Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

645
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

625
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Radiological Investigation I: X-ray and CT

1.6K
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Drug Dosing: Infants and Children

769
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Pharmacokinetics in Pediatric Patients: Drug Excretion

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...

Area of Science:

  • Medical Imaging
  • Pediatric Radiology
  • Radiation Safety

Background:

  • Pediatric diagnostic fluoroscopy involves significant radiation exposure.
  • Effective dose reduction strategies are crucial for patient safety.

Purpose of the Study:

  • To evaluate radiation doses in pediatric fluoroscopy.
  • To determine the impact of dose tracking and reduction training on radiation use.

Main Methods:

  • Collected fluoroscopy time and dose area product (DAP) for upper GIs, VCUGs, and BEs.
  • Implemented a 1-hour training session on radiation dose reduction.
  • Analyzed pre- and post-training data using normalized DAP and Wilcoxon testing.

Main Results:

  • A statistically significant decrease in median normalized DAP was observed post-training for all procedures.
  • Normalized DAP decreased by nearly 50% across upper GIs, VCUGs, and BEs.
  • No significant changes in patient age, examination types, or overall fluoroscopy time were noted.

Conclusions:

  • Radiation dose tracking with feedback and targeted training effectively reduces radiation dose in pediatric fluoroscopy.
  • The combined approach achieved an approximate 50% reduction in radiation dose.
  • This highlights the efficacy of implementing such programs in clinical practice.
