With the emergence of multidetector-row computed tomography (CT) it is now possible to
image both structure and function via use of a single imaging modality. Breath-hold spiral CT …

RATIONALE AND OBJECTIVES: To evaluate the adequacy of multibreath and single-breath
stable xenon gas techniques to measure regional ventilation during cardiac-gated, high …

Three pigs with surgically created aortopulmonary shunts and two pigs who had sham
operation were scanned in a fast computed tomography (CT) scanner, the dynamic spatial …

Lung disease is a leading cause of mortality in the United States. 2, 69 Chronic lung disease
encompasses a spectrum of diffuse lung diseases including emphysema, chronic bronchitis …

We have developed a method utilizing x-ray CT for relating pulmonary perfusion to global
and regional anatomy, allowing for detailed study of structure to function relationships. A …

Taking advantage of two scan modes of an electron beam CT scanner (Imatron), we have
developed a method utilizing x-ray CT for relating pulmonary perfusion to global and …
