Prostate Cancer Imaging With Radioactive Tracer and Ultrasound Detector Compared to MRI and ProstaScint

July 12, 2011 updated by: Radiological Associates of Sacramento Medical Group Inc.

Exploratory Evaluation of a Transrectal Scintigraphic Detector (Proxiscan) for Detection of Primary Prostate Cancer Utilizing a Radiotracer Targeting Prostate Specific Membrane Antigen (PMSA)

This is a small study to determine if probe, similar to an ultrasound probe, can detect prostate cancer more specifically than other imaging studies in patients with a positive prostate cancer biopsy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Detection of PSMA antibody (ProstaScint)uptake patterns measured by Proxiscan in comparison with anatomic biopsy reports, conventional SPECT and MRI scans within one month of Proxiscan
Time Frame: Within on month of scan and corresponding MRI
Detection of PSMA antibody (ProstaScint) uptake patterns measured by the new transrectal compact gamma camera (Proxiscan) will be compared to the anatomic biopsy reports along with Magnetic Resonance Imaging (MRI) and conventional ProstaScint (Single Photon Emission Computed Tomography) SPECT imaging results. All imaging and biopsy results performed within one month will be used for this investigation
Within on month of scan and corresponding MRI
