T1ρ-mapping is a promising quantitative technique to
detect cartilage damage at an early stage, at which
tissue damage might be reversible. Here we test the
feasibility of high resolution T1ρ-mapping mapping of
articular cartilage at 3T. T1ρ-mapping was performed
using a T1ρ-prepared 3D FFE sequence. 4 images with
different spin-lock (SL) preparation times with an
amplitude of 500 Hz were acquired (SL = 1,12,24,48 ms).
The T1ρ-relaxation time in the articular cartilage in
healthy subjects was 572 ms. High resolution
T1ρ-mapping of the wrist at 3T is feasible, and a
promising technique to assess early cartilage damage in
the wrist.
