Brain scintigraphy with Tc99-pertechnetate in the evaluation of patients with cerebrovascular lesions. The diagnostic value related to age of the lesion and to the size, type and localisation revealed by CT-scan

摘要: ABSTRACT- Brain scintigraphy with Tc99-pertechnetate (Tc99-scan) was performed 4 times in 95 consecutive stroke patients: on average 5 days, 18 103 days and 194 after the stroke. The type (infarct, hematoma), size localisation of lesion evaluated by CT-scan 3 all: 207 stroke. The detection rate Tc99-scan 31 % day 5, 47 18, 9 194. however highly dependent upon: (i) lesion, i.e. superficially localised lesions were nearly always identified (90%) while infarcts deep hemisphere only 20 patients; (ii) large seen a much higher frequency than small infarcts. The practically not upon time investigation: 63% 3, 70% 69% 207. identical for 2–3 weeks In this period, however, 30 infarcts. Only 12 these Tc99-scan.
