CT pulmonary angiogram compared with ventilation-perfusion scan for the diagnosis of pulmonary embolism in patients with cardiorespiratory disease.
A short cut review was carried out to establish whether VQ scanning has better utility than CT in investigating possible pulmonary embolus in patients with chronic respiratory disease. A total of 239 papers were found using the reported search, of which one presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of this best paper are tabulated. A clinical bottom line is stated.
