A Generative Probabilistic Model and Discriminative Extensions for Brain Lesion Segmentation— With Application to Tumor and Stroke
We introduce a generative probabilistic model for segmentation of brain lesions in multi-dimensional images that generalizes the EM segmenter, a common approach for modelling brain images using Gaussian mixtures and a probabilistic tissue atlas that employs expectation-maximization (EM), to estimate the label map for a new image. Our model augments the probabilistic atlas of the healthy tissues with a latent atlas of the lesion. We derive an estimation algorithm with closed-form EM update equations. The method extracts a latent atlas prior distribution and the lesion posterior distributions jointly from the image data. It ...

Here's How Meditation Reduces Inflammation And Prevents Disease
Science has shown that mindfulness meditation can have a positive impact on a huge range of health conditions, including cancer, depression and post-traumatic stress disorder. The practice has even been found to slow HIV progression and protect the brain from aging.
Mindfulness seems to improve nearly every aspect of health -- but how? While mounting research has revealed many of the numerous physical and mental health benefits of mindfulness, little is known of the mechanisms underlying these positive changes.
Now, a new study from Carnegie Mellon University, published on Jan. 29 i...

Midbrain and bilateral paramedian thalamic stroke due to artery of Percheron occlusion
Conclusion Bilateral thalamic stroke due to artery of Percheron occlusion is a rare presentation of stroke, which can be overlooked in routine CT scan. If diagnosed, it requires further evaluation for stroke risk factors, especially cardiovascular disorders associated with increased embolic risk.

FDA Approves BIOTRONIK Iperia ICD Systems With Full-Body ProMRI Technology
BIOTRONIK has received FDAapproval for use of its latest family of implantable cardioverter defibrillator (ICD) systems with magnetic resonance imaging (MRI) scans. BIOTRONIK ProMRItechnology allows patients with approved device systems to have 1.5 Tesla MRI scans without an exclusion zone. ICD patients will have expanded access to MRI diagnostic scans, which can be critical for diagnosing conditions such as stroke, brain and cardiac tumors or orthopedic injuries.

Can You Think Yourself Into A Different Person?
For years she had tried to be the perfect wife and mother but now, divorced, with two sons, having gone through another break-up and in despair about her future, she felt as if she’d failed at it all, and she was tired of it. On 6 June 2007 Debbie Hampton, of Greensboro, North Carolina, took an overdose of more than 90 pills – a combination of ten different prescription drugs, some of which she’d stolen from a neighbor’s bedside cabinet. That afternoon, she’d written a note on her computer: “I’ve screwed up this life so bad that there is no place here for me and nothing I can contr...

Automated lesion detection on MRI scans using combined unsupervised and supervised methods
Conclusions:
In this paper, we introduced a novel automated procedure for lesion detection from T1-weighted MRIs by combining both an unsupervised and a supervised component. In the unsupervised component, we proposed a method to identify lesioned hemisphere to help normalize the patient MRI with lesions and initialize/refine a lesion probability map. In the supervised component, we extracted three different-order statistical features from both the tissue/lesion probability maps obtained from the unsupervised component and the original MRI intensity. Three support vector machine classifiers are then trained for the three f...

The Man Who Grew Eyes
The train line from mainland Kobe is a marvel of urban transportation. Opened in 1981, Japan’s first driverless, fully automated train pulls out of Sannomiya station, guided smoothly along elevated tracks that stand precariously over the bustling city streets below, across the bay to the Port Island. The island, and much of the city, was razed to the ground in the Great Hanshin Earthquake of 1995 – which killed more than 5,000 people and destroyed more than 100,000 of Kobe’s buildings – and built anew in subsequent years. As the train proceeds, the landscape fills with skyscrapers. The Rokkō mounta...

Hidden cancer rarely causes out-of-the-blue clots in the bloodstream
Blood clots can be lifesavers when they form outside the bloodstream to stop bleeding from an injury. But they can wreak havoc when they form inside the bloodstream. A blood clot in a coronary artery can cause a heart attack. One in the brain can cause a stroke.
Blood clots that form in a leg vein cause a problem known as venous thromboembolism, or VTE. If the clot stays in the leg, it can cause swelling or pain. If it breaks away and travels to the lungs, it can cause a potentially deadly pulmonary embolism.
In about half of people who develop a VTE, doctors can identify what caused it. Common causes include an injury; su...

Tissue-Specific Sparse Deconvolution for Brain CT Perfusion
Cerebral computed tomography perfusion (CTP) imaging has been advocated to detect and characterize the ischemic penumbra, and assess blood-brain barrier permeability with acute stroke or chronic cerebrovascular disease. In cerebral studies, perfusion hymodynamic parameters such as cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) can be computed from the time sequence of enhanced CT images to provide important guidance to clinicians. However, the associated excessive radiation exposure in the repeated scan during CTP examination is raising a great concern due to numerous recent reports from...

Calcification in high grade gliomas treated with bevacizumab
Abstract
Calcification is a rare phenomenon in high grade glioma (HGG). CT scans are sensitive to mineralization but used infrequently for tumor assessment in the MRI era. The presence of calcification can be overlooked on routine MRI. Calcification may reflect chronicity and natural changes in the tumor or its milieu over time and may be accelerated by certain treatments. Calcification may have clinical significance which could signal potential risk for stroke or hemorrhage related to particular therapies; or it may be a positive prognostic factor for treatment response. The true incidence and relevance of calcif...

Hospitalization after fainting can do more harm than good
One morning not long ago, my teenage daughter started to black out. After an ambulance ride to our local hospital’s emergency department, an electrocardiogram, and some bloodwork, she was sent home with a follow-up doctor appointment. We got the good news that Alexa is perfectly healthy, but should avoid getting too hungry or thirsty so she doesn’t faint again. And I’m feeling lucky that she didn’t need to be hospitalized, because a research letter in this week’s JAMA Internal Medicine points out that hospitalization for low-risk fainting can do more harm than good.
Doctors use something called th...
