Contrast‐Enhanced Ultrasound for Evaluation of Pleural Effusion

Journal of ultrasound in medicine, 2021
B‐mode ultrasound (B‐US) is the standard imaging modality to evaluate pleural effusion. The value of B‐US for assessing the malignancy of a pleural effusion (PE) is limited.

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.

Ultrasound Despeckling for Contrast Enhancement [PDF]

IEEE Transactions on Image Processing, 2010
Images produced by ultrasound systems are adversely hampered by a stochastic process known as speckle. A despeckling method based upon removing outlier is proposed. The method is developed to contrast enhance B-mode ultrasound images. The contrast enhancement is with respect to decreasing pixel variations in homogeneous regions while maintaining or ...

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.

Evaluation of renal perfusion in hyperthyroid cats before and after radioiodine treatment [PDF]

, 2017
Background: Hyperthyroidism and chronic kidney disease (CKD) are common in elderly cats. Consequently, both diseases often occur concurrently. Furthermore, renal function is affected by thyroid status. Because changes in renal perfusion play an important
