Contrast-enhanced Ultrasound Instead of CTA in EVAR-surveillance

Contrast-enhanced endoscopic ultrasound.

Compared to other imaging modalities, endoscopic ultrasound (EUS) has limitations in terms of image enhancement. However, with the availability of contrast agents in ultrasonography, EUS has evolved. Contrast-enhanced Doppler EUS (CD-EUS) enhances Doppler signals from vessels and is useful for characterizing lesions detected by EUS. Moreover, contrast-enhanced harmonic EUS (CH-EUS) with second-...

Contrast-enhanced ultrasound in oncology

In patients with known malignant disease, 51% of liver lesions less than 1.5 cm turn out to be benign. Whether the probability of malignancy is high or low, further investigations are often necessary to definitely exclude malignancy. Contrast-enhanced ultrasonography has a prominent role in lesion characterization with a diagnostic accuracy comparable with computed tomography and magnetic reson...

Simplifying post-EVAR surveillance.

Surveillance after endovascular aneurysm repair (EVAR) is costly and a burden for the patient. Imaging is performed to detect stent-graft failure from endoleak or haemodynamic obstruction. Presently, computed tomographic angiography (CTA) is considered the gold standard for post-EVAR surveillance, as it has the potential to visualise most threats to stent-graft durability, such as migration, ki...
