Answer

The American College of Radiology (ACR) Appropriateness Criteria for soft-tissue masses include the following recommendations [8] :

  • The initial imaging study for a superficial or palpable soft-tissue mass should be radiographs.
  • US is equally appropriate for small lesions that are superficial to the deep fascia.
  • For deep masses or lesions in areas difficult to evaluate radiographically (ie, groin, paraspinal area, deep soft tissues of the hands and feet, or flank), radiographs are also usually appropriate.
  • If the initial evaluation of soft-tissue masses is nondiagnostic, further evaluation with MRI without and/or with IV contrast is usually appropriate.
  • In patients presenting with spontaneous hemorrhage or suspicion of a vascular mass, if the initial evaluation is nondiagnostic, further evaluation with either MRI without and with IV contrast or CT without and with IV contrast is usually appropriate.
  • If the initial evaluation of a soft-tissue mass is nondiagnostic in patients who are non–MRI compatible or who have metal limiting MRI evaluation, CT with IV contrast or CT without and with IV contrast is usually appropriate as the next imaging study.
