Summary
Diagnostic radiology examinations on pregnant patients result in low fetal radiation doses. These doses pose a negligible risk of deterministic effects or hereditary effects in descendants.
Area of Science:
- Radiology
- Medical Physics
- Radiation Biology
Background:
- Diagnostic radiology is frequently used, sometimes involving pregnant patients.
- Estimating fetal dose and risk is crucial in these scenarios.
Purpose of the Study:
- To investigate fetal radiation doses from diagnostic radiology examinations.
- To assess the associated risks of hereditary effects and childhood cancer.
Main Methods:
- Collected exposure techniques from 414 examinations involving 367 fetuses.
- Utilized the FetDoseV4 program for dose and risk estimations.
Main Results:
- Fetal radiation doses ranged from <0.001 to 21.9 mGy.
- Probability of hereditary effects ranged from <1 in 200,000,000 to 1 in 10,000.
- Risk of childhood cancer ranged from <1 in 12,500,000 to 1 in 500.
Conclusions:
- Properly conducted diagnostic radiology examinations result in fetal doses below deterministic effect thresholds.
- The risk of radiation-induced hereditary effects in descendants is negligible.

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
716
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...

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

02:59Biological Effects of Radiation
15.4K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

01:20Imaging Studies for Cardiovascular System III: X-Ray
684
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...

Description
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...

01:07Teratogenicity
4.2K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
