在临床实践中,作者应用~(99m)Tc-HMPAO(六亚甲基胺肟)作脑灌注显像研究的病人已超过200例,包括脑血管意外,如中风、暂时缺血性发作、动脉畸形、血管痉挛、颈动脉狭窄和偏头痛等。另外,还进行了许多非脑血管意外情况的研究。 HMPAO可用于痴呆的鉴别诊断,早老性痴呆(Alheimer氏病)病人有对称的枕骨-顶骨缺损,可显示对称的特殊图形,而患多发性血管梗塞痴呆的病人则显示不对称的梗塞病灶。有正常压力的脑积液患者,有完整的皮质边缘,同时还有一个室周围的活性减少区。三
In clinical practice, the authors used ~ (99m) Tc-HMPAO (hexamethyleneamine oxime) as a brain perfusion imaging study in over 200 patients, including cerebrovascular accidents such as stroke, transient ischemic attack, arterial Deformity, vasospasm, carotid stenosis and migraine. In addition, there have been many non-cerebrovascular accidental studies. HMPAO can be used in the differential diagnosis of dementia. Patients with Alzheimer’s disease have symmetrical occipital-parietal defects with symmetrical special patterns, whereas patients with multiple vascular dementia show an asymmetric infarct. Patients with normal-pressure hydrocephalus have intact cortical edges, along with a zone of reduced activity around the chamber. three
