Abstract
BackgroundEarly detection of infarction is important for early management to minimize the effects of infarctions on the patient. Hyperdense middle cerebral artery is an early sign for infarction. ObjectivesTo determine the most accurate way and value for early detection of infarction using hyperdense MCA artery sign. Patients & method87 patients with suspected infarction underwent non enhanced CT brain, hyperdense MCA was subjectively determined, then maximum density was determined in the suspected affected side and contralateral side and ratio was made then, follow-up CT was done to detect MCA territory infarction. ResultsThe HU range of the affected MCA ranged from 44 up to 58 HU (mean value 49.62 HU). The mean value of MCA ratio was 1.24–1.55. HU value >47 and MCA ratio >1.5 100% sensitivity is compared to subjective method that gives 56.3% only. The objective measurements of the MCA as regards HU value and MCA ratio had a sensitivity of 100%, and specificity 60%. ConclusionHyperdense middle cerebral artery sign is an accurate method for early detection of infarction.
