Figure 1.

Anterior maximum intensity projection image (a) of 68Ga-prostate-specific membrane antigen positron emission tomography–computed tomography shows absent submandibular salivary gland on the right side as well as prominence of the contralateral one. The absent gland is better depicted on 68Ga-prostate-specific membrane antigen positron emission tomography (b), computed tomography (c), and fused positron emission tomography–computed tomography image (d)
