Abstract
Pulmonary embolism (PE) is a common condition with considerable morbidity and mortality; it is more often diagnosed post-mortem by pathologists than in vivo by clinicians. Prompt and accurate diagnosis is difficult because PE may be clinically silent, the symptoms are vague and nonspecific, and in addition there is no definitive non-invasive diagnostic test to establish its diagnosis The advent of chest CT scanning for the diagnosis of PE was hailed as an improvement. By 2001, MSCT scanning of the chest was being used more often than V/Q scanning to investigate suspected PE and can image the entire chest with submillimeter resolution and requires a breath hold of less than 10 seconds.
