Contrast-enhanced endoscopic ultrasound
Endoscopic Ultrasound, 2012 The European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) introduced guidelines on the use of contrast-enhanced ultrasound (CEUS) in 2004. This EFSUMB-document focused mainly on liver applications. However, new applications extending beyond the liver were developed thereafter.

Contrast‐enhanced endoscopic ultrasound [PDF]
Digestive Endoscopy, 2013 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.

Early Contrast Enhancement: a novel Magnetic Resonance Imaging biomarker of pleural malignancy [PDF]
, 2018 Introduction: Pleural Malignancy (PM) is often occult on subjective radiological assessment. We sought to define a novel, semi-objective Magnetic Resonance Imaging (MRI) biomarker of PM, targeted to increased tumour microvessel density (MVD) and ...

Contrast-enhanced coronary MRA [PDF]
Journal of Magnetic Resonance Imaging, 1999 Coronary angiography with magnetic resonance imaging (MRI) has long been a goal for bringing cardiac MRI into clinical use for diagnosis of coronary artery disease. In this paper, the fundamental problems of respiratory and cardiac motion, signal-to-noise ratio, and contrast-to-noise ratio are discussed in reference to implications for coronary imaging

Intra-arterial versus intra venous contrast-enhanced computed tomography of the equine head [PDF]
, 2016 Background: The anatomical complexity of the horse’s head limits the abilities of radiography. Computed tomography (CT) in combination with contrast enhanced CT is used more often for diagnosing various head pathology in horses.
