Prevalence of Cerebral Small-Vessel Disease in Long-Term Breast Cancer Survivors Exposed to Both Adjuvant Radiotherapy and Chemotherapy Breast Cancer
Conclusion More CMBs were found in the aRCeBCS group than in the population-based controls. These vascular lesions potentially mark cerebrovascular frailty that could partially explain the well-documented association between chemotherapy and cognitive dysfunction. No support was found for a radiotherapy-related origin of CMBs.

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...

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...

Susceptibility-Weighted Angiography Visualizes Hypoxia in Cerebral Veins
Conclusions: Hypoxia leads to visible and measurable changes in cerebral veins as depicted through SWAN. Possible clinical implications of this finding include stroke and tumor imaging and need further investigation.

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...

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...

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...

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...

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.

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...

Brain findings on FDG PET-MRI body sequences that include the head
Conclusions FDG PET-MRI imaging is a rapidly evolving modality that is most commonly employed for cancer evaluation. The standardized base of skull to mid thigh imaging may miss many important pathologies that are discovered even with MRI body sequences. We propose that PET-MRI body sequences that include the head may show added value in the management of patients.

Density heterogeneity and fluid-blood levels in patients aged over 55 with lobar hematoma.
CONCLUSION: Density heterogeneity and, to a lesser degree, FBLs are frequently seen in patients aged>55 with LH. FBLs may also be associated with CAA-related hemorrhage. PMID: 27338204 [PubMed - as supplied by publisher]
