Krebs, Nigel Colenbier, Hannes Almgren, Daniele MarinazzoAbstractPrevious studies have characterized the brain regions involved in encoding monetary reward and punishment outcomes. The question of how this information is integrated across brain regions has received less attention. Here, we investigated changes in effective connectivity related to the processing of positive and negative monetary outcomes using functional magnetic resonance imaging data from the Human Connectome Project. Specifically, subjects engag...

A 70-year-old female patient with a history of locally advanced breast cancer presented with a 2-month duration of persistent gait imbalance. Ten years earlier, she initially received a diagnosis of an invasive ductal carcinoma of the right breast, triple negative, treated with mastectomy and axillary lymph node dissection, followed by adjuvant chemotherapy and postmastectomy radiation therapy. She had been followed up without evidence of disease until the present time. Magnetic resonance imaging of the brain demonstrated a lobulated enhancing mass measuring 3.6  × 2.4 × 3.6 cm involvin...

Minimizing the overdiagnosis and overtreatment of localized prostate cancer is a huge challenge for both patients and health care systems. Evidence now supports the role of prebiopsy multiparametric magnetic resonance imaging (mp-MRI) as a triage tool.

ConclusionCRT should be considered for cT3N0 patients, but its timing (neoadjuvant vs. adjuvant) seems not to affect the disease-free survival in the present cohort of patients.

We describe the case of a 43-year-old patient who presented with a transient ischemic attack episode, desaturation and ventricular arrhythmias. Transesophageal echocardiography diagnosed a PFO, whilst magnetic resonance imaging revealed two small myocardial infarcts, despite normal coronaries on subsequent angiography. Echocardiography and cardiac CT revealed a LACV with bidirectional flow. The patient underwent percutaneous LACV and PFO closure, with immediate saturation increase following occlusion of the LACV. To the best of our knowledge, this is the first time a LACV is identified as the cause of recurrent thromboembolic events.

Todd ConstableAbstractThe goal of human brain mapping has long been to delineate the functional subunits in the brain and elucidate the functional role of each of these brain regions. Recent work has focused on whole-brain parcellation of functional Magnetic Resonance Imaging (fMRI) data to identify these subunits and create a functional atlas. Functional connectivity approaches to understand the brain at the network level require such an atlas to assess connecti...

AbstractPurposeTo compare the effects of gadoxetic acid and gadoteric acid on the image quality of single-breath-hold, triple (first, second, and third) arterial hepatic magnetic resonance imaging (MRI).MethodsTwo hundred and eleven patients were divided into two groups according to the contrast materials used (gadoxetic acid, 108 patients and gadoteric acid, 103 patients). All 3.0-T MR examinations included triple arterial phase acquisition using the 4D enhanced T1-weighted high-resolution isotropic volume examination (eTHRIVE) keyhole technique. The image qualities of the pre-contrast and triple arterial phases were asse...

Authors: Chen Y, Shaw JL, Xie Y, Li D, Christodoulou AG Abstract High spatiotemporal resolution dynamic magnetic resonance imaging (MRI) is a powerful clinical tool for imaging moving structures as well as to reveal and quantify other physical and physiological dynamics. The low speed of MRI necessitates acceleration methods such as deep learning reconstruction from under-sampled data. However, the massive size of many dynamic MRI problems prevents deep learning networks from directly exploiting global temporal relationships. In this work, we show that by applying deep neural networks inside a priori calculated tem...
