ABSTRACT
PURPOSE:
Contrast-enhanced-ultrasound (CEUS) has been frequently used in assessment of cystic renal lesions.OBJECTIVE:
The aim of this study was to investigate the Bosniak classification in CEUS compared to CT and MRI in a multi-center setting.METHODS:
Bosniak classification in CEUS examinations of cystic renal lesions were compared to imaging findings in computed-tomography (ceCT) and magnetic-resonance-imaging (ceMRI). Imaging results were correlated to histopathological reports. All examinations were performed by experts (EFSUMB level 3) using up-to-date CEUS examination-protocols.RESULTS:
Overall, 173 cystic renal lesions were compared to subgroups CT (nâ=â87) and MRI (nâ=â86). Using Bosniak-classification 64/87 renal cysts (73.6%) were rated equal compared to CT with upgrade of four lesions (4.6%) and downgrade of 19 lesions (21.8%) by CT (Intra-class-correlation [ICC] coefficient of 0.824 [pâ<â0.001]). CEUS compared to MRI, presenting different scoring especially in classes Bosniak IIF (nâ=â16/31) and Bosniak III (nâ=â16/28) with an ICC coefficient of 0.651 (pâ<â0.001).CONCLUSION:
CEUS can visualize even finest septal and small nodular wall enhancement, which may result in an upgrade of cystic lesions into a higher Bosniak class compared to CT or MRI. Thus, a modification of the Bosniak classification on CEUS may reduce unnecessary biopsies and surgery.Palabras clave
