X-rays - Types, Risks and Preparation

X-ray Procedures Explained: Types, Risks, and How to Prepare

X-rays provide doctors with a great diagnostic tool to depict the contents of the body cavity in a completely non-invasive manner.

If patients can be enlightened a bit regarding the types of X-rays, the risks involved, and the type of preparation required for such procedures, they can be a little more relaxed.

Types of X-rays

1. Standard X-rays

Chest X-rays: They are used to examine the lungs, heart, and chest wall. They are carried out to diagnose various diseases that range from pneumonia, heart failure, and lung cancer.

Bone X-rays: They are done to find reasons for fractures, dislocations, or deforming changes in the bones. They mostly include examinations of arms, legs, and spine areas.

2. Computed Tomography (CT) Scans

Stitching together several hundred X-ray images exposed on all sides gives cross-sectional pictures of the body. Most appropriate for the study of bones, blood vessels, and soft tissues in exquisite detail.

3. Fluoroscopy 

Representing a moving image of the inside of the body in real-time. It is usually used during diagnostic tests, such as when swallowing barium or during cardiac catheterization.

4. Mammography

A special kind of X-ray used in the imaging of breasts. Mainly used for early breast cancer detection.

5. Dental X-rays

Visualize teeth and jaw structures. The diagnostic tool assists in cavities, gum diseases, and other dental problems.

Risks Associated with X-rays

Even though X-rays are considered relatively safe, they have some risks associated, mainly due to exposure to ionizing radiation. The major risks include:

1. Radiation Exposure - Continuous exposure to X-rays raises the risk of developing cancer after a long time. The risk is still higher for children and pregnant women since their bodies are more susceptible to the radiation.

2. Allergic Reactions  - Some X-ray procedures use contrast. These can cause allergic reactions in some people where the dyes are used. Difficulty breathing is one of the signs and symptoms, though it's a very serious reaction. Other patients may just experience itching or a rash.

Preparation for X-rays

Such proper preparation can facilitate the smooth conduct of an X-ray procedure with accurate results. The following steps are of a general nature and are to be adhered to:

1. Inform Your Doctor

•  Be sure to inform your doctor if you think you may be pregnant or if you are nursing. This is because the fetus is susceptible to damage from X-rays as it grows. Also, inform your doctor of any allergies you may have, especially those to contrast agents.

2. Remove Metal Objects

• Any metal objects—that is, jewellery, eyeglasses, clothing with metal zippers, or buttons will shadow the X-ray image, so you might be asked to remove these before the procedure.

3. Fasting and Special Instructions

•  With some kinds of X-rays, such as those of the gastrointestinal tract, you might need to fast or be on a special diet. Your doctor will instruct you as to what exactly to do prior to any type of test, depending on the kind of X-ray imaging that will be performed on you.

4. Contrast X-rays Need Special Instructions

• If your X-ray requires the use of a contrast agent, your healthcare provider may give you special preparation instructions, making sure that you have enough liquids or avoid some medications.

Summary

It is, however, a very vital diagnostic tool that provides for early identification and management of many conditions. Knowing the various types of X-rays, risks associated with them, and how to get ready for the test can greatly make the process of diagnosis easy and safe. Consult your doctor about any advice or instructions in regard to your individual case.
