MRI Visualization and Distribution Patterns of Foreign Modeling Agents: A Brief Pictorial Review for Clinicians

Area of Science:

• Cosmetic Dermatology
• Medical Imaging
• Pathology

Background:

• Historical use of physical appearance modification.
• Cultural beauty standards, particularly in Latin America, emphasize wider hips and buttocks.
• The ongoing search for safe, effective, and non-migrating injectable fillers.

Purpose of the Study:

• To provide a comprehensive assessment of injectable modeling agents.
• To summarize key imaging features of filler-related complications.
• To review classifications, adverse reactions, and detection methods for dermal fillers.

Main Methods:

• Literature review of historical data, epidemiology, and classifications of dermal fillers.
• Analysis of adverse reactions, imaging techniques (MRI), and histological findings.
• Presentation of case studies with infiltrative MRI patterns.

Main Results:

• Dermal fillers are classified by composition (xenografts, hyaluronic acid, autografts, etc.), degradation, and complications.
• Common adverse reactions and their imaging manifestations are detailed.
• MRI patterns are crucial for detecting filler migration and complications.

Conclusions:

• The review highlights the diverse landscape of injectable fillers and associated risks.
• Understanding imaging features is vital for diagnosing and managing filler complications.
• Continued research is needed for ideal, complication-free modeling agents.
