The water and macromolecular environment determine the T1 relaxation time of tissues,[38] so T1 is markedly decreased in the ZCC as compared to the superficial cartilage in knees.[39] Furthermore, increased T1 is associated with cartilage degeneration.[25] In the ZCC, the short T1 component accounts for about 70% of the signal, with another 30% from the adjacent long T1 component likely to be due to the partial volume effect.[40]

These new techniques substantially improve image quality and reduce the partial volume effect (PVE) [14].
Another problem is that the magnitudes of [DELTA][Hb[O.sub.2]] and [DELTA][HHb] are underestimated due to the so-called partial volume effect (PVE) [16].
In particular, efficient formation of Si nanocrystals with the sizes of 2-7 nm and partial volume of a crystalline phase of up to 80% was demonstrated in the recent experiments on low-temperature crystallization of [alpha]-Si with Tin (Sn) [18-20].
Further issues are related to the variable orientation of the nerve along its course, which may lead to partial volume effects and magic angle artifacts, secondary to the anisotropic architecture of the nerve fibers [14].

Although AD[C.sub.WF] and AD[C.sub.SF] were measured from the coregistered fibroglandular tissue from the segmented FT mask, there was inevitably partial volume effect with fat, especially in the boundary of the FT mask adjacent to the fatty tissue.
Partial volume was calculated by interpolating the four QF CSAs in order to determine whether the most proximal image CSA was representative of the whole muscle.
Previous resolution based research demonstrated the quality of images in MRI at the expense of signal to noise ratio, the acquisition time and partial volume effect but work on low resolution using QSM was not explored well12, 13.
