Computed Tomography (CT)

Computed tomography (CT) systems use a series of X-ray images to create an image volume dataset with slices that can be manipulated on any plane using advanced visualization software. The section includes computed tomography scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (dual-source CT), and iterative reconstruction dose reduction software.

Electronic cigarette or vaping product use-associated lung injury in a 51-year-old man manifesting as an acute lung injury pattern at CT with subsequent organization.

Electronic cigarette or vaping product use-associated lung injury in a 51-year-old man manifesting as an acute lung injury pattern at CT with subsequent organization. (a, c) Axial unenhanced CT images at presentation through (a) mid and (c) lower lungs show ground-glass opacity with subpleural sparing (arrows); this distribution was present in 45% of chest CT studies at presentation in our cohort (11). (b, d) Axial unenhanced CT images obtained 6 days later show ground-glass opacity has transitioned to consolidation and mild architectural distortion, consistent with developing organization. The patient was initially treated with antibiotics followed by corticosteroid therapy, with slow clinical improvement. Image courtesy of Radiological Society of North America

Researchers led by Göttingen University develop new three-dimensional imaging technique to visualize tissue damage in severe COVID-19

Sections through the three-dimensional reconstruction volume (upper left, grey) around a pulmonary alveolus with hyaline membrane (lower left, yellow). On the right, the images are superimposed. In the centre is the air bubble (alveolus). The electron density is represented by different shades of grey. On the inside of the air bubble is a layer of proteins and dead cell residues, the "hyaline membrane". This deposit, which can be represented in its three-dimensional structure for the first time by the new method, reduces the gas exchange and leads to respiratory distress.

Sheer stresses on the walls of arteries are believed to cause the formation atherosclerotic plaques. This is an area of research that is expected to see increased use in the next few years. This study was presented at SCCT 2020 as an example of how sheer stresses can help evaluate and predict the patency of coronary artery bypass grafts (CABG).
