Meniscal tears are an indication for arthroscopic knee
surgery. The tears in the vascular portion of the
meniscus is called red zone and tears in the
avascular portion is defined white zone. Although
the demarcation of the zones can be defined in anatomy,
it is hard to gain a boundary through conventional MR
sequence. Intravoxel incoherent motion theory provides
information about microcirculation of blood in addition
to the pure molecular diffusion. In this study, rFOV DWI
technology and IVIM model were used to estimate the
vasculature of the red and white zone of meniscus by
using the IVIM perfusion parameters.
