What Is Radiology and Imaging Technology?
Have you ever heard about Radiology and Imaging Technology? These are the diagnostic techniques being used widely in the medical diagnostic procedures. Radiology is the branch of medicine that uses radiant energy, usually X-rays or ultrasound waves to diagnose and treat diseases. The person who is specialised in radiology is known as ‘Radiologist’ who makes use of imaging technology for the purpose. For this, he must be qualified in the undergraduate degree with other courses along with some internship before starting practice.
Let’s know more about it in detail:
Types of Radiology
Radiology is broadly divided in two major areas depending upon the purpose of its use. These are diagnostic radiology and interventional radiology.
Health care professionals known as diagnostic radiologists examine internal structures of the body through this technique. It has its application in diagnosing the cause of symptoms or diseases like lung cancer, breast cancer by using radio images. Also, it is used to see how the body is responding to the relevant treatment.
The errors or discrepancies in the final reports can further be removed by using the CXR quality control tool. Use of such Al tools helps the radiologists to identify the errors in reports and improve the patient outcomes in return. Following are some technologies used in diagnostic radiology:
- Plain x-rays, chest x-ray is one of its common practices.
- Positron emission tomography, also known as PET imaging or PET scan. Sometimes when it is combined with CT, it is termed as PET-CT.
- Computerised axial tomography (CAT) or computed tomography (CT) scan.
- Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA)
- Nuclear medicine, that contains tests as a bone scan, thyroid scan, and thallium cardiac stress test.
Interventional radiology is used by doctors or physicians to help them proceed with multiple procedures and treatment options later on. Radiology techniques like CT scan, fluoroscopy, or MRI are performed when the doctors want to insert catheters and other tools in the body. For this, a small incision instead of a larger cut is made in the targeted area. There is no need for hospitalisation for this procedure, just a moderate sedation is enough to relax the patient.
Here are some common procedures being performed by the interventional radiologists:
- Cancer treatments including tumour embolization using chemoembolization or Y-90 radioembolization
- Angiography or angioplasty and stent placement
- Breast biopsy, guided either by stereotactic or ultrasound techniques
- Uterine artery embolization
- Embolization to control bleeding
- Tumour ablation by using radiofrequency ablation, cryoablation, or microwave ablation
- Vertebroplasty and kyphoplasty
- Venous access catheter placement, like ports and PICCs
- Needle biopsies of different organs, for instance, the lungs and thyroid gland
- Feeding tube placement
Radiology or medical imaging is now advancing and being used in most of the diagnostic operations. Not just diagnosis, it helps physicians to improve and evaluate their treatment ways during the course and after its accomplishment. Thus, radiologists have a major role in ensuring better patient outcomes by assisting the doctors in diagnosis.
