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.

Condition Intervention Phase
Prostate Cancer Device: Proxiscan device Early Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Primary Purpose: Diagnostic
Official Title: Exploratory Evaluation of a Transrectal Scintigraphic Detector (Proxiscan) for Detection of Primary Prostate Cancer Utilizing a Radiotracer Targeting Prostate Specific Membrane Antigen (PMSA)

Primary Outcome Measures:
  • 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

Estimated Enrollment: 12
Study Start Date: June 2011
Estimated Study Completion Date: March 2012
Estimated Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: No intervention
All consenting patients will be imaged with the Proxiscan and data compared with MRI, ProstaScint and biopsy data
Device: Proxiscan device
All patients will be imaged with the device
