Abstract: The release of modern dual-energy CT (DECT) scanners has allowed comparison content to be recognized at imaging without the need for an individual unenhanced scan. Images of lung parenchymal comparison improvement acquired using DECT improve the recognition of problems, boosting our ability to identify lung perfusion; however, with these developments new problems are also presented. In this graphic evaluation, we present the strategy, medical programs and causes and solutions of incorrect results of dual-energy lung parenchymal improvement problems in lung perfusion.
Objective: To evaluate the feasibility and findings of combined dual-energy computed tomography (DECT) lung ventilation/perfusion imaging in patients with congenital heart disease. And to assess perfusion patterns on a dual-energy pulmonary CT angiography.
Material and Methods: In this study Medline (pubmed) literature review and analysis for previous studies that are discussing, roles of dual-energy CT (DECT) scanners in the daily practice such lung perfusion scans and the including criteria were involving for several randomized studies that concerning patients suffering from congenital heart diseases from different ages which different perfusion patterns.
Results: DECT lung perfusion. Normal pulmonary BFI images were defined as showing homogeneous perfusion in the normal range (color-coded yellow-green or blue) with dependent symmetric lung iodine distribution. Dependent lung perfusion at DECT refers to relatively low contrast enhancement in the central regions
Conclusion: Quantitative LPS is simple, safe and widely available. Several patterns of LPS are seen in patients with CHD. But the DECT method may be considered as an alternative test in some patients due to the accuracy of performing results.
Keywords: modern dual-energy, using DECT, dual-energy.
