The Wells’ Criteria for Pulmonary Embolism objectifies risk of pulmonary embolism (PE).

Jul 18, 2024 · There are two principal approaches for performing a CTPA of high diagnostic quality: NB: This article is intended to outline some general principles of protocol design.

Jul 10, 2020 · In patients with low to intermediate clinical probability of PE, D-dimer should be the initial test. If negative, no treatment is indicated. If positive, computed tomographic pulmonary angiography (CTPA) should be performed for definitive diagnosis.

For the purposes of distinguishing between CT and CTA, ACR Appropriateness Criteria topics use the definition in the ACR–NASCI–SIR–SPR Practice Parameter for the Performance and Interpretation of Body Computed

Dec 1, 2017 · CTPA is the current gold standard in the diagnosis of acute PE with high accuracy, wide availability, and rapid turnaround time. Combining CTPA with clinical pre-test probability of PE yields superior sensitivity and specificity than imagining alone. VQ scanning is indicated in patients who are young, pregnant or cannot get contrast.

Oct 7, 2024 · ESC/ERS, NICE, and PERT recommend computed tomographic pulmonary angiography (CTPA) as first-line for acute PE diagnosis. ASH recommends using ventilation/perfusion (V/Q) lung scans over CTPA to reduce radiation exposure when this can be done rapidly and interpreted expertly.

Jun 13, 2019 · The Wells criteria for pulmonary embolism is a risk stratification score and clinical decision rule to estimate the probability for acute pulmonary embolism (PE) in patients in which history and examination suggests acute PE is a diagnostic possibility.

Each section of these guidelines is followed by recommendations, graded according to standard criteria.23The Appendix contains charts (with notes) designed to be modified,according to local consensus and facilities, for inclusion in hospital handbooks.

In people with suspected pulmonary embolism (PE), what is the diagnostic accuracy of the pulmonary embolism rule-out criteria (PERC)? The pulmonary embolism rule-out criteria (PERC) are a set of clinical criteria that have been designed to allow people with a low probability of pulmonary embolism (PE) to be discharged without further testing.

For people with a Wells score of more than 4 (PE likely) — arrange hospital admission for an immediate computed tomography pulmonary angiogram (CTPA) and, where necessary, other investigations.
