Thoracic helical CT.

Abstract

Helical CT depicts small pulmonary nodules not seen at conventional CT by elimination of respiratory misregistration and thorough analysis of a contiguous data volume. Pulmonary lesions can be analyzed in detail with use of retrospective reconstruction of the data volume. Multiplanar and three-dimensional images of lung masses and arteriovenous malformations are free of motion artifacts. The airways are clearly depicted by helical CT, a capability that enhances the radiologic evaluation of patients with hemoptysis, bronchial strictures, tumors, and recent lung transplantation. In comparison to conventional CT, helical CT provides a more consistent level of vascular enhancement because of the shortened acquisition time. Clinical applications include the detection of central pulmonary thromboemboli and the assessment of aortic aneurysms and dissections.

Trends in the use of diagnostic imaging in patients hospitalized with acute pulmonary embolism.

From 1979 to 2001, the proportion of imaging tests by computed tomography (CT), ventilation perfusion (VQ) lung scan, pulmonary angiography, and venous ultrasound was assessed in patients with pulmonary embolism (PE) from the National Hospital Discharge Survey. By 2001, there was a higher proportion of imaging tests with CT than VQ scans (36% vs 32%). Even so, in the United States, a large proportion of patients continued to have VQ scans.

[Berry syndrome: successful neonatal repair of a rare complex cardiac malformation].

Aortopulmonary septal defect, interrupted aortic arch, aortic origin of the right pulmonary artery, intact ventricular septum, and patent ductus arteriosus (Berry Syndrome) is a rarely reported malformation. A 6-day-old girl underwent successful one-stage complete repair of direct anastomosis between the ascending and descending aorta, reimplantation of the right pulmonary artery augmented with pericardium patch. Stenosis of the origin of the reimplanted right pulmonary artery was treated by balloon angioplasty at the age of 3 months. The authors emphasize the additive nature of surgical correction and interventional cardiology. Review of the literature reveals this patient to be the 25th reported case with Berry syndrome, and the first of that in Hungary.
