Summary
This study evaluated radiation doses in adult diagnostic X-ray examinations. Patient doses were found to be significantly lower than national and European reference levels, emphasizing the need for increased awareness of radiation exposure and image quality.
Area of Science:
- Medical Physics
- Radiology
- Radiation Protection
Background:
- Diagnostic X-ray examinations are common procedures.
- Assessing patient radiation dose is crucial for radiation protection.
- Variability in radiation doses necessitates local and national surveys.
Purpose of the Study:
- To evaluate the radiation dose to adult patients undergoing common diagnostic X-ray examinations.
- To compare local dose data with national and European reference levels.
- To highlight the importance of patient dose awareness and optimization.
Main Methods:
- A survey was conducted on 1504 adult patients undergoing 7 common X-ray examinations.
- Patient entrance surface air kerma (ESAK) and effective dose (ED) were calculated.
- Dose values were compared with national reference levels and European data (DOSE DATAMED II).
Main Results:
- Mean and 75th percentile ESAK, Kerma Area Product (KAP), and ED values were determined for various X-ray projections.
- All measured dose values were significantly lower than national reference levels and European reported values.
- Specific mean values for ESAK ranged from 0.12 mGy (chest PA) to 5.74 mGy (lumbar spine LAT).
Conclusions:
- Patient radiation doses in this survey are below established reference levels.
- Patient dose surveys are vital for optimizing radiation protection.
- Increased awareness of radiation dose and image quality is necessary for patient safety.

01:15Drug Dosing: Geriatric Patients
274
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

01:21Drug Dosing: Obese Patients
265
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

26.2K
The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

46.8K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:

A loading dose is an essential pharmacological strategy to rapidly achieve the target plasma drug concentration necessary for an immediate therapeutic effect. This approach is especially critical for drugs characterized by slow absorption or extended half-lives, where delaying therapeutic plasma levels could compromise treatment outcomes. By administering a loading dose, clinicians ensure a prompt onset of drug action, even for agents with complex pharmacokinetic profiles.Achieving steady-state...
