Planar ventilation–perfusion (V/Q) scanning is often used to investigate pulmonary
embolism; however, it has well-recognized limitations. SPECT overcomes many of these …

The prone posture is known to have numerous effects on gas exchange, both under normal
conditions and in patients with ARDS. Clinical studies have consistently demonstrated …

The charge of this Joint ATS/ERS Task Force was to critically review the state-of-the-art
stereological methods in lung morphometry, provide practical guidelines for use of these …

OBJECTIVE. The purpose of this study was to assess the feasibility and diagnostic value of
dual-energy CT iodine mapping at pulmonary CT angiography. SUBJECTS AND …

Two calculation methods to produce ventilation images from four-dimensional computed
tomography (4DCT) acquired without added contrast have been reported. We reported a …

OBJECTIVE: Aims were (1) to determine the diagnostic accuracy of Dual Energy CT (DECT)

Acute pulmonary embolism causes redistribution of blood in the lung, which impairs
ventilation/perfusion matching and gas exchange and can elevate pulmonary arterial …

Background and purpose Radiotherapy that selectively avoids irradiating highly-functional
lung regions may reduce pulmonary toxicity. We report on the first clinical implementation …

Purpose 4-dimensional computed tomography (4D-CT)-based pulmonary ventilation
imaging is an emerging functional imaging modality. The purpose of this study was to …
