Radiology is a branch of medical science, which uses imaging to treat and diagnose diseases inside our body.It   plays an important role in the diagnosis of various health conditions, like fractured bones, cancers, brain injury, clotted arteries, fetus scanning, pulmonary conditions and  much more. It is a fairly new field as it was onlydiscovered in the nineteenth century, but despite that from just being a tool to find out about broken bones and lung patches it has seen major technological advances. Radiology gains relevance in the context of diagnosis and becomes the first step towards treatment and general health care.

The radiologists read the images and give a report of their findings and impressions, which is later submitted to the doctor for proper line of treatment to be taken.

Various kinds of imaging techniques are used by the radiologists, which can easily diagnose the cause of the symptoms and monitor how well the body is responding to treatment. Some of these imaging techniques used are the following:

Computed Tomography:

It is popularly known as CT scan. CT scans have revolutionized diagnostic radiology by providing Clinicians with images of real three-dimensional anatomic structures. This has made it the first choice in diagnosing some life threatening diseases like cerebral hemorrhage, pulmonary embolism, aortic dissection (tearing of the aortic wall), appendicitis, diverticulitis, and obstructing kidney stones. This technique is continually advancing with faster scanning times and improved resolution of the images, which have considerably increased the accuracy and usefulness of CT scanning.


Ultrasound scan uses high-frequency sound waves to look at soft tissue structures such as internal organs, blood vessels tendons, muscles, joints, etc. This imaging technique does not use ionized radiation to generate images. It is areasonably safer technique and so extensively used on pregnant women to find about the health and general well-being of the fetus.


Magnetic resonance imaging uses radio waves, magnetism, computer etc. to produces images of body structures. MRI has the ability to produce images in different planes like axial, sagittal, coronal and oblique planes. So the physicians prefer an MRIscan of the brain, musculoskeletal system, and spine etc.The only disadvantage from patient’s point of view is, that the patient has to hold still for long periods in a noisy, cramped space while the imaging is performed. Sometimes the MRI exam has to be terminated for patients suffering with severe claustrophobia.

 Nuclear Medicine:

Nuclear medicine is used to diagnose and determine the severity of disease like cancer, neurological disorders, endocrine, heart disease, gastrointestinal etc., this branch of medical imaging uses a small amount of radioactive material.

Interventional Radiology:

These are invasive procedures, whichare generally performed for diagnosis like angiogram or for treatment process like angioplasty. Interventional radiology is done with minimum invasive technique possible. It’s generally performed on patients with little or no sedation at all.

We cannot deny the important place that Radiology has been given in recent years in the medical field. It has basically become the most preferred method for accurate and timely diagnosis and the treatment of patients which results in less mortality and morbidity of disease.
