Early Signs Of CT In The Diagnosis Of Malignant Middle Cerebral Artery Infarction Of The Clinical Significance

Purpose: To study the clinical significance of early signs of CT in thediagnosis of malignant middle cerebral artery infarction.Methods: 4-row helical scanning machines suspected of newlydiagnosed malignant middle cerebral artery infarction in 60 patients, CTThe first CT scan time of onset within 6 hours and the second time to scanthe incidence 24-72 hour period, Clinical signs light positioning indicatorscarefully read films, analysis of early CT signs in all its manifestations.Results: 60 patients were different manifestations of early CT signs.Hyperdense middle cerebral artery sign 38 cases, the sensitivity of 63.3ï¼…,specificity of diagnosis of 92.1ï¼…. Edge unclear brain low density sign 51cases, the sensitivity of 85ï¼…, specificity of diagnosis of 94.1ï¼…. Localswelling sign 26 cases, the sensitivity of 43.3ï¼…, specificity of 100ï¼…diagnosis.Conclusions: 1. CT appearance of early HMCAS, edge unclear brainlevy higher density diagnostic specificity, malignant middle cerebral arteryinfarction with high diagnostic imaging value. 2. Early CT signs canshorten the time of clinical diagnosis and raise the diagnosis rate. 3. EarlyCT signs provide a basis of a coincidence Optional for thrombolytictherapy adapt and guarantee their safeties.
