Abstract:
The three general principles of the International Commission on Radiological Protection (ICRP) are first recalled: (1) justification, (2) ALARA, (3) the dose limits. The dose limits to be followed, at present, in Belgium are given for the occupational exposure, the occupational exposure of women (pregnant and not), the exposure of the public. The possible modification of the dose limits by the ICRP is a near future is discussed. The present belgian regulations are reviewed as far as the equipment and the buildings are concerned, as well as for the personal dosimeters and the medical supervision. Finally, the doses delivered to the patients, at different organs, during dental radiological examinations are recalled, e.g. the doses at the skin, the thyroid, the gonads, the eyes, the pituitary gland. The interest of shielding the thyroid and the abdomen is discussed.

X-ray Imaging
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...

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
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...
