Fig. 1

Axial T2-weighted fat-suppressed MR images of five patients without head and neck cancer with normal/benign reactive nodes in the less documented nodal groups in the upper head and neck, comprising parotid (a), submandibular (b), occipital (c), Level IIb (d) and retroauricular nodes (e). The mean SADs of the largest nodes for parotid, submandibular, occipital, Level IIb, and retroauricular nodes were 4.4 ± 1.0 mm, 5.5 ± 1.4 mm, 3.8 ± 1.0 mm, 4.3 ± 1.2 mm, and 3.8 ± 0.7 mm, respectively. (PG = parotid gland, SMG = submandibular gland, EAC = external auditory canal, SAD = short axis diameter, 1 = Splenius capitis muscle, 2 = sternocleidomastoid muscle, 3 = trapezius muscle, 4 = occipital subcutaneous fat)
