Figure 21.7 Sagittal (A) proton

density MR image and (B)

transverse SE T1-weighted MR

image of a 2-year-old, male

Great Dane, depicting some

normal anatomic structures. The

caudal aspect of the joint capsule

and synovium (black arrow) is

seen between the joint space and

gastrocnemius muscle. For key to

labels, see Table 21.1.

Figure 21.8 Dorsal (A) and

transverse (B) SE T1-weighted

(TR860/TE26) MR images of a

2-year-old, neutered female

Chesapeake Bay Retriever,

depicting some normal anatomic

structures. The transverse scan is

obtained through both menisci:

the menisci (arrows) appear as

apposing crescents with

heterogeneous low SI due to

slice thickness artifacts. For key

to labels, see Table 21.1.

Figure 21.9 Schematic transverse section through the thigh (A) and crus (B) depicting the anatomic relationship of
muscles and bones. The positional relationship of the supporting musculature is important when assessing joints. For key
