MRI Detection of Prostate Cancer Could Save Thousands of Lives at a Lower Cost

MRI Detection of Prostate Cancer Could Save Thousands of Lives at a Lower Cost

The best way to catch prostate cancer early could be entirely noninvasive, radiation-free, and low in cost. Multiparametric magnetic resonance imaging (MRI) with a targeted biopsy is more effective than the current standard — transrectal ultrasonography–guided biopsy — in detecting prostate cancer. That’s according to a study in the New England Journal of Medicine. The […]

Wearable MRI Scanner Allows New Observations of Brain Activity

Wearable MRI Scanner Allows New Observations of Brain Activity

Researchers at the University of Nottingham and University College London are developing a wearable magnetic resonance imaging (MRI) scanner. The helmet-like device uses an advanced technique called magnetoencephalography (MEG) to map brain activity. While MRI scans of the brain are nothing new, the mobile nature of the new technology will allow doctors to evaluate patients […]

How Diagnostic Imaging Protects Olympic Athletes

How Diagnostic Imaging Protects Olympic Athletes

The final injury statistics on the 2018 Winter Olympics aren’t in just yet, but previous research shows that diagnostic imaging plays a big role in keeping athletes competitive for the games. Quick assessment of injuries is crucial for effective treatment. This is particularly true in athletics, which subject the athlete’s body to sometimes-extreme stresses. MRI […]

What the FDA’s X-Ray Guidance Changes Mean for Parents

What the FDA’s X-Ray Guidance Changes Mean for Parents

The U.S. Food and Drug Administration (FDA) has released new guidelines for x-ray imaging in pediatric patients. The guidance intends to reduce unnecessary radiation exposure by educating imaging manufacturers, parents, pediatricians, and other health care professionals. X-ray imaging has many benefits, but there are risks associated with them. As with any medical procedure, there are […]

MRI of the Knee: What to Expect and How to Prepare

MRI of the Knee: What to Expect and How to Prepare

An MRI of the knee can reveal valuable information to a trained professional. Accidents, sports injuries, arthritis, or simple knee pain can warrant a doctor ordering a such a scan. MRIs are perfectly safe, and unlike X-rays and CT scans, they don’t use radiation. In fact, anxiety in anticipation of the scan can be the […]

The MRI Prescreening Process: What to Know

The MRI Prescreening Process: What to Know

Before every scan, patients must submit to an MRI prescreening process so radiologists can be sure everything goes smoothly during the procedure. It’s not that MRI scans are dangerous; in and of themselves, they aren’t. In fact, because they don’t expose patients to ionizing radiation, they’re much safer than X-rays. But MRI machines rely on […]
