[CEUS-diagnosis of solid renal tumors]

Area of Science:

• Urology
• Radiology
• Oncology

Background:

• Renal lesions are increasingly detected via ultrasound, but differentiating tumor types remains challenging.
• Standard radiological methods like CT and MRI are used for evaluating renal tumors >1 cm for malignancy.

Purpose of the Study:

• To evaluate the role of Contrast-enhanced ultrasound (CEUS) in the diagnosis and differentiation of renal lesions.
• To assess CEUS's contribution to renal tumor detection and characterization compared to conventional ultrasound.

Main Methods:

• Utilized CEUS to assess microperfusion in renal tumors.
• Compared CEUS performance with B-mode and Doppler ultrasound for lesion detection and characterization.
• Integrated CEUS findings with other imaging modalities for comprehensive evaluation.

Main Results:

• CEUS provides clear information on renal tumor microperfusion.
• CEUS enhances the detection of renal tumors and aids in differentiating cysts and papillary renal cell carcinomas.
• CEUS can confidently rule out cortical pseudolesions and assists in diagnosing focal pyelonephritis, abscesses, and lymphoma.

Conclusions:

• CEUS, particularly when combined with other ultrasound techniques, is valuable for diagnosing various renal lesions and supporting biopsy planning.
• Accurate renal tumor diagnosis requires integrating multiple imaging techniques and multidisciplinary tumor board review for personalized treatment.
