Two of the body parts which do not appear in MRI are maybe

• A. Molar teeth and eye lens
• B. Scapula and canines
• C. Ligaments and ribs
• D. All of the above

When considering which body parts do not appear in an MRI, the correct answer is A. Molar teeth and eye lens. MRI scans are particularly effective for soft tissues, but they are less effective for dense structures like teeth and the eye lens, which are primarily composed of hard materials. Below is a brief overview of the options:

Options Explained

• A. Molar teeth and eye lens: These structures are dense and do not provide clear images in MRI scans.
• B. Scapula and canines: Both can be visualized in MRI, especially the scapula, which is a bone.
• C. Ligaments and ribs: Ligaments are soft tissues that can be seen in MRI, while ribs are bones that can also be imaged.
• D. All of the above: This option is incorrect as some of the mentioned parts can be visualized.

In summary, the best choice is A, as molar teeth and the eye lens are not effectively captured in MRI imaging.
