ABSTRACT
Aim: To find out the added value of reformatted coronal thin sections of HRCT scans in diagnosis of lung diseases.
Methodology: Prospective study of 100 patients underwent CT chest with suspicion of lung disease. All scans were performed on 128 slice MDCT scanner. Two sets of lung images were made. Group 1 having 0.5 mm thick axial CT images Group 2 having 0.5 mm thick coronal images
Results: There was presence of abnormal lung infiltration in 48 cases in group 2 and same was in group 1. In identifying the CT features of lung disease between group 2 and group 1, there was no significant difference in both groups. In group 2, lung abnormalities in central, peripheral, anterior or posterior segments were better seen. Vertical dominance of lung changes was clearly evaluated in group 2 than in group 1.
Conclusion: Coronal reformats of CT scan shows lung disease more clearly as compared to axial sections.
Key words: Axial section, CT scan, Lung disease
