Brief Summary

Prostate cancer is the most common cancer in men. It is most often detected by an abnormal digital rectal exam or an elevated Prostate-Specific Antigen -determine by a blood test. When it is suspected that someone may have prostate cancer, a biopsy is ordered. This biopsy is performed by the Radiologist with ultrasound guidance through the rectum. In some patients, a Magnetic Resonance Imaging (MRI) scan of the prostate may be ordered to further evaluate the prostate. In some situations, the MRI and Ultrasound images will be fused (digitally merged) together during the ultrasound procedure to help localize the questionable lesions. Recent research has used an additional component known as a contrast agent - an intravenously injected inert substance - which is identifiable by ultrasound. This inert substance is more obvious in areas of increased blood flow, which is a common finding in cancerous lesions. In this research project, we would like to determine whether the use of contrast-enhanced ultrasound is beneficial in improving accuracy of the biopsies taken and the relative correlation to the MRI/ Ultrasound-fused images.

Outcome Measures

Primary Outcomes (1)

  • Measure the quality and pathology results of prostate samples taken during Contrast-Enhanced Ultrasound (CEUS) with MRI/ Ultrasound fusion.

    It is hypothesized that the introduction of the Definity contrast agent during the ultrasound biopsy will increase the accuracy of the targeting biopsy sample, as well as reduce the number of targeted biopsies of non-cancerous lesions. We will compare the MRI characteristics of the prostate lesions in question in real-time ( as the MRI and Ultrasound will be fused together ), and determine whether questionable lesions seen under MRI have increased flow dynamics

    1 Day

Secondary Outcomes (1)

  • Measure whether the use of Contrast-Enhanced Ultrasound (CEUS) on prostate cancer detection rates when incorporated with MRI / Ultrasound Fusion differs from non-CEUS prostate biopsies performed under MRI/ Ultrasound Fusion guidance

    1 Day

Other Outcomes (1)

  • Generate a Time Intensity Curve for prostate cancer lesions and measure the relation of that value to the MRI Apparent Diffusion Coefficient (ADC) value of the lesion.

Study Arms (1)

Definity Perflutren Suspension

ACTIVE COMPARATOR

Injection of Definity Perflutren Injectable Suspension- which travels in the bloodstream throughout the body. These microbubbles are identifiable on ultrasound imaging, and studies of the liver and kidney have identified it as a useful adjunct to identifying vascular lesions. Areas of regular blood flow will not have as large a concentration of the microbubble agent as will areas that have increased blood flow and neovascularisation. It has been well documented that cancerous solid lesions undergo neovascularisation and have increased blood flow to the area.

Device: Definity Perflutren Injectable Suspension

Interventions

a single dose of 10 μL/kg of the activated product by intravenous bolus injection over 30-60 seconds, followed by a 10 mL saline flush. If necessary, a second 10 μL/kg dose may be administered 5 minutes after the first injection to prolong contrast enhancement
