Background Computed tomography (CT) pulmonary angiography has simplified the
diagnostic approach to patients with clinically suspected acute pulmonary embolism (PE) …

Lung scintigraphy, or ventilation-perfusion (V/Q) scan, is one of the commonly performed
studies in nuclear medicine. Owing to variability in clinical applications and different …

Purpose Our purpose was to develop a deep learning–based computed tomography (CT)
perfusion mapping (DL-CTPM) method that synthesizes lung perfusion images from CT …

Regional pulmonary perfusion (Q) has been investigated using blood volume (Fb) imaging
as an easier-to-measure surrogate. However, it is unclear if changing pulmonary conditions …

Background Iodine material images (aka iodine basis images) generated from dual energy
computed tomography (DECT) have been used to assess potential perfusion defects in the …

Purpose There is an increasing interest in the evaluation of lung function from physiological
images in radiation therapy treatment planning to reduce the extent of postradiation …

Radiotherapy plays an irreplaceable and unique role in treating thoracic tumors, but the
occurrence of radiation-induced lung injury limited the increase in tumor target doses and …

Objective: The effect of functional lung avoidance planning on radiation dose-dependent
changes in regional lung perfusion is unknown. We characterized dose-perfusion response …

Purpose Previous studies have shown that the red cell index (RCI) can be considered as a
simple and useful method to evaluate respiratory function. However, at present its …

Background In this study, we aimed to identify a simple method for evaluating respiratory
function using complete blood count parameters. Methods The complete blood count …
