Abstract: Four types of images of kiwifruit, i.e., proton density、diffusion coefficient D distribution、T1 distribution、T2 distribution magnetic resonance image, have been measured on a 4.7T mini imaging system. The T1、T2 and D values corresponding to different parts of kiwifruit were extracted. Three water suppressed ¹H localized spectra were obtained and compared with a high resolution NMR spectrum of kiwifruit juice. The useful information about the morphological structure and material composition of the kiwifruit has been therefore noninvasively gotten.

Key words: Kiwifruit, Magnetic resonamce image, Localized spectroscopy
