Examples of study- and image-level labels. (a) Central Pulmonary
Embolism (PE): saddle embolus within the main, right, and left pulmonary
arteries (arrow). (b) Right-sided PE and Left-sided PE: pulmonary emboli
within the right interlobar, right lower lobe (arrow), and lingular
pulmonary arteries (arrowhead). (c) Chronic PE: nonocclusive intraluminal
web within the right lower lobe pulmonary artery (arrow). (d) True Filling
Defect not PE: left lung malignancy invading the left main pulmonary artery.
(e) Flow Artifact: an apparent filling defect within the left pulmonary
artery, which is due to laminar flow of contrast media rather than PE
(arrow). (f) RV/LV Ratio: < 1: normal RV (red line) to LV (blue line)
ratio. (g) RV/LV Ratio: ≥ 1: evidence of right heart strain
characterized by an elevated RV/LV ratio. (h) QA-motion: impaired image
quality at the lung bases due to respiratory motion (arrows). (i)
QA-contrast: insufficient opacification of the pulmonary arterial tree
(arrow) to allow for the assessment of PE. LV = left ventricle, QA
= quality assurance RV = right ventricle. — **Figure 1a:**

Study-level label schema. If a study had at least one image annotated
as PE Present on Image, the study had additional labels for location (one or
more), RV/LV ratio (only one), and type (only one, where Acute PE is assumed
if neither Chronic PE nor Acute and Chronic PE is annotated). Dashed lines
indicate implied study-level labels. Similarly, if the study was labeled as
Indeterminate, it was annotated with one or more quality assurance (QA)
labels. Note that True Filling Defect not PE and Flow Artifact are
informational labels only and not included in this diagram. LV = left
ventricle, PE = pulmonary embolism, RV = right
ventricle. — **Figure 2:**

system, PE = pulmonary embolism, RSNA = Radiological Society of North
