Differentiating Benign from Malignant Causes of Splenomegaly: Is Acoustic Radiation Force Impulse Elastography Helpful?

Purpose: To evaluate the ability of acoustic radiation force impulse (ARFI) elastography in differentiating benign from malignant etiologies of splenomegaly based on differences in splenic stiffness.

Materials And Methods: Between September 2020 and November 2022, we evaluated 40 patients with splenomegaly-defined by a splenic long axis greater than 13 cm and/or a short axis greater than 6 cm, without visible focal or infiltrative mass lesions-using abdominal ultrasound at our university hospital. Each patient also underwent a standardized ARFI elastographic assessment of the enlarged spleen, with data collected prospectively.

Endosonography in head and neck imaging and surgery.

This CME article explores the evolving role of endosonography in otorhinolaryngology and head and neck surgery. Endosonography offers significant potential to improve imaging inside the upper respiratory tract, particularly with advancements in probe technology and imaging resolution. The article will describe the sonoanatomy of the oral cavity, pharynx, and larynx and the selection of probes and scanning techniques used for the various anatomical sites.

Comments on EFSUMB recommendations, role of ultrasound in cutaneous neoplasms.

The European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) has been publishing guidelines, position papers and also technical reviews. In addition, comments have been published for illustration of such papers including the hepatobiliary system, pancreas, lung and other organs. In the current paper, we aim to summarize the typical sonographic findings of the most commonly seen cutaneous neoplasms.

Ultrasound measurements and normal findings in the thyroid gland.

The present work describes the process of the sonographic examination, normal findings and measurements in the B-mode ultrasound evaluation. Reference is made to anatomical variants in shape, the pyramidal lobe, tubercle of Zuckerkandl, ectopic thyroid tissue, and their significance. Particular attention is paid to the reference values, the very miscellaneous reference values in different geographic regions of the world and influencing factors.

[Imaging in chronic inflammatory bowel disease].

In patients with chronic inflammatory bowel disease (IBD), endoscopic techniques (including capsule techniques and balloon enteroscopy for the small intestine), ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) are primarily used as often complementary imaging techniques. Radiation exposure needs to be kept in mind when using CT and conventional X‑ray-techniques. Therefore, most importantly, ultrasound and MRI have changed the routine diagnostics of intestinal diseases.
