MRI of Soft-Tissue Tumors: What to Include in the Report

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Magnetic Resonance Imaging (MRI) is integral to the workup, staging, and treatment planning of extremity soft-tissue masses.
• Accurate interpretation requires a detailed, organized report with specific lesion descriptors.

Purpose of the Study:

• To outline essential MRI descriptors for evaluating soft-tissue masses, particularly sarcomas.
• To enhance radiologists' contributions to mass management, including differential diagnosis and treatment planning.

Main Methods:

• Review of MRI features relevant to soft-tissue mass evaluation.
• Identification of descriptors critical for differential diagnosis and surgical planning.

Main Results:

• Key descriptors include borders, shape, signal characteristics, enhancement patterns, edema, lymph node status, location, size, and vascularity.
• These descriptors aid in narrowing differential diagnoses and optimizing surgical and oncologic treatment strategies.

Conclusions:

• Standardized MRI reporting with specific descriptors improves diagnostic accuracy and facilitates multidisciplinary patient management.
• This approach is particularly vital for soft-tissue sarcomas, ensuring concordance with pathology and grade.
