Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

1.1K
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

411
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...

Teratogenicity01:07

Teratogenicity

4.0K
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...

Cancer Therapies

9.8K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Biological Effects of Radiation02:59

Biological Effects of Radiation

17.6K
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...

Isotopes and Radioisotopes01:28

Isotopes and Radioisotopes

11.0K
In the early 1900s, English chemist Frederick Soddy realized that an element could have atoms with different masses that were chemically indistinguishable. These different types are called isotopes — atoms of the same element that differ in mass. Isotopes differ in mass because they have different numbers of neutrons but are chemically identical because they have the same number of protons. Soddy was awarded the Nobel Prize in Chemistry in 1921 for this discovery.
An isotope containing...

Summary
This summary is machine-generated.

Radiotherapy during pregnancy is rare but carries risks to the fetus, depending on gestational age. Supradiaphragmatic radiation may be safe, but subdiaphragmatic radiation warrants pregnancy termination, with dose monitoring crucial.

Area of Science:

  • Oncology
  • Radiation Oncology
  • Maternal-Fetal Medicine

Background:

  • Cancer during pregnancy is infrequent, occurring in about 1 in 1000 pregnancies.
  • Fetal risks from radiation depend on gestational age, including malformations, microcephaly, and potential radiation-induced cancer.
  • Existing guidelines require updates for managing radiotherapy in pregnant patients.

Purpose of the Study:

  • To present updated recommendations from the French Society for Radiation Oncology (SFRO) on radiotherapy use during pregnancy.
  • To outline risk stratification and management strategies based on irradiation location and gestational age.
  • To emphasize dose monitoring and preferred radiotherapy techniques.

Main Methods:

  • Review and synthesis of current evidence and expert consensus on radiotherapy and pregnancy.
  • Risk assessment based on embryo/fetal exposure levels and gestational age.
  • Evaluation of different radiotherapy techniques, including conformational and intensity-modulated radiotherapy.

Main Results:

  • Supradiaphragmatic irradiation may be performed in pregnant women with minimal fetal risk.
  • Subdiaphragmatic irradiation necessitates proposing therapeutic termination of pregnancy due to significant fetal risk.
  • Phantom dose estimation and in vivo measurement are recommended when radiotherapy is administered.
  • Conformational radiotherapy is generally preferred for lower fetal dose, with exceptions for specific tumor sites.

Conclusions:

  • Updated SFRO recommendations provide a framework for managing radiotherapy in pregnant patients.
  • Risk-benefit assessment is critical, guiding decisions on treatment continuation or termination.
  • Precise dose monitoring and technique selection are paramount to minimize fetal exposure.
