Application of spiral HRCT and the thin scan in the early diagnosis for acute lacunar infarction

Objective To investigate diagnostic value of spiral high resolution CT (HRCT) and open thin technology on early of lacunar cerebral infarction.Methods Retrospective analysis was carried out to 48 cases from August 2010 to May 2012 by MR and follow-up confirmed early of lacunar cerebral infarction with conventional spiral CT,spiral HRCT and open thin technology performance analysis,the focal size,CT value,the shape,position,number,appear time were all detected for comparative analysis.Cochran Armitage trend test was used for statistical analysis.Results The conventional spiral CT found 26 cases, spiral HRCT and open thin technology found 46 cases, the size of lesions with traditional spiral CT was 1-2 mm larger,CT value was lower(2-4 HU),edge was clear,position was accurate, number was bigger, and more time was earlier.Conclusion Spiral HRCT and open thin technology can improve the diagnosis for early CT of lacunar cerebral infarction. Key words: Spiral high-resolution CT and open thin technology; Early lacunar cerebral infarction
