Empirical description of bronchial and nonbronchial arteries with MDCT

Pulmonary malignant focal ground-glass opacity nodules and solid nodules of 3 cm or less: Comparison of multi-detector CT features

“…Arterial phase and delayed phase images were acquired, 20-25 s and 90 s after injection, respectively. 11 The following imaging parameters were used: mA 250, kVp 120, collimation 1 mm, pitch 0.98, filtration coefficient 52 or 1(high or standard resolution algorithm).…”

Morphological Analysis of Bronchial Arteries and Variants with Computed Tomography Angiography

“…Other studies have described the origin of the bronchial arteries, without reporting its full pattern, which limits the analysis of the results [14, 17, 18]. Other variables have been evaluated by computed tomography, such as ostium of the bronchial arteries in the aorta [23], the vertebral levels origin [14, 15, 18, 24], path through the posterior mediastinum [18], and diameter [14, 19, 25, 26]. To our knowledge, there are no studies that evaluate all of these variables in the same population.…”

Preprocedural Planning with Prospectively Triggered Multidetector Row CT Angiography Prior to Bronchial Artery Embolization in Cystic Fibrosis Patients with Massive Hemoptysis

“…With advancements in CT imaging of the chest, thoracic radiology is a viable option in defining the bronchial circulation in patients with hemoptysis [6][7][8][9][10][11]. In a cohort of 46 patients in whom a 4-or 16-detector row was used, investigators found that multidetector row helical CT angiography of the thorax with three-dimensional images was superior to transverse CT scans in depicting the ectopic origin of the bronchial arteries.…”

“…Fiber-optic bronchoscopy has been used as a diagnostic tool to identify the site of bleeding, but the timing remains controversial [4,5]. However, there is growing evidence that multidetector row CT angiography of the chest is useful in identifying bleeding bronchial arteries [6][7][8][9][10][11]. Therefore, this study evaluated the usefulness of electrocardiographically synchronized, prospectively triggered multidetector row CT (ECG-MDR-CT) angiography of the aorta in depicting bronchial artery anatomy in adult CF patients with refractory massive hemoptysis in preparation for BAE.…”
