Imaging of the Prostate Gland Using High Field Strength 3T MRI

Condition: Prostate Cancer


  • Procedure: 3-Tesla magnetic resonance imaging (3T MRI)
  • Procedure: diffusion-weighted magnetic resonance imaging
  • Procedure: dynamic contrast-enhanced magnetic resonance imaging
  • Procedure: magnetic resonance spectroscopic imaging

Purpose: In standard clinical care, the prostate is imaged by magnetic resonance imaging (MRI) which is a procedure to take pictures of body structures by using a strong magnetic field and radio waves. The strength of the magnet used is expressed in the unit Tesla (T); a higher Tesla number means the magnet has stronger pull. Standard magnetic resonance imaging of the prostate uses a magnet 1.5 Tesla strong as well as a specialized endorectal coil (antenna) inserted into the body due to the limitations using an external body coil at this magnet strength. MRI using a 3 Tesla magnet has a theoretical advantage over imaging at 1.5 Tesla of creating a signal twice as strong that can be received by the antennas, resulting in better pictures. The goal of this study is to make the MRI procedure more comfortable for patients by using an external coil instead of an endorectal coil. With this study, researchers also want to help patients’ health care teams, the surgeons in particular. Researchers will assess the impact of prostate MRI, without an endorectal coil, done at 3 Tesla and with an external body coil on helping doctors decide which approaches to disease therapy might be best for patients as well as correlate patients’ study images with all other clinical imaging

  • Patients that exhibit noticeable anxiety and/or claustrophobia
  • Patients who cannot adhere to the experimental protocols for any reason, or have an inability to communicate with the researcher
  • Patients who have cardiac or known circulatory impairment, and/or the inability to perspire (poor thermoregulatory function)
  • Patients with an estimated glomerular filtration rate of < 30 mL/min/1.73m^2 within six weeks of the MRI
