial, (B) contrast-enhanced T1 sagittal) of a 48-year-old patient. The higher-grade sarcoma in the subcutaneous tissue (white arrow) has a streaky configuration and shows slight infiltration of the surrounding subcutaneous tissue.

Overview of configuration of high-grade (G3), intermediate-grade (G2) and low-grade (G1) soft-tissue sarcomas (STS)_ Additional information on tumor infiltration (infiltrative or well-defined), contrast enhancement (homogeneous or heterogeneous), and volume in “cm3” is shown
