title: Acute pulmonary embolism.
abstract: CT pulmonary angiography has become a first-line imaging test for evaluation of PE because of its high accuracy, ease of use, and ready availability. PIOPED II supports the use of multidetector CT as a first-line test especially in outpatients. Technological advances continue to evolve, and with refinements in technology, we will continue to optimize imaging for PE detection. lonizing radiation remains a concern particularly in the young and in pregnant patients, and methods to decrease these are being advocated. SPECT V/Q may play a bigger role in PE diagnosis in the future and the role of MR is yet to be determined in the PIOPED ll study, with the potential of solving some of the issues regarding radiation in a select group of patients.
