Trial Information

Contrast-enhanced Ultrasound for Follow-up After Radiofrequency Ablation of Renal Lesions: a Prospective, Blinded Study


Inclusion Criteria:



- at least 18 years of age and capable of giving informed consent

- patient undergoing CT of MRI for monitoring of renal lesions after radiofrequency
ablation

Exclusion Criteria:

- pregnant patients

- patients with allergies to iodinated contrast agents

- patients with pulmonary hypertension, right-to-left cardiac shunts, or unstable
cardiopulmonary disease (these are absolute or relative contraindications to the use
of the ultrasound contrast agent, perflutren lipid microsphere)

Type of Study:

Interventional

Study Design:

Allocation: Non-Randomized, Intervention Model: Single Group Assignment, Masking: Single Blind (Outcomes Assessor), Primary Purpose: Screening

Outcome Measure:

Sensitivity value of CEUS for tumour recurrence and by comparing to the standard CT/MRI.

Outcome Description:

The accuracy of contrast-enhanced ultrasound in monitoring renal lesions post-radiofrequency ablation will be assessed through sensitivity, specificity, and positive predictive value of CEUS for tumour recurrence and by comparing to the standard CT/ MRI.

Outcome Time Frame:

3 months post radiofrequency ablation procedure.

Safety Issue:

No
