Alteration of flux density of highly coercive SmCo magnets used in prosthodontics and epithetics in 1.5  T and 3 T MRI.

CONCLUSION: Highly coercive SmCo magnets can remain in situ during a 1.5 T MRI scan unless the resulting artifacts are diagnostically relevant. Exposure to the 3 T main field in antiparallel position may result in a complete loss of the adhesive force. In this case the magnets should be remagnetized by the manufacturer. Inclination or reclination of the head reinforces the effect of the main field. PMID: 31214744 [PubMed - as supplied by publisher]

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...

AbstractWe have read the article entitled “Laparoscopic treatment of endometriosis and predictors of major complications: a retrospective cohort study” by Clarket al with great interest [1]. It has been reported that major complications following laparoscopic treatment of endometriosis are infrequent and difficult to predict by patient characteristics and preoperative imaging (magnetic resonance imaging (MRI) or ultrasound (US)).

Conclusions: The present study seeks to provide new insight in the pathophysiological mechanisms linking reduced kidney function to cardiovascular disease. In addition, we aim to enlighten predictors of adverse cardiovascular outcome in living kidney donors. The study is registered at Clinical-Trials.gov (identifier: NCT03729557).

In 1983, a health professional in her 30s walked into my office and said, “I’ve been healthy all of my life. A year ago, I came down with some kind of virus — sore throat, aching muscles, swollen lymph glands, fever. My fatigue was so bad I was in bed for nearly a week. Many of the symptoms gradually improved, but the terrible fatigue and difficulty thinking have not gotten better. They’re so bad I can’t fulfill my responsibilities at home or at work. This illness is affecting my brain, stealing my energy, and affecting my immune system. It’s keeping me from realizing my dreams.” T...

As conventional experimental tasks lack this type of everyday complexity, we administered a film-based multi-talker condition with auditory distractors in the background. ADHD-related aberrant brain r...

If you want residents to moan, start out the conversation with “when I was a resident….” Well, when I was a resident, computed tomography (CT) scans had just been introduced into the hospital, ultrasound was a rarely used procedure, and magnetic resonance imaging and positron emission tomography were still in the future. We did tomograms, pyelograms, veno grams, and various scans of the spleen, liver, and brain. The imaging options available today are overwhelming. Three-dimensional reproductions of any part of the body; bedside ultrasounds of the brain, heart, abdomen, and pelvis; and scans that show fu...

Cognitive impairment is a common feature in Parkinson's disease (PD) and other α-synucleinopathies as 80% of PD patients develop dementia within 20 years. Early cognitive changes in PD patients present as a dysexecutive syndrome, broadly characterized as a disruption of the fronto-striatal dopamine network. Cognitive deficits in other domains (recognition memory, attention processes and visuospatial abilities) become apparent with the progression of PD and development of dementia. In dementia with Lewy bodies (DLB) the cognitive impairment develops early or even precedes parkinsonism and it is more pronounced in visu...

Authors: Gulak MA, Bornais C, Shin S, Murphy L, Smylie J, Pantarotto JR, Fung-Kee-Fung M, Maziak DE Abstract Background: Patients with lung cancer often experience stressful delays throughout the diagnostic phase of care. To address that situation, our multidisciplinary team created a "Navigation Day," during which patients partake in a single-day visit that comprises nurse-led teaching, social work, smoking cessation counselling, symptom control, and dedicated test slots for integrated positron-emission tomography and computed tomography (pet/ct), pulmonary function tests (pfts), and magnetic resonance i...

ConclusionMesenteric cysts represent a rare cause of intra-abdominal mass. Owing to low prevalence, literature is limited as is guidance on management. Careful pre-operative planning is essential so as to avoid operative complications. Imaging such as USS is of great importance; however Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) may be of more benefit, owing to the complex anatomical relations within which mesenteric cysts can present. Surgical excision is widely reported as the surgical treatment of choice for symptomatic cysts
