Mesenteric Masses on 2D Mode and Contrast-Enhanced Ultrasound: A Retrospective Study in 69 Patients

Abstract

Hypoechogenicity and complex echogenicity in 2 D mode, irregular borders, and parenchymal wash-out were more often associated with malignancy. However, CEUS did not help to subclassify malignant MMs according to their histological entity.

Diagnostic Performance of Point Shear Wave Elastography (pSWE) Using Acoustic Radiation Force Impulse (ARFI) Technology in Mesenteric Masses: A Feasibility Study

“…The MAVs of sclerosing mesenteritis (15/69; 21.7%) (1.53 ± 0.96 m/s) were significantly lower than those of mMMs (32/69; 46.4%) (2.76 ± 1.01 m/s; p = 0.001). These results are important because sclerosing mesenteritis and mMMs may have similar features in different imaging modalities, such as CT or CEUS, and may not be differentiated from each other [ 11 , 41 ]. However, it should be noted that sclerosing mesenteritis may also be caused secondarily due to an underlying malignant disease [ 42 ].…”

“…In addition, magnetic resonance imaging (MRI), positron emission tomography–computed tomography (PET-CT), and B-mode ultrasound (US) are used for evaluating MMs [ 2 , 3 , 9 , 10 ]. As a new trend in US imaging, contrast-enhanced ultrasound (CEUS) is used to assess perfusion patterns of various pathologies, including MMs [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Another new trend in US imaging is US elastography, which is a non-invasive tool for assessing tissue stiffness, with guidelines available for hepatic and non-hepatic applications [ 21 , 22 , 23 , 24 , 25 , 26 ].…”
