Magnetic resonance imaging (MRI), also known as nuclear magnetic resonance imaging, is a technique for creating detailed images of the human body.
The technique uses a very powerful magnet to align the nuclei of atoms inside the body, and a variable magnetic field that causes the atoms to resonate, a phenomenon called nuclear magnetic resonance. The nuclei produce their own rotating magnetic fields that a scanner detects and uses to create an image.
An MRI scan can be used as an extremely accurate method of disease detection throughout the body. They may be done to provide more information about a problem seen on an X-ray, ultrasound, or CT scan.
Computerized tomography or CT scan as it is called combines data from various X Rays to provide a detailed image of the body structures. It produces as 2-dimensional slice image or section of the body. The data can be converted into a 3-dimensional image as well. CT Scan images are helpful in assisting doctor to diagnose certain conditions.
Ultrasound is performed for a number of situations. It is one of the most popular medical imaging techniques in practice for many years. It uses high-frequency sound waves and echoes for imaging. There are different types of ultrasound among them the 3D ultrasound imaging, and Doppler Ultrasound is widely used. 3D imaging allows early detection of cancerous and benign tumors, it visualises the fetus and assess its development and visualises blood flow in various organs. Doppler ultrasound measures the frequency change of the echoes and calculates the speed of the object. It is used to measure the heart, arteries and blood flow.
X-Ray examination creates images of bones to help in diagnosing injuries or conditions. The body passes through ionising radiation in small amount produced by the X-Ray machine that is made to fall on the film to produce an image. The radiation administered depends on which area needs to be filmed. When compared to a large area like spine, a small area like hand will receive lesser dosage. Radiographer or a radiologist is the health practitioners who conduct X-Ray examinations and prepares the findings report.
During the X-Ray, a small amount of ionising radiation is passed through the body. Earlier it went to a sheet made of special film, but now the examination uses a device to capture the X-Ray transmitted to create an electronic image. The bones block the radiation and displays as white or grey in the image. The radiation passes through air spaces. The lungs appear black.
Equipped with cutting-edge technologies and is an integral part of patient care. The department of Lab services has a team of skilled doctors, who bring a rich experience with them to handle even rare and complex cases.
The laboratory services range from routine blood tests – such as total cholesterol, Pap test and white blood cell count – to complex, gene-based, line probe assay and microbial identifications. The lab unit performs medical tests that aid in the diagnosis or detection of diseases, measure the progress or recovery from a disease or confirm that an individual is free from disease.
