Medical imaging is diverse, making it possible to identify and treat a variety of injuries and health problems. But are all radiography applications the same or similar?
In the radiography industry, varied methodologies help professionals perform important diagnostic tasks, as well as support some treatment options. The distinctions between these two medical specialities mean that unique radiology techniques are often required to provide positive patient outcomes.
If you’ve ever wondered about the key differences between diagnostic and interventional radiology, this guide is for you. Here are the basics that you need to know.
Diagnostic radiology is used as the foundation for detecting diseases, using external radiation to safely produce detailed images of bodily systems and structures.
Often, diagnostic radiology techniques include the use of radiation-emitting X-rays or ultrasonographic devices. Radionuclides and radiofrequency electromagnetic radiation may also be applied.
In most cases, diagnostic radiology is non-invasive and able to be performed without any incisions or surgical interventions. However, this can vary depending on what diagnostic functions are required.
Sometimes, diagnostic radiology may include minimally invasive procedures. Diagnostic techniques might also be used as part of some surgeries or medical interventions. Above all, diagnostic imaging is designed to support the diagnosis of disease.
Interventional radiology is used as part of the medical treatment process. This form of radiology uses high-quality imaging and can support a range of medical interventions.
Generally, interventional radiology includes minimally invasive procedures, often performed in a hospital or specialised clinic. Electromagnetic or radiation technologies are applied, using tiny instruments to navigate blood vessels and reach treatment sites.
While interventional radiology applications can vary, this form of radiography is often used to help treat cancer, lymphatic diseases, and vascular abnormalities. Many other health conditions can also benefit from radiological intervention.
Interventional radiology may be used alongside other treatment options. In simple terms, interventional radiology is a radiological approach to the treatment of illness or disease.
While radiographers can be trained to work in both diagnostic and interventional capacities, these are two distinct skill sets. Each discipline has its own unique features and requirements - these are some of the main differences between them.
The most obvious difference between diagnostic and interventional radiology is the purpose of radiology.
Diagnostic radiology focuses on identifying problems and facilitating the diagnosis of disease. This type of radiology examines bodily systems to identify any problems and determine the cause.
Conversely, interventional radiology occurs after a disease has already been diagnosed and is designed to be part of a comprehensive treatment plan. This type of radiology helps to treat known symptoms and diseases.
Another key difference between the two main radiological branches is the procedural approach each discipline entails.
Diagnostic radiology is usually performed as a non-invasive procedure and can be offered at most radiography clinics. For diagnostic purposes, surgical intervention is usually not required.
Interventional radiology often includes minimally invasive medical procedures, which could lead to side effects. For this reason, interventional radiology is usually provided in a specialised clinic or hospital setting.
Finally, diagnostic and interventional radiology often use different radiology types and techniques, in line with their differing goals and methods.
Diagnostic radiology may include ultrasonography, radionuclides, X-ray radiation, or electromagnetic radiation. These techniques each offer unique diagnostic capabilities.
Interventional radiology is usually less diverse due to its more invasive nature. Typically, interventional procedures include radiation or electromagnetic applications.
Knowing the differences between diagnostic and interventional radiology can help you develop a clear understanding of the medical imaging process. If you’re undergoing radiography, this can help to reduce feelings of uncertainty and anxiety by helping you fully comprehend your medical needs.
Additionally, learning more about different radiological techniques and approaches can help you choose the right diagnostic and treatment options. With a good understanding of how medical imaging works, you can make informed decisions that benefit your long-term health and well-being.
