Contrast-enhanced sonography in blunt scrotal trauma().

Area of Science:

• Radiology
• Medical Imaging
• Urology

Background:

• Blunt scrotal trauma diagnosis can be challenging with conventional ultrasound.
• Accurate and timely diagnosis is crucial for managing scrotal injuries and preventing complications.

Purpose of the Study:

• To evaluate the diagnostic efficacy of contrast-enhanced ultrasonography (CEUS) versus basic ultrasound (US) in blunt scrotal trauma.
• To assess if CEUS enhances diagnostic confidence and provides critical information for patient management.

Main Methods:

• A prospective study involving 40 consecutive patients with blunt scrotal trauma.
• High-resolution US, color-power Doppler, and low mechanical index CEUS with intravenous SonoVue® were employed.
• Findings from basic US and CEUS were compared for concordance and diagnostic relevance.

Main Results:

• CEUS demonstrated higher sensitivity in detecting scrotal trauma, particularly small lesions.
• Additional information from CEUS was rated as highly or moderately relevant in 27.5% of cases.
• CEUS uniquely diagnosed testicular ruptures in 2 out of 3 patients, guiding surgical decisions.

Conclusions:

• CEUS significantly improves diagnostic confidence in blunt scrotal trauma evaluation.
• The technique is valuable for differential diagnosis and identifying injuries like ruptures that necessitate urgent surgical intervention.
• Larger studies are recommended to confirm these findings.
