Pulmonary Nodule Size Evaluation with Chest Tomosynthesis

Pulmonary nodule size evaluation with chest tomosynthesis and computed tomography: a phantom study

Detection of pulmonary nodules in chest tomosynthesis

Chest tomosynthesis is a relatively recently introduced technique in healthcare, which produces section images of the chest at a lower radiation dose than computed tomography (CT) and with better depth resolution than conventional chest radiography. The primary aims of the studies described in this dissertation were to compare chest tomosynthesis with conventional radiography, to evaluate the e...

X-ray Digital Tomosynthesis Imaging for Pulmonary Nodule Detection

Lung cancer is currently the primary cause of cancer death, and its incidence continues to increase worldwide. Because of its high sensitivity, normal-dose helical computed tomography (CT) is currently considered the gold standard for lung cancer detection. Previous studies have shown that low-dose helical CT can detect early-stage lung cancer, thereby decreasing morbidity (Yankelevitz et al., ...

Investigation of the effect of varying scatter-to-primary ratios on nodule contrast in chest tomosynthesis

The primary aim of the present work was to analyze the effects of varying scatter-to-primary ratios on the appearance of simulated nodules in chest tomosynthesis section images. Monte Carlo simulations of the chest tomosynthesis system GE Definium 8000 VolumeRAD (GE Healthcare, Chalfont St. Giles, UK) were used to investigate the variation of scatter-to-primary ratios between different angular ...

Pediatric pulmonary tuberculoma with a solid pulmonary nodule detected on chest computed tomography.

A 14-year-old girl underwent a medical checkup for Mycobacterium tuberculosis infection because her grandmother had been diagnosed with pulmonary tuberculosis three months earlier. The interferon-gamma release assay (IGRA) showed a positive result. The patient's chest X-ray findings were normal. Chest computed tomography (CT) showed a single mass lesion in the right lower lobe of the lung. A sp...
