Radiology services refer to those services and facilities that are used during the radiotherapy treatment procedure. These services include a range of medical treatments that are performed during diagnosis. The radiology services can be classified into technical support, expert support and external patient care amenities. For the best possible services, hospitals have to be equipped with dedicated radiology physicians, technical and supportive staff, advanced equipments, and optimal patient care and diagnostic assistance.
Under the diagnosis procedures, physicians consider some radiological tests, such as computed tomography (CT) scanning, magnetic resonance imaging (MRI), projection radiography, fluoroscopy, nuclear medicine, ultrasound, etc. These are the essential tests required for this minimally invasive therapy. To perform CT scan, doctor uses X-rays along with computing algorithms to view the image of the body. It is a kind of medical imaging method created by computer processing. In this method a digital geometry procession is used to generate a three dimensional image of the inside of the body. On the other hand, an MRI scanner produces same picture without using X-rays. In radiology it is used to visualize detailed internal structure and limited function of the body.
The MRI technology uses a powerful magnetic field with radio frequencies by which detailed pictures of organs, bones, tissues and other internal body structure can be accessed without using ionizing radiation. MRI scan services are used to produce the highest quality images of the soft tissues. This technology is beneficial for the imaging of the brain, breast cancer, spine, and musculosketal system. Such detailed pictures enable physicians to evaluate parts of the body and certain types of diseases that may not be assessed in other methods. Another important radiological service is ultrasound or ultrasonography. It is an effective treatment modality that can visualize various organs systems with the help of high frequency sound waves. This technology is commonly used in to examine veins, arteries, abdomen, and female reproductive system.
Some other specific radiological services are pediatric radiology, cardiovascular imaging, Central DEXA (Dual Energy X-ray Absorptiometry), etc. Overall, there are large services under radiology treatment through which patient can effectively diagnose cancer and other fatal diseases.
