OBJECTIVE. The purpose of this article is to illustrate the spectrum of central airway and vascular complications in lung transplantation using MDCT, with an emphasis on the usefulness of advanced postprocessing techniques. CONCLUSION. MDCT is an invaluable tool in the diagnosis, evaluation, and posttreatment assessment of central airway and vascular complic […]
OBJECTIVE. The imaging of pulmonary nodules is an evolving and dynamic field. In this review, we discuss the detection and multitechnique characterization of pulmonary nodules, emphasizing the impact of technological advances on both noninvasive and invasive evaluation and surveillance. The potential contribution of MRI, evolving imaging-guided techniques, a […]
OBJECTIVE. The purpose of this study was to determine the effectiveness of a 3D adaptive raw-data filter in improving image quality and the role of the filter in radiation dose reduction in lung CT. MATERIALS AND METHODS. Fifty-eight chest CT examinations were performed with a 16-MDCT scanner. Two acquisitions were performed with different tube current […]
OBJECTIVE. The use of thrombolytic agents and other forms of reperfusion therapy has provided a means to reverse ischemia and minimize the size of infarctions. The purpose of this review is to examine various clinical trials of reperfusion agents and address key imaging issues. CONCLUSION. Advanced MRI and CT play a growing role in selection of patients for […]
