Type of imaging | Reason for examination | Outcome | Suggested practice by included study/studies | References |
---|---|---|---|---|
Chest CTA | Pulmonary embolism | 3% relevant findings | Â | |
Follow-up abdominal aorta CTA | Post EVAR | 3.6% relevant findings | Reduce the number of follow-ups in patients with normal CTA with no endoleak 1Â month after EVAR | |
Use doppler US as surveillance unless patient has symptoms or abnormalities on first follow-up | [224] | |||
Spine CTA | Blunt vertebral artery injuries | No relevant findings | Â | [225] |
Lower extremity CTA | Lower extremity vascular injuries | 40% relevant findings | Use CTA only in patients with high clinical suspicion and absence of hard signs | [226] |
Routine Compression US | Deep venous thrombosis in patients with Lower Extremity Cellulitis | 8% relevant findings | Â | [217] |
Routine lower extremity veins US | Asymptomatic leg in patients with deep venous thrombosis | 0–0.8% relevant findings |  | [218] |
Deep venous thrombosis | No relevant findings | Use a D-dimer test together with a Wells score risk factors as screening | [219] | |
Post-op lower extremity veins US | Deep venous thrombosis | No relevant findings | US pre-op only | [220] |
Four extremity vein duplex US | Deep venous thrombosis | 7.5% relevant findings | Â | [221] |
