Diagnostic reference levels help optimize radiation dose during interventional procedures. This review analyzes their establishment and application to guide China
Area of Science:
- Medical Imaging
- Radiation Protection
- Radiology
Context:
- Interventional procedures expose patients to X-rays.
- Optimizing radiation dose is crucial for patient safety.
- Diagnostic reference levels (DRLs) are key to dose management.
Purpose:
- To review the definition, establishment, and application of DRLs.
- To analyze factors influencing DRL variations across countries.
- To provide a basis for establishing DRLs in China.
Summary:
- DRLs are essential for optimizing radiation dose in interventional radiology.
- International variations in DRL indicators necessitate a review.
- This study retrospectively analyzes DRLs to inform Chinese guidelines.
Impact:
- Facilitates the establishment of standardized DRLs in China.
- Aims to reduce radiation hazards in interventional procedures.
- Contributes to global understanding of DRL implementation in radiology.

Radiological Investigation I: X-ray and CT
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...
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...
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...
