Aortic Pathology in Patients With Bicuspid Aortic Valve Assessed With Computed Tomography Angiography by Michalowska IM et al.
This study of 102 patients with bicuspid aortic valve (BAV) shows that BAV with raphe is more common than true BAV and that raphe is more commonly associated with aortic dilation and aneurysm whereas true BAV is more commonly associated with aortic coarctation.
Dual-energy Computed Tomography in the Assessment of Vascular and Parenchymal Enhancement in Suspected Pulmonary Hypertension by
In this study of patients who underwent dual energy CT (DECT) of the chest, 89 patients with pulmonary artery pressure measurements and pulmonary angiogram were identified. CTs were analyzed for pulmonary artery enhancement, volumetric whole lung enhancement, and various lung regions of interest. The authors conclude that in patients with pulmonary hypertension, pulmonary artery enhancement is higher with reciprocal decrease in pulmonary parenchymal enhancement with more heterogeneity.
Image Quality and Feasibility of an Ultralow-dose High-pitch Helical Triple-rule-out Computed Tomography Angiography Acquired in the Caudocranial Direction by Kligerman SJ and White CS.
In this study, 10 men were imaged with low-dose, high-pitch helical CT angiography on a second-generation dual source scanner using a “triple rule-out” protocol. Image quality was assessed by two cardiothoracic radiologists, who scored only 3.9% of regions as being moderately limited for assessment. The mean effective dose across the study is 1.39 mSv.
