Medical Imaging and Surgery in Alwarpet, Chennai

The technology or the process of creating images of various parts of the human body for diagnosis and treatment purposes is known as medical imaging. The term, "medical imaging", includes various types of radiological imaging such as X-ray or radiographs, MRIs, CT scans, mammograms, etc.

What do you need to know about medical imaging?

All the non-invasive tests done in a department of radiology are known as medical imaging. This does not take place in a laboratory or require any sample collection. Medical imaging is very different from other lab methods. Some of the techniques used include: 

  • X-ray imaging or radiography
  • Ultrasonography or ultrasound imaging
  • MRI scan (magnetic resonance imaging)
  • PET scan (positron emission tomography)
  • Tactile imaging
  • Mammogram
  • Endoscopy
  • MEG (magnetoencephalography)
  • Fluoroscopy
  • EKG (electrocardiography)
  • Elastography
  • CT scan
  • Thermography
  • EEG (Electroencephalography)

What are the risk factors associated with imaging?

The risks associated with exposure to ionizing radiation include:

  • A person’s exposure to radiation is slightly increased. This may progress to cancer at a later age.
  • Tissue side effects, such as cataracts, skin redness, and hair loss, occur under relatively high radiation exposure, especially in CT scans.

How do you prepare for an imaging investigation?

You should prepare for an imaging exam by studying as much as possible about the procedures you will go through. Before the exam, the imaging center staff or radiologists may spend some time explaining exactly what will happen during the process. You can ask any questions that you have at that time. Inform them about any metal on or inside your body and if you have any allergies or phobia. 

Basically, your preparation will depend on the type of imaging exam. For example, you may need to fast or follow a special diet to prepare for such an exam 24 hours in advance or you may be required to eat and act normally.

What can you expect from medical imaging?

In almost all imaging examinations, you should try to follow these basic guidelines:

  • Calm down and relax
  • Try to be as still as you can
  • Follow the instructions of the radiology staff meticulously
  • Queries are welcome

What are the possible results of medical imaging?

Usually, the quality of the pictures you get depends in part on how well you follow the instructions and stay calm and relaxed. If you feel anxious or scared, please tell a technician or radiologist, they are there to help.

When do you need to see a doctor?

When you develop certain symptoms of a disease over a long period of time or a severe one for a short period, you must see a doctor. Your doctor will note down your medical history and perform a physical examination as the initial steps of diagnosis. You will then be recommended to undergo certain medical imaging and lab tests.

What is the importance of medical imaging?

Medical imaging is essential for doctors to make provisional diagnosis. It is used to make more accurate diagnoses and chalk out appropriate treatment plans.

What is a gamma scan?

Gamma scan is also known as scintigraphy. Scans are used to diagnose, stage and monitor diseases such as cancer. It captures 2-D images of radiation emitted by injected radioisotopes to help identify areas of biological activity that may be related to the disease. Also called a radionuclide scan.

What is a PET scan?

Positron emission tomography uses certain properties of isotopes and high-energy particles emitted by radioactive materials to diagnose or treat various pathologies. This scan reports the blood flow to various body parts, oxygen consumption or metabolism of organs and tissues. PET scans can identify problems at the cellular level, allowing your doctor to better understand complex systemic diseases such as cancer.
