It is the hypothesis that cancerous lesions in the prostate will have an increased amount of blood flow, and that the lesions identified under ultrasound with the benefits of contrast-enhanced imaging can be correlated to the MRI Findings in real-time. A study of 50 patients who would be undergoing MRI/Ultrasound fusion would be selected to have contrast added to their procedure. The lesions identified on MRI would then be evaluated with contrast-enhanced ultrasound. The findings from the contrast study could then be correlated with the MRI findings. The rest of the prostate gland would also be assessed using the contrast agent for lesions not identified on the MRI imaging study. The pathology results could be correlated with both the contrast study and the MRI study both independently, and in conjunction with the two imaging modalities. If a correlation between highly suspicious lesions on the MRI and significant flow patterns under contrast can be established, then the sensitivity and specificity of contrast-enhanced ultrasound can be increased.
