MAGNETIC RESONANCE IMAGING OF BRAIN INFARCTION IN SEVEN DOGS

Abstract

Magnetic resonance imaging was performed in seven dogs with histopathologically‐confirmed brain infarcts. The infarcts were non‐hemorrhagic in four dogs and hemorrhagic in three dogs. Six dogs had single infarcts involving the cerebrum and one dog had multiple infarcts involving the cerebrum and brain stem. Non‐hemorrhagic infarcts were typically wedge‐shaped, hypointense on T1‐weighted images, hyperintense on T2‐weighted images, and did not enhance with gadolinium‐DTPA. Hemorrhagic infarcts had mixed intensity on T1‐ and T2‐weighted images, with variable patterns of enhancement.
