Walmer, R. W., Ritter, V. S., Sridharan, A., Kasoji, S. K., Altun, E., Lee, E., … Chang, E. H. (2023, October 12). Journal of Clinical Medicine.

By: R. Walmer n, V. Ritter *, A. Sridharan  n, S. Kasoji n, E. Altun *, E. Lee *, K. Olinger *, S. Wagner* ...

author keywords: chronic kidney disease; contrast-enhanced ultrasound; kidney lesions; performance metrics; screening tool
topics (OpenAlex): Renal cell carcinoma treatment; MRI in cancer diagnosis; Renal and related cancers
TL;DR: In CKD patients, CEUS is a potential low-risk option for screening kidney lesions, and may be particularly beneficial for CKD IV/V patients, where kidney preservation techniques are highly relevant. (via Semantic Scholar)
