Diagnostic accuracy and interobserver agreement of contrast-enhanced ultrasound in the evaluation of residual lesions after treatment for malignant lymphoma and testicular cancer

Purpose: To calculate the diagnostic accuracy and interobserver agreement of contrast-enhanced ultrasound (CEUS) in the evaluation of residual lesions after treatment for malignant lymphoma and metastatic testicular cancer. Materials and methods: Between May 2004 and October 2010 an experienced sonographer performed CEUS in 52 patients with residual lesions after treatment for malignant lymphomas and metastatic testicular cancer. Final judgement on presence or absence of active disease was based on histological findings and/or clinical follow-up. To quantify the diagnostic accuracy of the CEUS we calculated sens…
