Contrast enhanced ultrasound of sentinel lymph nodes [PDF]

Journal of Ultrasonography, 2013
Sentinel lymph nodes are the first lymph nodes in the region that receive lymphatic drainage from a primary tumor. The detection or exclusion of sentinel lymph node micrometastases is critical in the staging of cancer, especially breast cancer and ...

Untargeted Contrast-Enhanced Ultrasound Versus Contrast-Enhanced Computed Tomography: A Differential Diagnostic Performance (DDP) Study for Kidney Lesions [PDF]

Clinics, 2020
OBJECTIVES: Histopathology is the ‘gold standard’ for diagnosing renal cell carcinoma but is limited by sample size. Contrast-enhanced ultrasound can differentiate malignant and benign lesions, but the Chinese guidelines on the management of renal cell ...

Contrast-enhanced ultrasound fundamentals: the pharmacodynamics and pharmacokinetics of contrast. Basics of contrast-enhanced ultrasound imaging

Radiología (English Edition)
Contrast-enhanced ultrasound (CEUS) is a medical imaging technique that offers multiple advantages over other modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). These advantages include portability, no ionising radiation and no renal toxicity, with the great advantage of real-time imaging.

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 ultrasound in oncology [PDF]

Cancer Imaging, 2011
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 ...
