MRI

MRI is a non-invasive technique to diagnose diseases of several organ systems. It uses radio waves and magnetic fields to provide detailed images. The contrast agent may or may not or be used during an MRI.

Our offerings

  • MR Contrast Studies: MR contrast studies are specialized MRI procedures that involve injecting the contrast dye and combining radio and magnetic waves. The dye allows doctors to visualize organs, blood vessels, and soft tissue with improved clarity. Doctors recommend MR contrast studies to evaluate inflammation, tumors, and blood supply in certain organs.
  • MR Angio/Venography: MR angiography is the procedure to determine blood flow in the target organs. The contrast agent used in MR angiography makes the blood vessels opaque, thus visualizing the blood vessels. It is used for the diagnosis of blood clots or atherosclerosis. MR venography is the technique that assists in visualizing the veins. It helps in diagnosing stroke, blood clots, and other venous diseases.
  • MR Spectroscopy: It is used to detect biochemical alterations in the brain, particularly the presence of tumors. The standard MRI detects the presence of tumor location. However, MR spectroscopy compares normal brain tissues with abnormal brain tissues. The technique also detects the alteration in tissue biochemistry during epilepsy and stroke.
  • MR Perfusion: MR perfusion imaging is a technique to measure cerebral perfusion by assessing several components, such as cerebral blood flow, mean transit time, and cerebral blood volume. The technique helps in evaluating neurodegenerative conditions like Alzheimer's disease.
  • Cardiac MRI: Cardiac MRI is a tool to determine the overall health status of the heart. It evaluates the beating pattern, function, and structure of the heart. It also detects coronary artery disease, heart muscle damage due to heart attack, and structural cardiac disorders, such as heart valve diseases and other heart defects.
  • Functional MRI: This technique allows the surgeon to determine the changes in blood flow in a particular part of the brain during brain activity. It assists in detecting brain abnormalities that are undetected by other imaging techniques.
