Medical students' skills in research: unveiling their potentials. Shoulder MRI as a model
CONCLUSIONS: The agreement between the students and the orthopedic surgeon was highly significant. The intraobserver and interobserver reliabilities were also highly significant. Findings of the current study show that MRI series measurements can be performed with high accuracy after proper instruction is given to readers, regardless of their level of training.PMID:35179755 | DOI:10.26355/eurrev_202202_27998

Intensity-based image registration using scatter search
Conclusions With a proper, problem-specific design, scatter search is able to provide a robust, global optimization. The accuracy and reliability of the registration process are superior to those of classic gradient-based techniques.

Specificity and sensitivity of magnetic resonance imaging findings in the diagnosis of progressive supranuclear palsy
Summary Progressive supranuclear palsy (PSP) is a neurodegenerative condition that can only be diagnosed conclusively on pathological examination. Currently, the diagnosis is based upon the National Institute of Neurological Disorders and Stroke and the Society for PSP criteria. These criteria consist of purely clinical findings. Elements of brain MRI that are being investigated for this role include identifying structural features on conventional MRI, volume changes, signal abnormalities and diffusion changes. The aim of this study is to conduct a systematic search to identify which MRI findings have evidence to support t...

The dependencies of fronto‐parietal BOLD responses evoked by covert visual search suggest eye‐centred coding
Abstract Visual scenes explored covertly are initially represented in a retinal frame of reference (FOR). On the other hand, ‘later’ stages of the cortical network allocating spatial attention most probably use non‐retinal or non‐eye‐centred representations as they may ease the integration of different sensory modalities for the formation of supramodal representations of space. We tested if the cortical areas involved in shifting covert attention are based on eye‐centred or non‐eye‐centred coding by using functional magnetic resonance imaging. Subjects were scanned while detecting a target item (a regularly...

The seductive charm of fMRI
Neuroimaging is widely regarded as the key to understanding everything we do, but the authors of a controversial new book, Brainwashed, claim this approach is misguided and dangerousYou've seen the headlines: This is your brain on love. Or God. Or envy. Or happiness. And they're reliably accompanied by pictures of colour-drenched brains – scans capturing Buddhist monks meditating, addicts craving cocaine, and students choosing Coke over Pepsi. The media – and even some neuroscientists, it seems – love to invoke the neural foundations of human behaviour to explain everything from the Bernie Madoff financial fiasco to ...

Intensity-based image registration using scatter search
We present a novel intensity-based algorithm for medical image registration (IR).Methods and materials: The IR problem is formulated as a continuous optimization task, and our work focuses on the development of the optimization component. Our method is designed over an advanced scatter search template, and it uses a combination of restart and dynamic boundary mechanisms integrated within a multi-resolution strategy.Results: The experimental validation is performed over two datasets of human brain magnetic resonance imaging. The algorithm is evaluated in both a stand-alone registration application and an atlas-based segment...

Education and Hypnosis for Treatment of Functional Gastrointestinal Disorders (FGIDs) in Pediatrics.
Abstract FGIDs in children and adolescents (ROME III classification) have a significant impact on the daily functioning and quality of life. Often it is the pain that is one of the main contributors to the burden of functional dyspepsia, functional abdominal pain (syndrome), and irritable bowel syndrome. Current knowledge confirms that a number of integrated networks at cortical and subcortical sites are responsible for the experience of pain. From the work of Mayer and Tillisch (2011), mainly based on structural and functional magnetic resonance imaging and positron emission tomography, it has become clear that a...

Complicated abdominal pregnancy with placenta feeding off sacral plexus and subsequent multiple ectopic pregnancies during a 4-year follow-up: a case report
Conclusions Ectopic pregnancies should be identified early and evaluated for the etiology of the presentation. Rarely, an ectopic pregnancy implants at an extratubal location. Today, early intervention saves lives and reduces morbidity, but ectopic pregnancy still accounts for 4 to 10 % of pregnancy-related deaths and leads to a high incidence of ectopic site gestations in future pregnancies. Medical management has emerged as a safe alternative to surgery and holds promise for preservation of future fertility; however, surgery remains an acceptable modality. We found that careful and strategic choice of managem...

Association between Enlarged Axillary Lymph Nodes and Silicone Breast Implant Ruptures seen on Magnetic Resonance Imaging.
CONCLUSIONS: Enlarged axillary nodes were associated with ruptures in two groups of patients. This finding can guide clinical decisions when either enlarged nodes or ruptures are encountered in patients with silicone implants. The association between silicone lymphadenopathy and implant rupture raises concerns regarding the role of rupture in silicone-induced systemic disease. PMID: 28457073 [PubMed - in process]
