“…Dual-energy computed tomography (DECT) is an emerging imaging technique that allows for collection of simultaneous absorption measurements at 2 energy levels, an approach that facilitates the separation of 2 materials within each imaged voxel, such as iodine and lung parenchyma. [19][20][21] Although at present primarily a research tool, the use of DECT to characterize the pulmonary vasculature has multiple potential clinical applications, particularly in the identification of perfusion deficits, and has been cross validated with other imaging strategies. 20,[22][23][24] Here, we performed DECT to quantify PBV in a multiethnic, multicenter, community-based sample of older adults.…”

“…5 Mit der technischen Weiterentwicklung sowie einigen weiteren Optimierungen konnten die ersten DSCT-Geräte Mitte der 2000er-Jahre in Betrieb genommen werden. 6,7 Im Zuge dieses technischen Fortschritts können seither mittels DSCT-Technologie unterschiedliche Materialkompositionen analysiert werden. 7,8 Hierbei wird unter anderem die quantitative Darstellung der Jodaufnahme verschiedener Strukturen in farbkodierten Bildern ermöglicht.…”

“…6,7 Im Zuge dieses technischen Fortschritts können seither mittels DSCT-Technologie unterschiedliche Materialkompositionen analysiert werden. 7,8 Hierbei wird unter anderem die quantitative Darstellung der Jodaufnahme verschiedener Strukturen in farbkodierten Bildern ermöglicht. 8 Substanzen mit einer niedrigen Anzahl an Atomen, beispielsweise Wasser, haben im Gegensatz zu Substanzen mit einer hohen Dichte an Atomen (Jod) nur geringe Unterschiede in der Abschwächung von hoch und niedrig dosierten Röntgenstrahlen.…”
