Plain-English summary
In this study, two dogs and a cat were examined for problems in their brains using two types of imaging: computed tomography (CT) and magnetic resonance (MR) imaging. One dog had vestibular syndrome, and MR imaging provided clearer pictures of the brain area affected because CT images were not as clear due to interference from surrounding bones. Another dog had brain tumors from lymphoma, and CT was better at showing the tumors than MR, especially since the dog had received a medication called dexamethasone to reduce swelling in the brain just before the MR scan. The cat had a condition related to lymphocytic leukemia, and only MR imaging was able to show the size and location of the problem. Overall, the findings suggest that the choice between CT and MR imaging should depend on the specific type and location of the brain issue being investigated.
Abstract
Two dogs and a cat with intracranial lesions were evaluated by both computed tomography (CT) and magnetic resonance (MR) imaging. In a dog with vestibular syndrome, better quality images of the medulla oblongata surrounded by thick bones were obtained by MR than by CT, on which the appearance of artifacts impeded the clear image of the area. In a dog with multiple brain metastases of lymphoma, contrast CT delineated lesions more clearly than MR, which was performed one week after CT. During that week dexamethasone which might affect the clarity of MR images of the lesion was administered to reduce brain edema. In a cat with meningeal syndrome of lymphocytic leukemia, only contrast MR imaging identified the width and site of the lesion. These results indicate that it is necessary to select either one of these imaging methods according to the type and site of lesions that are suspected in a particular case.
