CT and pathological study on radiofrequency-induced lesion in cat thalamus.
In order to observe the postoperative focal changes caused by radiofrequency lesions in the ventrolateral nucleus of the thalamus in stereotactic treatment of Parkinson's disease, similar lesions were produced in cat. The CT features and their correlative pathologic changes at different intervals were divided into three types, four stages and three zones. The degree of susceptibility of nervous tissue to radiofrequency, repair characteristics and the mechanism of CT enhancement are discussed in light of the pathologic changes.
