What is fluoroscopy?
Fluoroscopy is a medical imaging technique that uses X-rays to obtain real-time moving images of the internal structures of the body. During a fluoroscopy procedure, an X-ray beam is passed through the body. The image is transmitted to a monitor so the movement of a body part or of an instrument or contrast agent (“X-ray dye“) through the body can be seen in detail. Fluoroscopy, as an imaging tool, enables physicians to look at many body systems, including the skeletal, digestive, urinary, respiratory, and reproductive systems.
Fluoroscopy may be performed to evaluate specific areas of the body, including the bones, muscles, and joints, as well as solid organs, such as the heart, lung, kidneys, gastrointestinal (GI) tract, blood vessels, and joints. Fluoroscopy is particularly useful for guiding medical procedures and surgeries, as it provides continuous, dynamic images that help healthcare providers monitor the progress of the procedure and make real-time adjustments.
Discovery Of Fluoroscopy.
The fluoroscopy was invented by Thomas A. Edition in 1896.

Risk of fluoroscopy.
Risk of fluoroscopy are given below:-
1. Ionizing Radiation Exposure:- Fluoroscopy uses X-rays, which are a form of ionizing radiation. Prolonged or repeated exposure to ionizing radiation can increase the risk of cellular damage, DNA mutations, and potential long-term health effects, such as cancer.
2. Cumulative Radiation Dose:- Some medical procedures may require prolonged or repeated fluoroscopic imaging, which can result in a cumulative radiation dose. This cumulative dose can be a concern for patients who undergo multiple procedures over time or healthcare professionals who frequently use fluoroscopy.
3. Radiation Risk to Pregnant Patients:- Pregnant women are particularly sensitive to radiation exposure because it can harm the developing fetus. Special precautions, such as shielding and minimizing radiation exposure, are taken when performing fluoroscopy on pregnant patients to protect both the mother and the unborn child.
4. Scattered Radiation:- X-rays used in fluoroscopy can scatter off the patient’s body and surrounding objects. Healthcare providers and other personnel in the room can be exposed to scattered radiation if not adequately protected, potentially increasing their radiation risk.
5. Skin Burns and Tissue Damage:- Prolonged exposure to the X-ray beam during fluoroscopy can lead to skin burns and damage to underlying tissues. This is more likely to occur in procedures where the X-ray source is positioned close to the patient’s skin.
6. Allergic Reactions to Contrast Agents:- Some fluoroscopic procedures involve the use of contrast agents, which can cause allergic reactions in a small percentage of patients. These reactions can range from mild skin rashes to severe, life-threatening anaphylaxis.
7. Infection Risk:- Invasive fluoroscopic procedures, such as catheterizations, may carry a risk of infection at the insertion site.
To mitigate these risks, healthcare professionals follow strict safety protocols when using fluoroscopy, including:
1. ALARA Principle:- ALARA stands for “As Low As Reasonably Achievable.” Healthcare providers aim to minimize radiation exposure to the lowest possible level while still obtaining the necessary diagnostic or interventional information.
2. Radiation Shielding:- Lead aprons, thyroid shields, and other protective equipment are worn by healthcare providers to reduce their exposure to scattered radiation.
3. Collimation and Dose Monitoring:- Collimating the X-ray beam to the area of interest and using dose monitoring systems help control and limit radiation exposure.
4. Patient Positioning:– Accurate positioning of the patient and the X-ray equipment ensures that only the necessary areas are exposed to radiation.
5. Pregnancy Screening:- Patients are screened for pregnancy before fluoroscopy procedures, and additional precautions are taken if necessary.
6. Informed Consent:- Patients are informed of the potential risks and benefits of fluoroscopy procedures and provide informed consent before undergoing them.
