CT-SCAN

Now, get a comprehensive evaluation of the health of your heart in just a few minutes! Simply walk in for a Coronary CT Angiography on our Cardiac CT Scanner to identify any blockage in the arteries that supply blood to your heart.

The test is safe and is not an invasive procedure unlike conventional catheter angiography. A normal report rules out possibility of a coronary artery blockage in the near future.

Coronary CT Angio is also extremely useful in evaluating patency of stents and the condition of the bypass graft post-CABG.

A preliminary screening of the arteries can also be done just by evaluating the Calcium Score. A low Calcium Score is synonymous with low clinically significant soft plaques in the coronary arteries. The Calcium Scoring test can be completed in a matter of seconds.

To know the condition of your heart call us today and register for a Coronary CT Angio or Calcium Scoring test for yourself and your loved ones. Remember, often in heart attack cases, the only symptom of the disease is the attack itself.

What is the need for cardiac CT?

Coronary Artery disease (CAD) is the leading cause of death in the industrialized world.

  • “Screening” is a widely accepted strategy to combat CAD for early detection of stenosis of the coronary artery lumen.
  • Exclusion of stenosis in non- symptomatic high risk patients.
  • Prior to major (non-cardiac) Surgery.
  • Atypical (unstable) chest pain.
  • Refractory chest pain with doubtful coronary origin.
  • Non-conclusive stress tests.
How is the procedure performed?
  • Prior appointment taken (at any convenient time for the patient).
  •  To come 4 hours fasting for the examination (to take all medicines as per schedule) with all previous cardiac-related information.
  •  Stabilization of heart rate with an oral β-blocker (if required).
  •  If pulse rate low and regular, the patient is taken for the examination.
  • An IV line is put into a peripheral vein in the arm.
  •  Breathing rehearsal for approximately 20 second breath-hold.
  •  CT calcium scoring study is performed with a non contrast scan, in a single breath hold.
How is it performed?
  • During a CT scan, you lie on a table inside a doughnut-shaped machine called a gantry. An X-ray tube inside the machine rotates around your body and sends small doses of radiation through it at various angles. As X-rays pass through your body, different tissues absorb different amounts. Detectors inside the gantry measure the radiation leaving your body and convert the radiation into electrical signals. A computer gathers these signals and assigns them a color ranging from black to white depending on signal intensity. The computer then assembles the images and displays them on a computer monitor.
What are the dangers of CT scanning?
  • Though it involves x-ray radiation, there are no dangers in practice. Only in pregnant women, it should be done after weighing all the risks of exposing your     fetus to radiation and benefits (like any other CT investigation).
  •  Dangers of contrast medium
What is a ‘contrast’ medium?
  • A contrast is a iodinated compound injected intravenously (peripherally) to opacify the vessels and enhances the ability of CT scans to pick up abnormalities Only the very safest contrast (non-ionic) is used for all the patients in our centre. This gives better compliance with patients, as compared to ionic contrast, which is cheaper but gives more adverse reactions.

    Dangers of contrast medium

    Though not so common, the contrast medium involved in a CT scan poses a slight risk of allergic reaction.

    • Most reactions result in hives or itchiness.
    • For individuals with asthma who become allergic to the contrast medium, the reaction can be an asthma attack.
    • In very rare instances, an allergic reaction might cause swelling in your throat or other areas of your body.

    If you experience hives, itchiness or swelling in your throat during or after your CT exam, immediately tell your technologist or doctor. We keep an emergency kit for all commonly known adverse reactions.

Who is at ‘ high-risk’ for contrast injection?
  • Past history of reaction to contrast/any other drugs.
  • Bronchial asthma.
  • Cardiac/kidney disease /diabetes etc.

 

What can you expect during a CT scan?
  • Expect the exam to last no more than an hour, depending on the preparation needed and whether it includes the use of contrast medium. The scan itself may take just a few minutes.

    • During the CT scan you lie on a narrow table that slides through the opening of a large device called the gantry. The table can be raised, lowered or tilted.     Straps and pillows may help you stay in position. During a CT scan of the head, the table may be fitted with a special cradle that holds your head still.
    • As the X-ray tube rotates around your body, the table slowly moves through the gantry. While the table is moving you may need to hold your breath to avoid blurring the images. You may hear clicking and whirring noises. Each rotation yields several images of thin slices of your body.
    • During this time, a technologist in a shielded room supervises the CT scan and monitors the images as they appear on the computer screen. The technologist can see and hear you, and you can communicate via intercom.
    • If an infant or small child is having the CT scan, you may be allowed to stay with your child during the test. If so, you may be asked to wear a lead apron to shield you from X-ray exposure.

 

(A) POTENTIAL INDICATION DETECTION OF CORONARY ARTERIAL DISEASE – Symptomatic – Evaluation of Chest pain syndrome (use CT Angiogram)

Symptomatic – Acute Chest pain (use CT Angiogram)

  • Low pretest probability of CAD, No ECG changes and serial enzyme negative
  • High pretest probability of CAD, No ECG changes and serial enzyme negagive
  • “Triple ruleout” – exclude obstructive CAD, aortic dissection and pulmonary embolism.

Intermediate pretest probability of one of the above. ECG : No ST-segment elevation and initial enzyme negative

Asymptomatic without Chest pain syndrome (use CT Angiogram)

  • High risk cardiac heart disease

(B) CARDIAC MDCT – POTENTIAL INDICATION
