Imaging of lower limb cartilage

Area of Science:

• Orthopedics
• Radiology
• Biomedical Engineering

Background:

• Lower limb joint cartilage endures significant mechanical stress, leading to frequent degenerative and traumatic lesions.
• Magnetic resonance imaging (MRI) is the primary diagnostic tool for cartilage injuries.
• Current MRI sequences primarily identify morphological defects and cartilage loss.

Purpose of the Study:

• To review current morphological and emerging biochemical MRI techniques for cartilage assessment.
• To highlight the application of advanced MRI sequences in diagnosing common lower limb cartilage disorders.
• To emphasize the shift towards earlier detection of cartilage lesions through biochemical analysis.

Main Methods:

• Review of hyaline cartilage structure and function.
• Analysis of established morphological MRI sequences for cartilage evaluation.
• Detailed examination of novel quantitative, biochemical MRI techniques.
• Illustration of MRI sequence applications in common lower limb cartilage pathologies.

Main Results:

• Morphological MRI effectively visualizes cartilage defects and loss.
• Biochemical MRI sequences offer quantitative insights into cartilage matrix composition.
• Advanced MRI techniques show promise for earlier detection of cartilage degeneration.
• The study illustrates the utility of various MRI methods for specific lower limb joint conditions.

Conclusions:

• Biochemical MRI represents a significant advancement in cartilage assessment, enabling earlier detection of lesions.
• Integrating morphological and biochemical MRI provides a comprehensive evaluation of lower limb joint cartilage health.
• These advanced imaging techniques are crucial for timely diagnosis and management of cartilage disorders.
