• The plumpness of hepatopancreas and gonad tissues in live Chinese mitten crabs (Eriocheir sinensis) depends on the grading scale and its commercial value. In this work, a low-field T -weighted H magnetic resonance imaging (LF- H MRI) technique was developed to nondestructively analyze the plumpness of hepatopancreas and gonad tissues in live E. sinensis. Both male and female E. sinensis were characterized by two-dimensional (2D) LF- H MRI. Moreover, a three-dimensional (3D) LF- H MRI model that quantitatively integrated the total volume of lipid tissues in live E. sinensis was used. The results showed 2D LF- H MRI could accurately discriminate the plumpness of hepatopancreas and gonad tissues in live E. sinensis. The results of the 3D LF- H MRI model displayed that the lipid volume of E. sinensis could be used to quantify lipid accumulation in lipid tissues. LF- H MRI technology was successfully developed to accurately discriminate the development of E. sinensis hepatopancreas and gonad tissues in a nondestructive manner, indicating its application potential in grading commercial live crabs or advising crab farmers on breeding and fattening processes. © 2018 Society of Chemical Industry.
