Four Imaging Approaches Can Differentiate Malignant and Benign Breast Tumors

Imaging breast tumors using four approaches together, can better distinguish malignant breast tumors from those that are benign, compared with imaging using fewer approaches, and this may help avoid repeat breast biopsies.   More...

Image: Silicon mesoporous particles (SiMPS), measure about 1,000 nm across contain thousands of much smaller particles of iron oxide. The SiMPs can be manipulated by magnets and gather at the site of tumors, where they can be heated to kill malignant tumors or trigger the release of drugs. The particles were created by an international team led by scientists at Rice University and Methodist Hospital Research Institute (Houston, TX, USA) (Photo courtesy of Rice University).

“Nanoconstructs” Designed to Enhance MRI Technology

Submicrometer particles that contain even smaller particles of iron oxide could make magnetic resonance imaging a much more effective way to detect and fight disease.   More...

Image: Left, the brains of adults who had ADHD as children but no longer have it show synchronous activity between the posterior cingulate cortex (the larger red region) and the medial prefrontal cortex (smaller red region). Right, the brains of adults who continue to experience ADHD do not show this synchronous activity (Photo courtesy of Jose-Luis Olivares/MIT - based on images courtesy of the researchers).

fMRI Brain Scans Reveal Differences in Adults Who Have Recovered from Childhood ADHD and Those Who Did Not

In a study to compare patterns of brain activity in adults who recovered from childhood with attention deficit hyperactivity disorder and those who did not, neuroscientists have discovered key differences in a brain communication network that is active when the brain is at wakeful rest and not focused on a particular task.   More...

PET/MR Found Best Imaging Modality for Detecting Coronary Arterial Disease

The hybrid molecular imaging technique called PET/MR imaging, which provides vital data about cardiac and arterial function, has been found to be an effective molecular imaging tool for detecting coronary artery disease, according to a recent study.  More...
