Why it pays off to know about contrast-enhanced ultrasound
Contrast-enhanced ultrasound is now an indispensable point-of-care or problem-solving tool, answering a clinical conundrum in minutes, if not seconds, says Prof. Paul Sidhu.

In a 47-year-old man with upper abdominal pain, ultrasound shows a fatty liver and an atypical lesion (arrow). The CEUS examination answered the question in 30 seconds -- this is a hemangioma, with classical pathognomonic peripheral globular enhancement (arrow). It’s a “slam-dunk” diagnosis: no further imaging, no further costs, and the patient knows immediately that this is benign. Figure courtesy of Prof. Paul Sidhu.

Lateral spreading tumors (LSTs). (a–c) Example of LST-non-granular (LST-NG). (a) Sagittal 2D-image with 40–400-HU abdominal window setting indicates a large 5.6-cm lesion with subtle diffuse thickening of the rectal wall (white arrows); the surface is partially covered by a thin layer of orally administered contrast agent. (b) The appearance of the villous mat on the 3D endoscopic view highlights the nodular aspect (white arrows) at the periphery of the lesion. (c) The optical colonoscopy view with the final diagnosis of a carpet villous adenoma with low-grade dysplasia. (d–f) Example of an LST-granular (LST-G) lesion. (d) Sagittal 2D image indicating nodular thickening of the rectum wall with a 10-mm nodule (white arrow). (e) The 3D endoscopic view visualized the irregular LST with a large nodule (white arrow), similar to (f) the endoscopic image obtained the same day after CTC. It confirmed the diagnosis and allowed mucosectomy with a final pathology report of a tubulous lesion with high-grade dysplasia.
