Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...

Imaging Studies for Cardiovascular System III: X-Ray

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...

Background:

Direct fluoroscopy is prevalent in Albania due to limited X-ray film availability, particularly for chest radiology.
Assessing radiation dose and associated risks is crucial for patient safety in medical imaging.

Purpose of the Study:

To quantify patient skin dose and effective dose for direct fluoroscopy units in Albania.
To compare radiation doses with established benchmarks and UK radiography practices.

Main Methods:

A Quality Assurance (QA) protocol assessed X-ray unit parameters (potential accuracy, half-value layer, output).
Organ-equivalent doses were measured using an anthropomorphic phantom and thermoluminescent dosimeters for chest fluoroscopy.
Dose data were normalized to specific beam parameters representing common techniques.

Main Results:

Effective doses ranged from 0.06 to 0.42 mSv for a 20-second PA chest fluoroscopy examination.
Mean effective dose was 0.22 mSv, approximately 13 times higher than UK film/screen radiography.
Entrance surface dose was 50 times greater than the EU reference level.

Conclusions:

Direct fluoroscopy in Albania delivers substantially higher radiation doses than recommended standards and UK practices.
Urgent optimization of X-ray equipment and protocols is needed to reduce patient radiation exposure.
Findings underscore the importance of regular quality assurance and dose monitoring in medical imaging settings.
