Perfusion scans were obtained in all patients and ventilation scans in almost all, using standardized techniques. Chest radiographs were obtained in all patients within 12 hr of the lung scan. Most patients underwent pulmonary arteriography. The images were interpreted according to a set of interpretive criteria which remained constant throughout the trial. A standardized, detailed description of each image set was derived by consensus of teams of two readers blinded to clinical and arteriographic findings. This communication reports the methods used to describe and categorize the ventilation-perfusion scintigrams obtained in patients who were enrolled in the PIOPED study.

In current clinical practice lung scintigraphy is mainly used to exclude pulmonary embolism (PE). Modified diagnostic criteria for planar lung scintigraphy are considered, as newer scitigraphic methods, especially single photon emission computed tomography (SPECT) are becoming more popular. Patients and methods. Data of 98 outpatients who underwent planar ventilation/perfusion (V/Q) scintigraphy and 49 outpatients who underwent V/Q SPECT from the emergency department (ED) were retrospectively collected. Planar V/Q images were interpreted according to 0.5 segment mismatch criteria and revised PIOPED II criteria and perfusion scans according to PISA-PED criteria. V/Q SPECT images were interpreted according to the criteria suggested in EANM guidelines. Final diagnosis of PE was based on the clinical decision of an attending physician and evaluation of a 12 months follow-up period. Results. Using 0.5 segment mismatch criteria and revised PIOPED II, planar V/Q scans were diag...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Lung scintigraphy in the diagnosis of pulmonary embolism: current methods and interpretation criteria in clinical practice","attachmentId":70749567,"attachmentType":"pdf","work_url":"https://www.academia.edu/54335524/Lung_scintigraphy_in_the_diagnosis_of_pulmonary_embolism_current_methods_and_interpretation_criteria_in_clinical_practice","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/54335524/Lung_scintigraphy_in_the_diagnosis_of_pulmonary_embolism_current_methods_and_interpretation_criteria_in_clinical_practice"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="3" data-entity-id="107762448" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/107762448/Ventilation_perfusion_scintigraphy_in_the_PIOPED_study_Part_II_Evaluation_of_the_scintigraphic_criteria_and_interpretations">Ventilation-perfusion scintigraphy in the PIOPED study.

In addition, the correlation of percent probability estimates with the actual frequency of pulmonary embolism (PE) is presented. Cases which met the PIOPED criteria for various diagnostic categories were selected by computerized search of the detailed scan descriptions that had been done as part of the study. The process by which the scans were described was detailed in Part I of this report. Most of the criteria appropriately categorized V/Q scans which satisfied them. However, we recommend that three criteria should be reconsidered: 1. A single moderate perfusion defect is appropriately categorized as intermediate, rather than as low probability. 2. Extensive matched V/Q abnormalities are appropriate for low probability, provided that the chest radiograph is clear. On the other hand, single-matched defects may be better categorized as intermediate probability. Although due to the small number of cases with this finding, no definite, statistically founded recommendation can be made. 3. Two segmental mismatches may not be the optimum threshold for high probability, and in some cases should be considered for intermediate probability. However, due to the small number of cases with this finding, no definite, statistically founded recommendation can be made. We suggest that the revised criteria resulting from these adjustments should now be used for the interpretation of V/Q scans.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Ventilation-perfusion scintigraphy in the PIOPED study.

Ventilation-perfusion (V/Q) scintigraphy is widely used as the first step in diagnosing PE since it is non-invasive and highly sensitive. With a normal perfusion scan, clinically relevant pulmonary thrombo-emboli are considered to be absent. In an ongoing study assessing the value of spiral CT in the diagnosis of PE, we encountered a patient who had a normal perfusion scan while a large partially occluding thrombus in the right lower lobe artery and its branches was depicted by spiral CT and pulmonary angiography. In this article, we discuss the significance of normal findings in perfusion scintigraphy, the causes of false-negative perfusion scans and the role of alternative techniques such as spiral CT and pulmonary angiography.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Normal perfusion scintigraphy in pulmonary embolism.

Furthermore, the reporting criteria used for interpretation of both planar and SPECT V/Q scans are variable and data are lacking regarding which criteria are commonly used in various centers. The aim of this study was to assess current practices regarding the performance and interpretation of lung scintigraphy across 3 different countries. A short on-line survey comprised of simple multiple-choice questions was distributed to nuclear medicine departments in Australia, Canada and France during the period April to December 2014. The survey covered image acquisition, interpretation criteria for SPECT and planar images, use of pseudo-planar images and radiopharmaceuticals.

Data from the PIOPED frequent user tape and journal articles published between 1990 and 1994 and indexed on Medline that presented data from the PIOPED study were reviewed. A normal V/Q lung scan excludes the diagnosis of clinically significant PE. The usefulness of the V/Q lung scan was optimized when interpreted as representing a very low, low or high probability of PE with a concordant clinical likelihood of PE. Patients with a V/Q lung scan interpreted as representing an intermediate probability of PE or patients with discordant clinical likelihood of PE and lung scan interpretation will often require further investigations to diagnose or exclude acu...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Comprehensive analysis of the results of the PIOPED Study.

We examined whether this function of the ventilation scan could be replaced by the chest X-ray. In 389 consecutive patients with suspected pulmonary embolism and at least one segmental perfusion defect we classified the ventilation/perfusion (V/Q) scan and chest X-ray/perfusion (X/Q) scan as either mismatched or matched. Furthermore we analyzed whether this comparison was different in subgroups of patients with concomitant congestive heart failure or chronic obstructive pulmonary disease. Overall agreement between the X/Q and V/Q scan diagnostic category was found in 341 of 389 patients (88%; 95% CI 84-92%).
