Growing indications for CEUS: The kidney, testis, lymph nodes, thyroid, prostate, and small bowel

Area of Science:

• Radiology
• Medical Imaging

Background:

• Contrast enhanced ultrasonography (CEUS) is expanding beyond liver applications.
• CEUS is being utilized for various pathologies in organs like the kidney, testis, and small bowel.

Purpose of the Study:

• To explore the expanding non-hepatic applications of CEUS.
• To review the utility of CEUS in diagnosing pathologies of the kidney, testis, small bowel, thyroid, and prostate.

Main Methods:

• Review of existing literature and clinical investigations on CEUS for non-hepatic applications.
• Analysis of CEUS performance in differentiating benign from malignant lesions, detecting sentinel nodes, and evaluating treatment outcomes.

Main Results:

• CEUS demonstrates growing clinical utility in kidney, testis, and small bowel pathologies.
• Investigated applications include differentiating cancerous lymph nodes, sentinel node detection, thyroid nodule assessment, and prostate cancer evaluation.
• While initial prostate cancer detection results were promising, they have not been fully realized; however, CEUS shows potential in assessing devascularization after ablative treatments.

Conclusions:

• CEUS is a versatile imaging modality with increasing non-hepatic applications.
• Further research and validation are ongoing for specific organ systems and pathologies, particularly in prostate cancer assessment.
