Computed Tomography (CT)

Through computed tomography (CT) imaging, WVU geologist James Lamsdell led a team that found evidence of air breathing in a 340 million-year-old sea scorpion, or eurypterid. This is one of the scans of the specimen. Image courtesy of James Lamsdell

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

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.

During the SCCT 2020 virtual meeting, SCCT President Ron Blankstein, M.D., Brigham and Women's, presented the SCCT Gold Award to John Lesser, M.D., MSCCT, director of advanced imaging and cardiac CT, Minneapolis Heart Institute, Abbott Northwestern Hospital.
