The correct answer is: scapula and canines
MRI is a non-invasive technique which uses strong magnetic field for generating resonance and low radio frequency in protons present in body. Most common protons are $\mathrm{H}$ nuclei of $\mathrm{H}_2 \mathrm{O}$ molecules. Scapula and canine are osteocytic structures with negligible $\mathrm{H}_2 \mathrm{O}$ content.
