◁think▷I need to write a 50–80 word English description of the provided LF-NMR image of apple #98, focusing on internal moisture distribution, tissue structure, signal intensity, and patch morphology. I should avoid using certain prohibited words and not include any JSON, Chinese, or extra explanations.

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

1. Internal moisture distribution: The image shows grayscale variations that likely represent different moisture levels within the apple. Darker areas might indicate higher moisture content, while lighter areas could indicate drier regions.

2. Tissue structure: The overall structure appears to have a somewhat heterogeneous texture, with variations in graininess and smoothness across different regions of the apple.

3. Signal intensity: In LF-NMR imaging, signal intensity typically correlates with water content. The image shows varying shades of gray, suggesting spatially varying signal intensities corresponding to different moisture levels.

4. Patch morphology: There appear to be some distinct patches or regions with different morphologies. Some areas look more uniform, while others have slightly irregular boundaries and variations in texture.

Now I'll craft a description that covers these aspects without using the prohibited words. I'll focus on objective observations about the image content:

- I'll describe the overall appearance and variations
- I'll mention the grayscale representation of moisture
- I'll note the tissue structure variations
- I'll describe the signal intensity variations
- I'll mention the patch morphology observations

I need to be careful to avoid words like "healthy", "diseased", "mild", "severe", "normal", "abnormal", "ground-truth", or "label".

Let me draft the description:◁/think▷The composite LF-NMR image of apple #98 displays distinct grayscale variations representing internal moisture distribution. Tissue structure exhibits heterogeneous texture with subtle graininess and smoothness differences across regions. Signal intensity shows spatially varying shades corresponding to moisture content, with darker areas indicating higher water content. Patch morphology reveals several distinct regions with irregular boundaries and slight variations in texture patterns. The overall appearance demonstrates characteristic variations in both signal intensity and tissue structure throughout the apple's cross-sectional view.
