Summary
Radiation exposure during fluoroscopy-guided interventional procedures varies significantly with imaging angles. Interventional radiologists face higher radiation levels, emphasizing the need for awareness and protective measures.
Area of Science:
- Medical Physics
- Radiology
- Radiation Safety
Background:
- Fluoroscopy-guided interventional (FGI) procedures involve significant radiation exposure.
- Quantifying scattered radiation is crucial for staff safety and optimizing procedures.
Purpose of the Study:
- To quantify scattered radiation levels at various locations during FGI procedures.
- To assess radiation exposure differences based on tube angulation and staff position.
Main Methods:
- Utilized nanoDot optically stimulated luminescence dosemeters to measure radiation.
- Measured scattered radiation across different patient table locations and imaging angles.
- Analyzed radiation spectrum distribution for various tube angulations.
Main Results:
- Radiation spectrum showed a single peak distribution across all angulations.
- Left anterior oblique 90° resulted in the highest peak distribution (28.65 mSv/h).
- Interventional radiologists consistently experienced higher radiation levels than other staff.
Conclusions:
- Radiation doses vary significantly with imaging angles and proximity to the patient.
- Understanding radiation exposure patterns is vital for mitigating risks to healthcare professionals.
- Optimized staff positioning and protective strategies are essential during FGI procedures.

428
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...

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...

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...
