title: Problems in noninvasive imaging of pulmonary embolism.
abstract: The V/Q scintigram is the mainstay of pulmonary embolism diagnosis, but there are limitations, such as the need for sophisticated interpretation, the production of indeterminate readings, and the lack of specificity. The authors discuss these problems and the emerging techniques that may be more of a help to the radiologist faced with diagnosing pulmonary embolism.
