Summary
Radiation dose monitoring software effectively tracks high-dose procedures in interventional radiology (IR) and neuro-interventional radiology (NIR). Patient-reported radiation-induced tissue reactions were uncommon, with temporary skin/hair injuries in 10.2% of high-dose NIR cases.
Area of Science:
- Medical Physics
- Radiology
- Interventional Radiology
Background:
- Fluoroscopically guided interventional radiology (IR) and neuro-interventional radiology (NIR) procedures can involve significant radiation doses.
- Effective monitoring and clinical follow-up are crucial for managing potential radiation-induced tissue reactions.
Purpose of the Study:
- To assess the implementation of radiation dose monitoring software in IR and NIR procedures.
- To establish a process for clinical follow-up and documentation of high-dose cases.
- To quantify patient-reported radiation-induced tissue reactions.
Main Methods:
- Web-based radiation dose monitoring software was implemented to flag procedures with reference point air kerma (Ka,r) > 5000 mGy.
- A retrospective chart review was conducted for high-dose procedures over a 1-year period.
- Patient-reported tissue reactions were evaluated for all flagged cases.
Main Results:
- The software successfully transferred dose data for 93.9% of procedures.
- Ten of 368 IR procedures (2.7%) and 52 of 1025 NIR procedures (5.1%) exceeded 5000 mGy.
- Five of 49 NIR patients (10.2%) reported temporary skin/hair injuries; no reactions were reported in IR cases.
Conclusions:
- Radiation dose monitoring software can be successfully implemented in interventional radiology settings.
- Radiation-induced tissue reactions are relatively uncommon following fluoroscopically guided procedures.
- A systematic approach to monitoring and follow-up is effective in managing high-dose cases.

18.0K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:

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...

01:17Radiation: Applications
1.8K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
