Diagnostic Accuracy of Dynamic Contrast Enhanced Magnetic Resonance Imaging in Characterizing Lung Masses.

Background: Imaging plays a critical role not only in the detection, but also in the characterization of lung masses as benign or malignant.

Objectives: To determine the diagnostic accuracy of dynamic magnetic resonance imaging (MRI) in the differential diagnosis of benign and malignant lung masses.

Patients And Methods: Ninety-four masses were included in this prospective study.

Crossed pulmonary arteries: a report on 20 cases with an emphasis on the clinical features and the genetic and cardiac abnormalities.

Crossed pulmonary arteries (CPAs) are a rare abnormality in which the ostium of the left pulmonary artery originates superior to the right pulmonary artery and to its right. Recognition of this rare pathology is important because it generally is accompanied by other congenital heart defects, extracardiac anomalies, and certain genetic problems. To date, only a few cases have been reported, and most of these cases have been associated with complex cardiac abnormalities.

Echocardiographic and three-dimensional computed tomographic diagnosis of crossed pulmonary arteries: report of three cases.

Crossed pulmonary arteries are rare anomalies of the pulmonary trunk and its branches. In this anomaly, the ostium of the left pulmonary artery originates superiorly and to the right of the right pulmonary artery. This anomaly is usually associated with other congenital cardiac and extracardiac diseases.
