Prediction of radiation necrosis in a rodent model using magnetic resonance imaging apparent transverse relaxation (R 2 * ).

Conclusions: The ability to predict areas of RN and increases of R2* within the hippocampus provides a method for long-term monitoring and prediction of RN. PMID: 29219117 [PubMed - as supplied by publisher]

ConclusionsPre-biopsy mpMRI for clinically suspected prostate cancer is emerging as a standard of practice in Ireland. International guidelines are also changing to reflect latest clinical trial evidence. Private health insurance providers should amend their policies to reflect current clinical practices already adopted in the public sector.

Authors: Raisbeck LD, Diekfuss JA, Grooms DR, Schmitz R Abstract CONTEXT: Although the beneficial effects of using an external focus of attention are well documented in attainment and performance of movement execution, neural mechanisms underlying external focus' benefits are mostly unknown. OBJECTIVE: To assess brain function during a lower-extremity gross motor movement while manipulating an internal and external focus of attention. DESIGN: Cross-over study. SETTING: Neuroimaging center Participants: A total of 10 healthy subjects (5 males and 5 females) Intervention: Participants completed external a...

ConclusionsWithin the main limitation of this pilot study, that is, the small sample, it is possible to state that cephalometric measurements on 3T-MRI seem to possess adequate reliability and repeatability and that they show satisfying agreement with values measured on CBCTs. An MRI examination does not expose patients to ionizing radiation and could provide an alternative to CBCT for three-dimensional cephalometrics in the future.

Abstract The diagnosis of prostate cancer has changed. Improved magnetic resonance imaging (MRI) technology with diffusion-weighted imaging has led to the use of multiparametric MRI (mpMRI) before biopsy in patients suspected of having prostate cancer. This has the advantage that patients with a negative mpMRI may not need biopsy, therefore avoiding the risk of complications. Those in whom mpMRI is positive can have targeted biopsies with a higher probability of diagnosing clinically significant cancer. Prostate Cancer UK (PCUK) and the British Society of Urogenital Radiology submitted a Freedom of Information (FO...

We present the theoretical considerations of f-FTLD and the aims/objectives of this protocol. We also describe the design and methodology for evaluating and rating subjects, in which detailed clinical and neuropsychological assessments are performed, biofluid samples are collected, and magnetic resonance imaging scans are performed using a standard protocol.DiscussionThese data and samples, which are available to interested investigators worldwide, will facilitate planning for upcoming disease-modifying therapeutic trials in f-FTLD.

Gotlib, Brian KnutsonAbstractAlthough behavioral sensitivity to reward predicts the onset and course of mania in bipolar disorder, the evidence for neural abnormalities in reward processing in bipolar disorder is mixed. To probe neural responsiveness to anticipated and received rewards in the context of bipolar disorder, we scanned individuals with remitted bipolar I disorder (n=24) and well-matched controls (n=24; matched for age and gender) using Functional Magnetic Resonance...

A general surgeon in North Carolina wants to buy a new magnetic resonance imaging (MRI) machine to make procedures more affordable, but the state won ’t allow him. Now he’s suing. According to the  lawsuit, Forsyth Imaging owner Gajendra Singh, MD, was concerned about the fact that many patients were struggling to afford imaging services. He wanted to offer imaging services at affordable prices, and help his patients easily determine their out-of-pocket expenses. He had built a transparent pricing model, and posted procedure rates on Forsyth ’s website. He claims that his prices are lower than o...

Authors: Suo F, Zhong B, Lu F, Dong Z Abstract Glioma is the most aggressive brain tumor and is associated with a high mortality rate. The aim of the present study was to explore the association between matrix metalloproteinase 2 (MMP-2) and ephrin type-A receptor 2 (EphA2) expression in glioma cells, and to investigate the contribution of magnetic resonance imaging (MRI) in glioma classification. A total of 43 patients with pathologically confirmed glioma were divided into two groups as follows: Low-grade (grades I and II; n=21) and high-grade (grades IV and IV; n=22). Subsequently, immunohistochemistry staining w...
