Summary
Contrast-enhanced sonography significantly improves splenic trauma assessment compared to traditional methods. This technique enhances the detection and characterization of splenic injuries, making sonography a more effective initial imaging procedure.
Area of Science:
- Radiology and Imaging
- Emergency Medicine
- Trauma Surgery
Background:
- Accurate and timely assessment of splenic trauma is critical for patient management and outcomes.
- Traditional sonography has limitations in detecting subtle splenic injuries and characterizing their severity.
Purpose of the Study:
- To evaluate the efficacy of contrast-enhanced sonography (CES) using a second-generation contrast agent in diagnosing splenic trauma.
- To compare the diagnostic performance of CES with unenhanced sonography and contrast-enhanced computed tomography (CECT).
Main Methods:
- 120 patients with suspected splenic trauma underwent sonography.
- 25 selected patients underwent both CES and CECT.
- Comparison of imaging findings for hemoperitoneum, splenic lesions, infarctions, hypoperfusion, and contrast extravasation.
Main Results:
- CES demonstrated superior performance over unenhanced sonography in detecting splenic injuries and assessing their extent.
- CES identified parenchymal lesions in 17 of 18 injured spleens, compared to 12 with unenhanced sonography.
- CES and CECT detected findings like splenic hypoperfusion and contrast pooling more effectively than unenhanced sonography.
Conclusions:
- Contrast-enhanced sonography is a valuable and promising tool for evaluating splenic trauma.
- Implementing CES as an initial imaging modality can enhance the diagnostic capabilities of sonography in trauma centers.
