Abstract

This case study describes the magnetic resonance characteristics of brain infarction in three dogs. Locations of the brain infarcts were cerebella, thalamus, and multifocal. The infarcts were sharply demarcated from adjacent brain parenchyma, homogeneous, T1-hypointense, T2-hyperintense with/without contrast enhancement, and minimal or no mass effect. Diffusion-weighted imaging (DWI) sequences were available in a dog and the infarcts were hyperintense on DWI and were hypointense on the apparent diffusion coefficient map.

뇌경색으로 진단한 소형견 3 마리의 자기공명영상 (MRI)을 평가하였다. 뇌경색은 소뇌, 시상, 혹은 다발성으로 발생하였다. 뇌경색은 병변의 경계가 비교적 뚜렷하고, 균질하게 T1강조영상에서 저신호, T2강조영상에서 고신호를 나타내었다. 조영증강효과는 없거나, 병변의 주변부로 미약하게 조영증강효과가 나타나기도 했다. 확산강조영상 (DWI)에서는 고신호로 나타나며 이 부위의 겉보기확산계수 (ADC)는 감소되었다.
