Summary

This is a feasibility, exploratory, and proof-of-concept study to evaluate rectal probe scintigraphy device (ProxiScanTM) to detect PSMA specific radiopharmaceutical agent (ProstaScint®) in patients with suspected primary prostate cancer. ProxiScanTM is a small cadmium zinc telluride (CST)-based compact gamma camera the size of a trans-rectal ultrasound (TRUS) developed by Hybridyne Imaging Technologies, Inc.To explore the adjunctive benefit/feasibility of PSMA distribution in the normal prostate versus prostate cancer gland utilizing TRUS and CT/SPECT hybrid imaging, biopsy negative patients will be considered as normal controls. Prostate cancer sextant biopsy histology results will be correlated with ProxiScanTM, TRUS, and pelvis planar and SPECT/CT. Our hypothesis is that it will be safe and feasible to utilize a rectal probe scintigraphy (ProxiScanTM) to detect PSMA specific ProstaScint® uptake in primary prostate cancer.

  • Suspected Primary Prostate Cancer

Interventions

DEVICE

ProxiScan (scintigraphic rectal probe)

ProxiScanTM is a compact, high-resolution gamma camera which has been developed for the detection of cancer and other abnormalities in the body by imaging the distribution of radionuclides in the human body using planar imaging techniques. This camera is capable of high-performance imaging of radiopharmaceuticals distributed within anatomical regions of interest located close to the camera head. The ProxiScan compact scintigraphic detector was approved by the FDA to market the device for the following indication: "The ProxiScanTM is indicated for use in imaging the distribution of radionuclides in the human body using planar imaging techniques. ProxiScanTM may also be used intraoperatively, on pathological specimens and for endocavity applications if a protective sheath is used."
