Figs. 1.484, 1.485 (1.484) Ventrolateral 20° to dorsolateral oblique of the same area of the horse in 1.483.
This view allows the ipsilateral facet joints to be visualised very clearly (arrows). (1.485) The radiograph is
obtained using this oblique projection and the use of a cone. (Photo 1.485 courtesy Graham Munroe)

Fig. 1.486 Longitudinal ultrasound
image obtained on midline using a 13.3
MHz linear probe between T14 and T15.
The supraspinous ligament and Y-shaped
upper part of the interspinous region
can clearly be seen, but the interspinous
ligament appears black due to the
T14 T15
orientation of the fibres (see 1.477).
