Characteristics of the manually outlined PE regions in the independent cohort and the high-confident PE regions in the RSNA-PE dataset

	Independent test set (n=91)	RSNA-PE (n=1,317)
Count: total, mean (SD), range	970, 10.66 (6.46), 1–30	4039, 3.07 (2.21), 1–9
Volume (ml): mean (SD)	0.74 (3.02)	1.08 (3.37)
*Cross-section radius (mm)^:** mean (SD)	1.82 (1.25)	2.06 (1.49)
Length (cm): mean (SD)	2.40 (3.50)	2.97 (3.84)
length (mm): count (%)
(0, 5)	169 (17.4%)	606 (15.0%)
[5, 10)	266 (27.4%)	820 (20.3%)
[10, 20)	235 (24.2%)	1,321 (32.7%)
[20, ∞)	300 (30.9%)	1,292 (32.0%)
Location: count (%)
Central (main artery) PE	193 (19.9%)	1,107 (27.4%)
right PE	419 (43.2%)	1,579 (39.1%)
left PE	358 (36.9%)	1,353 (33.5%)

The cross-section radius is the largest distance value of a suspicious PE region.
