Summary
Pediatric whole-body MRI is a growing imaging tool, but practices vary in its use and protocols. This survey reveals common indications and sequences, highlighting a need for standardization in pediatric radiology.
Area of Science:
- Radiology
- Pediatric Imaging
- Magnetic Resonance Imaging
Background:
- Whole-body magnetic resonance imaging (MRI) is an increasingly important imaging tool for pediatric patients.
- Significant variability exists in how whole-body MRI is utilized and performed across different radiology practices.
Purpose of the Study:
- To understand technical and utilization practices of pediatric whole-body MRI in North America.
- To explore common indications, referral patterns, and technical protocols for pediatric whole-body MRI.
Main Methods:
- A 19-question survey was distributed to the Society for Pediatric Radiology membership in 2016.
- The survey collected data on practice type, modality preferences, MRI field strength, sequence selection, and billing.
Main Results:
- 62 responses from 471 physicians indicated whole-body MRI is preferred for neurofibromatosis type 1, CRMO, cancer predisposition syndromes, vasculopathies, and disseminated infections.
- Commonly used sequences include coronal STIR, coronal T1, and axial DWI, with no preference for 1.5-T or 3-T systems.
- Variability was observed in billing practices, with most using chest/abdomen/pelvis or unlisted MRI codes.
Conclusions:
- Pediatric radiologists utilize whole-body MRI for diverse indications in pediatric imaging.
- Survey results highlight variability in exam utilization and technical performance, suggesting areas for standardization.

01:10Electrical Current
7.2K
Electrical current is defined as the rate at which charge flows. When there is a large current present, such as that used to run a refrigerator, a large amount of charge moves through the wire in a small amount of time. If the current is small, such as that used to operate a handheld calculator, a small amount of charge moves through the circuit over a long period of time. The SI unit for current is the ampere (A), named for the French physicist André-Marie Ampère (1775–1836).

01:26Pharmacokinetics in Pediatric Patients: Drug Excretion
274
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

01:16Characteristics of Practical Op Amps

A difference amplifier, a crucial component in numerous electronic devices, ideally amplifies only the difference-mode signal, which is the difference between two input signals. However, in practical circuits, the output voltage depends on both the differential gain and the common-mode gain.
The ratio of differential gain to the common-mode gain is defined as the common-mode rejection ratio (CMRR). This ratio quantifies the ability of operational amplifiers (op-amps) to reject common-mode...

Theories play an essential role in organizing patient care. Theories refer to a proposed or followed belief, policy, or procedure that is the basis for action. Nursing theories are knowledge-based concepts that guide nurses' actions, influence nursing education and practice, and allow nurses to care for their patients.
Theories provide a perspective to assess patients' conditions and organize data and methods. They also assist in analyzing and interpreting information. They represent a...

01:28Equivalent Circuits for Practical Transformers
1.4K
The practical equivalent circuits of single-phase two-winding transformers exhibit significant deviations from their idealized versions due to the inherent properties of winding resistance and finite core permeability. These properties result in real and reactive power losses, affecting the transformer's performance. Understanding these deviations is crucial for designing more efficient transformers.
In a practical transformer, each winding exhibits resistance and leakage reactance. The...

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...
