Abstract
Objective To investigate the application of dual- source four- dimensional CT angiography (4D- CTA) com-bined with CT perfusion imaging (CTPI) in diagnosis of acute cerebral ischemic diseases. Methods Thirty patients with clinical y suspected acute cerebral ischemic disease underwent head plain CT scan and whole brain CTPI examination 2~16h after onset, the images of CBF, CBV, MTT, TTP and 4D- CTA were obtained. Patients also underwent MRI examination in 1~3 d. The findings of plain CT scan, CTPI, 4D- CTA and MRI were analyzed. Results Plain CT scan found 16 ischemic lesions in 12 cases, CTPI found 32 ischemic lesions in 26 cases, MRI found 28 ischemic lesions in 25 cases, and 4D- CTA demonstrated various degree of stenosis or occlusion in supplying vessels in 20 cases. Conclusion Dual- source 4D- CTA combined with CT perfusion imaging provides comprehensive and detailed imaging information, so that has important value for early diagnosis and treatment in pa-tients with acute cerebral ischemia.关键词
