Introduction/Purpose: Among its many applications, contrast-
enhanced ultrasonography (CEUS) is used with very good
results in oncology imaging to evaluate the effect of several
therapeutic interventional radiology techniques. The aim of
this study is to evaluate the efficacy of CEUS in postoperative
renal tumor imaging.
Material and Method: The study group consisted of 17 consecutive
patients (11 males and 6 females, aged between 71 and
87) who underwent palliative embolization or chemoembolization
of renal tumors between January 2008 and December
2017. All patients underwent preoperative imaging with CEUS
and CT scan and they were followed postoperatively with CEUS
and CT scan for up to 24 months after initial intervention. The
ultrasound and CT operators were blind to each other’s findings.
Results: CEUS proved to be an effective means of monitoring
both arterial embolism and RFA of renal tumors with comparable
findings with CT and could be an alternative technique
to CT and MRI.
