Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

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 the...
X-ray Imaging01:24

X-ray Imaging

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 X-rays, and by 1900, X-ray was widely...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Drug Dosing: Infants and Children

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

Imaging Studies for Cardiovascular System III: X-Ray

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...

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Area of Science:

  • Medical Imaging
  • Radiological Physics
  • Neonatal Care

Background:

  • Neonates in special care units often require numerous radiographs for serious conditions.
  • Increased radiosensitivity and longer life expectancy in neonates heighten the risk of radiation-induced cancer.
  • Minimizing radiation dose while maintaining diagnostic image quality is essential in neonatal radiography.

Purpose of the Study:

  • To conduct an optimization study on radiation dose and image quality in neonatal radiography.
  • To evaluate the impact of different exposure parameters on dose and image quality.
  • To establish evidence-based protocols for neonatal radiography.

Main Methods:

  • Categorized 378 neonates into four birthweight groups.
  • Recorded exposure parameters, estimated Entrance Surface Dose (ESD), and measured Dose-Area Product (DAP).
  • Assessed image quality using a five-grade scale based on anatomical feature and catheter visibility.

Main Results:

  • Entrance Surface Dose (ESD) and Dose-Area Product (DAP) values showed wide variations, increasing with neonatal weight.
  • Diagnostic image quality was achievable with both low and high tube voltage techniques.
  • High tube voltage techniques resulted in reduced ESDs and were generally in line with recommended reference levels.

Conclusions:

  • High tube voltage techniques offer potential for further dose reduction in neonatal radiography without compromising image quality.
  • Establishing standardized examination protocols tailored to neonatal weight is recommended.
  • Optimized radiation protocols are vital for minimizing long-term risks in neonates.
