◁think▷I need to write a 50–80 word English description of the composite LF-NMR image of apple #15, focusing on internal moisture distribution, tissue structure, signal intensity, and patch morphology. I should avoid certain prohibited words and not use JSON, Chinese, or extra explanations.

Let me analyze the image and think about what I can describe:

1. Internal moisture distribution: I can describe patterns of light and dark areas that might indicate moisture variations within the apple tissue.

2. Tissue structure: I can mention the overall texture and structural patterns visible in the cross-section of the apple.

3. Signal intensity: I can describe variations in brightness/darkness that might relate to different tissue components or moisture levels.

4. Patch morphology: I can identify and describe the shapes, sizes, and arrangements of distinct patches or regions within the apple.

Prohibited words to avoid: "healthy", "diseased", "mild", "severe", "normal", "abnormal", "ground-truth", "label".

Now, I'll craft a descriptive paragraph that covers these aspects without using prohibited words:◁/think▷The composite LF-NMR image of apple #15 reveals distinct patterns of internal moisture distribution throughout the tissue. Signal intensity variations suggest differential water content, with lighter regions indicating higher moisture concentrations. The tissue structure exhibits a network-like pattern with interconnected cellular regions. Patch morphology is characterized by irregularly shaped, variable-sized zones with contrasting signal intensities. These moisture-associated patterns provide insights into the spatial distribution of water within the apple's anatomical structure.
