Trabecular bone is made up of a network of microstructures (80\u2013140 \u03bcm), and its structural deterioration is associated with the skeletal metabolic disorder osteoporosis. HR\u2010MRI is a promising noninvasive tool for assessing the trabecular microarchitecture in vivo, but it involves long acquisition times. Using partially parallel imaging (PPI) to accelerate the acquisition may help mitigate this shortcoming and allow more flexibility in protocol design. In this study the effects of GRAPPA\u2010based reconstruction on image characteristics and the measurement of trabecular bone structural parameters were evaluated. Initial studies showed that image quality and depiction of microstructure were preserved in the GRAPPA\u2010based reconstruction, indicating the feasibility of PPI in HR\u2010MRI of trabecular bone. The results also demonstrated the potential of PPI for increasing the signal\u2010to\u2010noise ratio (SNR) efficiency of multiple\u2010acquisition b\u2010SSFP imaging protocols.
