Update on MR Imaging Techniques of the Hip

Area of Science:

• Radiology
• Medical Imaging
• Orthopedics

Background:

• Standard hip MR imaging uses T1-weighted and fluid-sensitive sequences in multiple planes.
• MR arthrography is valuable for evaluating intra-articular hip pathologies.
• Assessing intra-articular structures like cartilage and labrum requires optimized imaging.

Purpose of the Study:

• To outline optimal MR imaging protocols for hip assessment.
• To discuss the role of MR arthrography in diagnosing intra-articular hip pathology.
• To introduce emerging quantitative MR techniques for cartilage evaluation.

Main Methods:

• Routine hip MR imaging involves T1-weighted and fluid-sensitive sequences.
• MR arthrography visualizes intra-articular hip structures.
• Quantitative techniques include T1ρ, T2 mapping, and delayed gadolinium-enhanced MR imaging.

Main Results:

• Optimized protocols are crucial for diagnostic accuracy in hip MR imaging.
• MR arthrography effectively assesses cartilage, labrum, and intra-articular bodies.
• Quantitative MR techniques can detect biochemical changes in cartilage degeneration.

Conclusions:

• Hip MR imaging requires optimized protocols and technical parameters for best results.
• MR arthrography is a key tool for intra-articular hip pathology.
• Emerging quantitative MR techniques offer new insights into cartilage health and osteoarthritis.
