◁think▷I need to write a 50–80 word English description of the composite LF-NMR image of apple #31, focusing on internal moisture distribution, tissue structure, signal intensity, and patch morphology. I should avoid certain prohibited words and not output JSON, Chinese, or extra explanations.

Let me analyze what I can observe from the image:

1. The image shows cross-sectional views of an apple's interior
2. There appear to be multiple slices or cross-sections arranged in a grid
3. The texture within the apple appears somewhat granular or uneven
4. There are variations in signal intensity (brighter and darker areas)
5. The overall structure suggests variations in moisture content and tissue density

For the description, I should:
- Highlight moisture distribution (areas of higher/lower moisture)
- Describe tissue structure (how the apple's internal tissues appear)
- Mention signal intensity variations (brighter/darker areas)
- Note any notable patch morphology (patterns or formations of moisture or tissue)

I need to avoid these words:
- healthy
- diseased
- mild
- severe
- normal
- abnormal
- ground-truth
- label

I'll craft a concise description that covers the required elements without using prohibited terms.◁/think▷The composite LF-NMR image of apple #31 reveals a complex internal moisture distribution with distinct regions of higher and lower signal intensity. Tissue structure appears heterogeneous, showing both dense and porous areas. Patch morphology is evident through irregularly shaped regions with varying signal characteristics. The arrangement suggests natural variations in apple anatomy, with some slices displaying more pronounced moisture patterns than others. Overall, the image provides detailed information about the apple's internal composition through non-destructive NMR imaging techniques.
