◁think▷I need to write a 50–80 word English description of the composite LF-NMR image of apple #17, 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:

The image shows four cross-sectional views of an apple. I can observe:
1. The internal structure of the apple, including the core and surrounding tissue
2. Variations in signal intensity across different regions
3. Moisture distribution patterns (darker areas might indicate higher moisture)
4. Tissue structure variations (some areas appear more fibrous or structured than others)
5. Possible patches or areas with different morphologies

I need to describe these observations without using the prohibited terms. I'll focus on objective features like:
- Variations in brightness/darkness (which might relate to moisture)
- Texture differences (which relate to tissue structure)
- Patterns across the cross-sections
- Any noticeable patches or areas with distinct characteristics

I'll craft a concise description that captures these observations while staying within the word limit and avoiding prohibited terms.◁/think▷The composite LF-NMR image of apple #17 displays distinct cross-sectional views revealing internal moisture variations characterized by darker regions indicating higher water content. Tissue structure exhibits fibrous patterns with noticeable differences between core and peripheral areas. Signal intensity varies significantly across sections, with some regions showing brighter, more homogeneous areas and others appearing grainier and less uniform. Morphological patches are evident, particularly in the upper sections where tissue organization appears more disrupted. The lower portions demonstrate denser structural arrangements with consistent signal patterns throughout the cross-sections.
