False left ventricular aneurysm with ventriculo-bronchial fistula and massive haemoptysis.

An intravenous drug user presented with bacteraemia and massive hemoptysis 10 years after a penetrating cardiac injury. He was found to have false left ventricular aneurysm with ventriculo-bronchial fistula. The clinical course suggests that the aneurysm became infected and that the inflammatory process weakened the aneurysmal sac and led to the development of fistula.

Three-dimensional computerized tomography: a quantum leap in diagnostic imaging?

Ever since the discovery of radium by Madame Curie, men and women of vision and science have labored to improve radiation technology. Over a period of approximately 85 years, we have gone from this initial discovery to three-dimensional computerized transmission tomography; one of the latest techniques in modern day x-ray imaging. Its uses are vast and unparalleled in many facets of medicine and surgery, outlining pathology as never before seen, and possibly, never before completely understood.

Neonatal magnification radiography using standard-focus x-ray tubes.

Radiographic examination of the chests of premature newborn infants is complicated by the small size and poor object contrast of the structures to be evaluated. Magnification radiography can improve image quality significantly in this situation. Unfortunately, high-quality magnification radiography requires dedicated microfocus equipment that is not available in most neonatal intensive care units.
