Valid Exposure Protocols Needed in Magnetic Resonance Imaging Genotoxic Research.

Several in vitro and in vivo studies have investigated if a magnetic resonance imaging (MRI) examination can cause DNA damage in human blood cells. However, the electromagnetic field (EMF) exposure that the cells received in the MR scanner was not sufficiently described. The first studies looking into this could be regarded as hypothesis-generating studies.

EMF exposure variation among MRI sequences from pediatric examination protocols.

The magnetic resonance imaging (MRI) exposure environment is unique due to the mixture and intensity of magnetic fields involved. Current safety regulations are based on well-known acute effects of heating and neuroexcitation while the scientific grounds for possible long-term effects from MRI exposure are lacking. Epidemiological research requires careful exposure characterization, and as a first step toward improved exposure assessment we set out to characterize the MRI-patient exposure environment.

Assessing Exposures to Magnetic Resonance Imaging's Complex Mixture of Magnetic Fields for , and Epidemiologic Studies of Health Effects for Staff and Patients.

A complex mixture of electromagnetic fields is used in magnetic resonance imaging (MRI): static, low-frequency, and radio frequency magnetic fields. Commonly, the static magnetic field ranges from one to three Tesla. The low-frequency field can reach several millitesla and with a time derivative of the order of some Tesla per second.

Trunk sway in idiopathic normal pressure hydrocephalus-Quantitative assessment in clinical practice.

Background: In diagnosis and treatment of patients with idiopathic normal pressure hydrocephalus (iNPH), there is need for clinically applicable, quantitative assessment of balance and gait. Using a body-worn gyroscopic system, the aim of this study was to assess postural stability of iNPH patients in standing, walking and during sensory deprivation before and after cerebrospinal fluid (CSF) drainage and surgery. A comparison was performed between healthy elderly (HE) and patients with various types of hydrocephalus (ventriculomegaly (VM)).

Exposure to the magnetic field from an induction loop pad for a hearing aid system.

As a case study we have measured the magnetic field from an induction loop pad designed for hearing aid assistance. The magnitude of the field was high, although well below international guidelines. We recorded values up to 70% of the recommended standard in some instances.

Interdisciplinary team training identifies discrepancies in institutional policies and practices.

The objective of this study was to evaluate the impact of an interdisciplinary team-training program in obstetric emergencies on identifying unsupportive institutional policies and systems-based practices. We implemented a qualitative study design with a purposive sample of interdisciplinary physicians, nurses, and ancillary allied health professionals from 4 specialties (n = 79) to conduct a 6-month, weekly simulation-based intervention for managing obstetric emergencies. Debriefing focused on identifying discrepancies between clinical practice and institutional policies.
