Rapid Radial T₁ and T₂ Mapping of the Hip Articular Cartilage With Magnetic Resonance Fingerprinting.

ABSTRACT:

Background

Quantitative MRI can detect early changes in cartilage biochemical components, but its routine clinical implementation is challenging.

Purpose

To introduce a novel technique to measure T₁ and T₂ along radial sections of the hip for accurate and reproducible multiparametric quantitative cartilage assessment in a clinically feasible scan time.

Study type

Reproducibility, technical validation.

Subjects/phantom

A seven-compartment phantom and three healthy volunteers.

Field strength/sequence

A novel MR pulse sequence that simultaneously measures proton density (PD), T₁ , and T₂ at 3 T was developed. Automatic positioning and semiautomatic cartilage segmentation were implemented to improve consistency and
