What is Radiology

Interpretation of the picture shown in an x-ray photograph is a tedious task. In order to rightly understand the x-ray pictures or the scanned photographs in the thin films, one has to undergo extensive training for a period of about 5 to 6 years under this specialization. Radiology and radio graphics are quite essential fields of medicine that are constantly improvised in the recent past with the introduction of sophisticated machines and technology. Digital radiology is the latest in the trend and it allows radiologist to analyze concepts quite easily with more precision and accuracy. Even a layman could understand the internal structure and alignment better while trying to interpret these digital x-rays. The current research in the field of radiology is in this subject of digital radiology.

Fundamentally, it is just a process of incidenting light rays onto the human body. The beam that is made to incident on the human body could be x-rays or any other kind of radiation in order to reflect the obtrusions inside very clearly in the form of a scan in a thin film called as the x-ray sheet. While exposed to this kind of higher order wavelength of radiation on a continuous basis or more frequently, the bodily parts could get affected to a certain extent. There are possibilities of catching up with cancer in some cases due to exposure of such radiation. In order to avoid this, there are alternative methods that were introduced in the field radiology in the recent past. These are the MR scans and the UV scans. The ultra violet rays are used instead of the x-rays.

Radiology society of North America published two journals in this field. They are the radiographic and the radiology. These journals give updated information about the latest happenings in the field of radiology. In fact, the impact factor of these journals is very high and they are considered to be completely content oriented in their publications. Radiologists from all over the world do follow this ongoing research content to keep abreast of the latest trends in the field of radiology. Moreover, radiology is inevitable part of many other fields of medicine. Whether it is oncology or even diabetes research, the involvement of radiology in the modern trends of research are quite significant. The need for the radiographic experts to demonstrate and clarify the nature of the subject prototypes and models in the experiment is quite crucial though.

The number of radiologists all over the world is quite low though. More and more professionals are needed in order to meet the extensive demand in the world market. The present day scenario in the United States of America is that most of the top notch health centers have too many positions vacant for the post of a good experienced radiologist. The lucrative pay packets are quite attractive but yet the numbers of experts that emerge in this lucrative field are scarce. Youngsters should target this field to obtain specialization to scale remarkable heights in their career in a shortest span of time.

Radiology is a branch of science which is used to view the organs inside the human body. It is the study of images of human body. Some widely used techniques of radiology are:

  • X-Rays: X-rays are used to produce the still images of bones. It is used to diagnose bone cancer, bone injuries etc.
  • Ultrasound: this procedure produces moving pictures of the organ of the body to be examined. It is mostly used to scan the abdominal area. It is very helpful for pregnant woman as using this technique, doctors can know about the growth of the baby.
  • MRI (Magnetic Resonance Imaging): MRI is a powerful tool in diagnosing the problems related to the brain. It is very helpful in the field of neurology for doctors. An advantage of MRI is its capability to produce images in axial, coronal, sagittal and multiple oblique planes with equal ease. With the advancement in technology, it also has the ability to produce 3D images. It can be used to know the problems related to brain, spine bone etc.
  • PET (Positron Emission Tomography): PET falls under nuclear medicine. In this type of scanning, a radioactive biologically active substance, mostly Fluorine-18 Flourodeoxyglucose, is injected into the patient’s body and then the radiations emitted by the patient’s body are used to produce the multi-planar images of body. It is very helpful in diagnosing cancer. It is a more accurate procedure of diagnosing diseases.
  • CT (Computed Tomography): it is also like PET. It is also a more accurate method of diagnosing the diseases.

The person who performs all these tests on patient are called radiologists. Radiologists are the physicians who are trained in performing all these exams on patient’s body and also trained in the interpretation of the images produced through these procedures. A radiologists should be trained enough to make an accurate interpretation of the images produced. Only then it will help in accurate diagnosis of the disease and only then it will be helpful in treating the disease. If a wrong interpretation will be made by him, then it will lead to the wrong diagnosis and as a result of it, wrong treatment will be given to the patient, so correct results are very important. In order to know the results, patients will have to wait for some time. If a radiologist is facing problem in producing the correct results of the exam, then he/she should consult the other doctors instead of producing a wrong result. The radiologists should make the patient comfortable and calm before performing the exam. Radiology has some side effects too. The radiations emitted can be dangerous but only if these tests are performed frequently.
