Abstract

Insights

Prostate multiparametric 1.5-T MRI is safe for patients with cardiac implantable electronic devices (CIEDs). Image quality is maintained, with no serious adverse effects and acceptable signal-to-noise ratio.

Area of Science:

  • Radiology
  • Medical Imaging
  • Cardiovascular Devices

Background:

  • Cardiac implantable electronic devices (CIEDs) can pose safety and image quality challenges during MRI.
  • Multiparametric MRI (mpMRI) is crucial for prostate cancer diagnosis and management.

Purpose of the Study:

  • To evaluate the patient safety and diagnostic image quality of 1.5-T prostate mpMRI in patients with CIEDs.

Main Methods:

  • Retrospective analysis of 1.5-T prostate mpMRI in patients with CIEDs (study group) and without (control group).
  • Assessed clinical safety, specific absorption rate (SAR), signal-to-noise ratio (SNR), and image quality/artifacts.
  • Two independent readers rated image quality on a 5-point scale.

Main Results:

  • No serious device-related adverse events occurred in the CIED group (0/28 examinations).
  • Whole-body SAR remained below 1.5 W/kg.
  • While SNR was slightly lower in the CIED group, image quality and artifact perception were not significantly different from controls (rated above average).

Conclusions:

  • 1.5-T prostate mpMRI can be safely performed in selected patients with CIEDs under controlled conditions.
  • Applicable image quality is achievable, maintaining safety and diagnostic utility.
  • Adherence to SAR limits (<1.5 W/kg) is essential for safe scanning.

Survey Safety01:28

Survey Safety

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Household Wiring And Electrical Safety

Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...

Quality Control

Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Quality Assurance01:19

Quality Assurance

Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

Quality of Water

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
