Clinical findings for six patients with discrepancies between clinical interpretation versus study interpretation

Study participant	D-dimer (µg/mL)	Wells score	Study radiologist's findings	Findings on ancillary studies	Location of embolism
48-year-old man	0.61	2.5	Indeterminate	Pulmonary angiography: negative	1 LLL subsegmental
70-year-old man (no treatment)	0.73	0	Indeterminate	None	1 at LUL posterior segmental–subsegmental junction
34-year-old woman	0.4	3	Negative	Pulmonary angiography and ultrasound of bilateral lower extremities: negative	1 at RUL proximal segmental junction; 1 at LLL proximal segmental junction <2 mm
71-year-old man (taking warfarin for atrial fibrillation)	0.70	6	Negative	None	1 at LUL anterior segmental-subsegmental junction
50-year-old woman (taking warfarin)	0.49	0	Negative	None	1 LLL distal subsegmental; 1 at LLL segmental-subsegmental junction
64-year-old man	0.64	3	Indeterminate	Pulmonary angiography: negative	1 at LLL distal segmental-subsegmental junction

LLL = left lower lobe; LUL = left upper lobe; RUL = right upper lobe.
