Multi-exponential MRI T2 maps: A tool to classify and characterize fruit tissues

Guylaine Collewet et al.

Summary: Recent developments in image processing have allowed for the estimation of multi-exponential relaxation time T2 and their associated amplitudes A0 at the voxel level. However, these data represent a large amount of information and are not easily interpretable, and the non-uniformity of MRI images may lead to interpretation errors. In this paper, a post-processing scheme that clusters similar voxels according to the multi-exponential relaxation parameters is proposed to reduce the complexity of the information and avoid problems associated with intensity non-uniformity. A data representation suitable for visualizing the multi-T2 distribution within each tissue is also suggested.

Characterization of the Water Shortage Effects on Potato Tuber Tissues during Growth Using MRI Relaxometry and Biochemical Parameters

Ghina Hajjar et al.

Summary: This study investigated the variations in biochemical traits of different tissues during potato tuber growth. MRI relaxometry was used to examine tissue-dependent metabolic patterns and differences between tissues. The T2 values did not significantly change during tuber development but were sensitive to water stress.

Spatial and temporal evolution of quantitative magnetic resonance imaging parameters of peach and apple fruit - relationship with biophysical and metabolic traits

Maja Musse et al.

Summary: Fruits undergo spatial evolution of biophysical and metabolic traits during development, with magnetic resonance imaging being able to capture tissue evolution and the development of pericarp heterogeneity, demonstrating its usefulness as a tool to phenotype fruits and obtain important physiological data.

MRI investigation of internal defects in potato tubers with particular attention to rust spots induced by water stress

Ghina Hajjar et al.

Summary: The study used MRI technology to evaluate internal defects in potato tubers, focusing on rust spots induced by water stress. It was found that the occurrence of rust spots correlated with water conditions in the greenhouse and increased with tuber size.
