Measurement diagram of cervical longus, cervical extensor muscles, vertebral body area, and ratio of long and short diameter line (RLS) of cervical longus in axial position. A. cervical longus; B. multifidus muscle + semispinalis cervicalis muscle; C. splenius cervicis muscle + musculus semispinalis capitis; D. splenius capitis. The long (L) and short (S) lines must be intersected in the closed figure of the cross section and perform “dichotomy cutting” on the closed figure. RLS = L/S
