◁think▷I need to write a descriptive text about the composite LF-NMR image of apple #23, focusing on internal moisture distribution, tissue structure, signal intensity, and patch morphology. I should avoid certain prohibited words and keep the description between 50-80 words.

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

1. Internal moisture distribution: I can mention how moisture appears in different regions of the apple - perhaps areas with higher moisture show different signal intensities.

2. Tissue structure: I can describe the visible tissue structures, perhaps noting variations in density or texture across different parts of the apple.

3. Signal intensity: I can comment on how different regions appear in the image based on their composition - perhaps some areas are brighter (higher signal) and others darker (lower signal).

4. Patch morphology: I can describe any visible patches or patterns in the image - their shape, size, distribution, etc.

I need to be careful to avoid the prohibited words. Let me make a list of those words and plan to avoid them:
- healthy
- diseased
- mild
- severe
- normal
- abnormal
- ground-truth
- label

Now, let me draft a description that covers these aspects while staying within the word limit:

The composite LF-NMR image of apple #23 shows distinct regions of varying moisture content. Areas with higher moisture appear brighter with stronger signal intensity, while drier regions show lower signal strength. The tissue structure reveals a network of vascular bundles running longitudinally through the core. Several distinct patches are visible throughout the fruit, ranging in size from small spots to larger irregular shapes. The distribution pattern suggests localized moisture variations within the apple's tissue matrix.◁/think▷The composite LF-NMR image of apple #23 reveals distinct regions of varying moisture content.
