A Prospective Histopathologic Study of Dynamic Contrast Enhanced MRI for Prostate Cancer Delineation and Characterization With the APT-MRI System
Abstract
This study will examine the usefulness of an imaging procedure called dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for localizing and characterizing prostate cancer. For this test, a medicine is injected into a vein and the MRI measures how the medicine flows through the prostate gland. The measurements provide information about the blood vessels in the prostate gland, which provides other information about the cancer. Several needle biopsies are performed during the procedure, and the results of the biopsies are compared with the information from the DCE-MRI.
Men 18 years of age and older with suspected or confirmed prostate cancer may be eligible for this study. Candidates are screened with a medical history and physical examination, blood test, and review of tumor pathology.
Participants undergo DCE-MRI and needle biopsies of the prostate. The day before and the morning of the procedure, patients are given an antibiotic called Levofloxacin. They also have a small enema the morning of the test. A local anesthetic is then given in the area around the prostate to numb the tissue and decrease any discomfort from the procedure. A tube is placed in the rectum to obtain better pictures of the prostate gland during the imaging. During the scan, the patient may be asked to breathe air that contains higher concentrations of oxygen and carbon dioxide than are in room air. The MRI scans guide the physician in selecting areas of the prostate to biopsy. For each…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 20 participants or records.
