Researchers are increasingly using big data for interventional radiology (IR) studies. This review guides IR researchers on selecting and using public databases effectively for real-world evidence generation.
Area of Science:
- Interventional Radiology Research
- Health Services Research
- Big Data Analytics
Background:
- Observational research using publicly available big data is expanding in interventional radiology (IR).
- These large datasets offer valuable insights into real-world patient care and IR procedure effectiveness.
- However, understanding the strengths and limitations of these complex data sources is crucial to avoid erroneous conclusions.
Purpose of the Study:
- To review commonly used public databases for IR research.
- To highlight the strengths and limitations of these databases.
- To provide recommendations for the scientifically rigorous use of big data in IR.
Main Methods:
- Literature review of IR research utilizing publicly available big data.
- Analysis of common databases, their characteristics, and application in IR studies.
- Summary of methodological best practices for observational research with large datasets.
Main Results:
- Identification of key public databases relevant to interventional radiology.
- Discussion of the inherent strengths (e.g., real-world insights) and weaknesses (e.g., complex sampling) of big data.
- Presentation of best practices for planning and executing observational IR research.
Conclusions:
- Publicly available big data are essential for advancing interventional radiology research.
- Careful consideration of database strengths, limitations, and methodological best practices is vital for accurate real-world evidence.
- This review provides a framework for researchers to effectively leverage big data in IR.

Radiological Investigation I: X-ray and CT
Radiological Investigation III: Pulmonary Angiogram and 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...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
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...

Imaging Studies for Cardiovascular System III: X-Ray
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...
Observational Studies
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...
