The progression of emphysema is traditionally measured by pulmonary function test, with forced expiratory volume in 1 s (FEV(1)) being the most accepted and used measurement. However, FEV(1) is insensitive in detecting mild/slow progression of emphysema because of low reproducibility as compared to yearly decline. ⋯ This pilot study indicates the possible use of nonionizing HP (3)He MRI for monitoring the progression of emphysema. However, in the future, larger studies are needed to confirm these preliminary results.

T2 relaxation time mapping of proximal tibiofibular cartilage by 3-tesla magnetic resonance imaging.
The proximal tibiofibular joint (PTFJ) can be considered the fourth compartment of the knee joint. However, there have been no studies of the T2 values (T2 relaxation time) of PTFJ cartilage. ⋯ PTFJ cartilage showed shorter and more homogeneous T2 values with a small SD than did MFC cartilage, regardless of the degree of OA at femorotibial compartments. PTFJ cartilage may be a useful internal standard reference to diagnose OA and would be a good candidate as a standard reference for cartilage imaging.
