PURPOSE: To date, the high spatial frequency algorithm (HSFA) which reduces image smoothing and increases spatial resolution has been used for the evaluation of parenchymal lung diseases in thin-section high-resolution CT. In this study, we compared the ultrahigh spatial frequency algorithm (UHSFA) with the high spatial frequency algorithm in the assessment of thin section images of the lung parenchyma. METHODS AND MATERIALS: Three radiologists compared the UHSFA and HSFA on identical CT images in a line-pair resolution phantom, one lung specimen, 2 patients with normal lung and 18 patients with abnormal lung parenchyma. RESULTS: Scanning of a line-pair resolution phantom demonstrated no difference in resolution between two techniques but it showed that outer lines of the line pairs with maximal resolution looked thicker on UHSFA than those on HSFA. Lung parenchymal detail with UHSFA was judged equal or superior to HSFA in 95% of images. Lung parenchymal sharpness was improved with UHSFA in all images. Although UHSFA resulted in an increase in visible noise, observers did not found that image noise interfered with image interpretation. The visual CT attenuation of normal lung parenchyma is minimally increased in images with HSFA. The overall visual preference of the images reconstructed on UHSFA was considered equal to or greater than that of those reconstructed on HSFA in 78% of images. CONCLUSION: The ultrahigh spatial frequency algorithm improved the overall visual quality of the images in pulmonary parenchymal high-resolution CT.

In general, a bulla of the lung is large, air contained sac and it is more than 1cm in diameter, and its wall is well defined and less than 2mm thick. The natural course of bulla of the lung is said to follow a pattern of progressive deterioration. It is a progressive disease, and spontaneous resolution of bulla is very unusual. In the world only two cases of spontaneous resolution of bulla have been reported. We experienced a case of bullous lung disease complicated from miliary tuberculosis in which the bulla was disappeared spontaneously following bulla infection.

173 patients admitted to the Respiratory Department of Bach Mai Hospital between 12/2000 to 7/2001 were underwent flexible bronchoscopy. The results showed that the rate of bronchial cancer was highest (57.8%). Among that, the rate of central bronchial cancer was 87% and the rate of periperal bronchial cancer was 13%. Lung tuberculosis was 8.1% and chronic bronchitis is 9.8%. Bronchoscopy was useful in diagnosing some other conditions such as asthma, sarcoidosis, laryngoptosis etc. Bronchoscopy combined with bronchial fluid aspiration produced high diagnostic value in bronchial tuberculosis. Rate of smokers in bronchial cancer patients was 60%. The higher level of smoking, the more likely to be suffered from lung cancer.
