MRI-Robot Helps Target Cancer

MRI (magnetic resonance imaging) has recently been demonstrated to help in the diagnosis of prostate cancer, especially in men with a prior negative biopsy or those meeting criteria for active surveillance (See our prior blog on MRI and Active Surveillance). Traditionally prostate biopsies are performed with ultrasound imaging – which is great at targeting the prostate, but not necessarily for finding prostate cancer. Fusing MRI and ultrasound imaging is a recent advance that has helped urologists make use of the precision of MRI for finding tumors and the targeting of ultrasound to sample them.

Fusing MRI and ultrasound images can be complex and does not always work perfectly. If the tumor could be targeted with MRI, the extra step of fusion could be avoided. However, MRI machines make use of extremely strong magnets and metal instruments cannot be near the machine when it is turned on. This makes it impossible to use metal needles or machines with any metal components (including electrical wiring).

Researchers at Johns Hopkins, led by Dan Stoianovici, PhD, Director of the Urology Robotics Program, have developed a completely MRI-compatible robot to target the prostate and cancers within it. The robot makes use of pneumatic system composed of rubber and plastic tubing, screws and gears to manipulate a MRI-compatible needle to target the prostate. "The robotic device mounts on the MRI table alongside the patient. The physician selects a suspicious region that the MRI has shown, and the robot automatically guides the needle to target and presets the depth of insertion."

"To the best of our knowledge, this is the only robot approved by the FDA to operate in the MR environment in general, not only for the prostate."

The MR-bot (MRI-robot) has been approved by the Food and Drug Administration (FDA) and Insitutional Review Board (IRB) of Johns Hopkins for a clinical trial in humans. Urologists Mohamad Allaf, MD and Ashley Ross, MD, PhD, perform the biopsies. The first few cases indicate that robotic biopsy is safe and feasible.


With more precise imaging and techniques, urologists may continue to improve the precision of prostate biopsies. This work was awarded best paper of the Engineering and Urology Society of the American Urological Association.

  1. I had no idea that urologist worked along side radiologist when it came to patient care. This was a very interesting article about how MRI's are able to help the two determine what is going on with a patient. There really seem to be a lot of different options for those in the medical field when it comes to finding a way to help their patients. Thank you for taking the time to share this information. http://drmatthewbui.com/dr-matthew-bui-ph-d/

  2. While we still have a great deal of work to do to get tobacco under control in the United States, the situation is even more pressing across the globe, where tobacco companies use heavy-handed tactics to squelch anti-tobacco efforts. cancer treatment options available

  8. Get rid of Cold Sores, unexpected Outbreak and Herpes Virus? then you don't have to keep waiting for treatment when the is a herbal medicine that cure this virus. I was searching online for Herbal Cure for Herpes Virus when I saw a testimony online about Dr. Akintunde and how he cured a lady of HSV1 with his.
    natural herbal medicine and tested Negative and in less than a month she was cured of this virus. So it took me time to believe that this was true, because my family Doctor tried all his best to get rid of this virus in my body system but yet no cure and I suffered from outbreak and Cold Sores always. I had to contact Dr. Akintunde after I have access his website and i had faith in God that I was going to be fine and free of this virus one day. Finally I contacted Dr. Akintunde on his WhatsApp number that I saw on the testimony post online, and after our conversation the Doctor only promise me that I was going to be cured and free of this virus after taking his natural herbal medicine because I was tired of my situation with this virus it was so distracting to my life and whole family. Later Dr. Akintunde send some Herbal medicine to me through UPS courier service, with instructions on how to used this medicine, to my biggest surprise first week of taking my herbal medication I saw great improvement and I still think that it's a dream but this is real, I now test Negative of this virus today and my blood pressure well regulated now, my family doctor after my test was extremely surprise to see my test result change to HSV1 Negative and no more symptoms, cold sores, sores throat and outbreak again. I wish to tell everyone about this, mostly if you have this virus then do yourself good to contact Dr. Akintunde and see what the Lord can do through this Herbal Doctor's medicine in less than a month. 100% free from herpes Virus. I and my family say "thank you" Sir, for helping my life. You are a blessing to this generation and God will reward you richly
