Figure 4.15 Transverse plane T2‐weighted MRI (A) and postcontrast CT (B) of a dog with a small lacunar infarct (arrow in A) within the rostroventral part
of the left caudate nucleus and adjacent white matter. The lesion is clearly seen on MRI but is not visible on the CT image. CT is relatively insensitive
for detection of small infarcts, and metabolic and inflammatory disease.
