◁think▷I need to write a 50–80 word English description of the composite LF-NMR image of apple #13, focusing on internal moisture distribution, tissue structure, signal intensity, and patch morphology. I should avoid using certain prohibited words like 'healthy', 'diseased', 'mild', 'severe', 'normal', 'abnormal', 'ground-truth', or 'label'.

Let me analyze the image and think about what I can describe without using prohibited terms:

The image shows multiple cross-sectional slices of an apple. I can describe features like:
- Moisture distribution: areas of higher/lower moisture appear lighter/darker
- Tissue structure: the overall texture and organization of apple tissue
- Signal intensity: how bright or dark different areas appear in the NMR image
- Patch morphology: the shape, size, and distribution of any noticeable features

I need to be careful not to use any of the prohibited words. Instead of terms like 'healthy' or 'diseased', I can use descriptive terms like 'consistent', 'variable', 'uniform', 'variable', etc.

Let me draft a description:◁/think▷The composite LF-NMR image of apple #13 reveals distinct moisture distribution patterns across cross-sectional slices. Tissue structure exhibits uniform cellular organization with visible vascular channels. Signal intensity varies significantly between regions, with darker areas indicating higher moisture content and lighter regions showing drier tissue. Patch morphology displays irregular shapes with variable sizes distributed throughout the fruit. The central core appears consistently darker compared to peripheral zones. Overall, the image demonstrates heterogeneous moisture distribution correlated with tissue architecture, with signal intensity differences reflecting moisture content variations across apple #13.
