    Millions of Americans have them - hidden out of sight, underneath their skin. Implantable devices meant to fix what ails them. But these devices can present problems when it comes to getting an MRI. “The MRI machine itself is an incredibly strong magnet, very unique environment and whenever you’re placing anything that’s metal or anything that’s electronic into that environment, you have to make sure that it’s safe,” says Dr. Cory Duffek, who is a neuroradiologist for Lee Memorial Health System. For the most part, bone pins, artificial joints and titanium hips are made of non-magnetic material. Teeth crowns and dentures are also safe. Other implants may prevent a patient from getting this form of diagnostic test. “Like a nerve stimulator or a pacemaker. The other big ones are endovascular stents, coronary artery stents, stents in a patient’s aorta,” says Dr. Duffek. Over the past few decades, magnets have quadrupled in power and more scans are being performed than ever before. MRIs can detect dozens of serious ailments such as tumor and stroke-without radiation. Time has brought advances in technology- so that many newer devices are MRI-friendly. “This modality is similar to a pacemaker for pain,” says Dr. Gene Mahaney, who is a pain management physician on the medical staff of Lee Memorial Health System. The use of spinal cord stimulators to zap chronic pain is on the upswing. These devices were off-limits for magnetic imaging - until now. We were sometimes forced to remove devices, obtain an MRI, and re-implant them. Now with some of the new modalities, which are considered MRI safe, we can allow people to obtain an MRI down the road without any risk,” says Dr. Mahaney. MRI-friendly pacemakers are also available now and other devices are considered MRI conditional. “We have to make sure the scanner we’re going to scan that patient on meets all of those conditions,” says Dr. Duffek. As many as 70% of patients with an implanted device will need an MRI in the future, so it’s important to play it safe.

    • Ask the Expert: How Can We Test for Minimal Residual Disease (MRD) in Myeloma

      After treatment, what signs of myeloma remain in the body? While other patients with other blood cancers have tests for so-called Minimal Residual Disease (MRD), myeloma patients have had no such test. Now, thanks in part to the International Myeloma Foundation’s (IMF) Black Swan Initiative, myeloma researchers from around the world are attempting to answer these questions and develop the right tests for MRD. In this Patient Empowerment Network Ask the Expert video, Dr. Robert Orlowski addresses the current techniques employed for measuring treatment response as well as some of the newer techniques being studied. From PET and MRI scans, to whole genome sequencing of peripheral blood and flow immunophenotyping, myeloma researchers are looking for a consistent, powerful way to let patients know where their disease really stands.

      • Being Open to MRI

        It may offer the ultimate view of the human body- the MRI uses a magnetic field and radio wave pulses to make pictures of organs and structures; used to find problems such as tumors, bleeding, blood vessel diseases or infection. Getting the best images came at a cost. “Traditionally we had open MRIs and we have our closed MRIs. The closed MRIs are very claustrophobic but gave us the highest image quality and the best images. The open MRI was a much more patient-friendly environment but we couldn’t get very good images from it. And we’ve always had that problem,” says Dr. Cory Duffek, neuroradiologist with Lee Memorial Health System. Now its problem solved: the newest technology offers the high field magnet within an open setting. The images are high quality, with all the detail doctors are looking for. And the comfort is a pleaser for patients. Unlike an x-ray, which snaps a quick image, the MRI is time-consuming. Being in a closed tube for up to an hour can be unsettling for not only the claustrophobic, but children and people who are extremely overweight. “We have a table limit of 650 pounds, where in the past that was unheard of. So now we can accommodate and image people that have never been imaged before,” says Pete Kouba, MRI technologist with Lee Memorial Health System. Another patient population are those with back pain, this set up helps get them through testing. “We can add more pillows under their back; we can raise their head a little bit. If they can't lie on their back, they can lay on their side. And so we have much more options for patient positioning because we have more room to position the patient,” says Dr. Duffek. Being open to MRI is helping people get the treatment they deserve.

                David Shattuck (http://bit.ly/qWdhpD) presents a survey of the rapidly evolving field of biomedical imaging, and includes some stunning images from his own work on brain imaging. He also discusses the role played by data visualization, which is critical in diagnosis, validation, and interpretation. He identifies the key challenges as keeping apace with increasing data complexity, size, and interconnectedness. This talk was presented at VIZBI 2011, an international conference series on visualizing biological data (http://vizbi.org) funded by NIH & EMBO.
