Benefits of Cardiac CT
CT Coronary Angiography has emerged as the most reliable non-invasive modality for evaluation of heart diseases.
- Takes only a few seconds to evaluate heart condition
- Non-invasive and painless
- No hospital admission required, it is an OPD basis procedure
- It is a safe and convenient procedure. Cardiac CT imaging process for the patient is almost similar to any other contrast CT scanning
Use of Cardiac CT
For Preventive Cardiac Screening:
- CT angiography is highly useful for patients who are asymptomatic but at high risk of having coronary artery disease.
- Patients presented with atypical chest pain or breathlessness, patients giving history of chronic smoking, chronic hypertension, strong family history of premature heart disease and those with unclear electrocardiographic changes or stress-test results.
- It is also a screening tool for patients on Cholesterol reducing medications and for patients on exercise and nutrition therapies. The CT coronary angiogram screening will help them to estimate the progress / regress of the disease.
For Post-Operative Screening and Evaluation:
CT angiography is also recommended for patients with history of open heart surgery and had bypass grafting (Coronary Artery Bypass Grafting).It is a convenient way to follow up and evaluate graft functioning and detect any blockages to the bypass grafts inserted into the coronary arteries. Patients who had undergone CABG, CT Angiography can clearly demonstrate grafts blockages if any, the extent of graft functioning, the points of grafts insertions (Ostiums& anastomotic junctions) in three dimensional views.
For Post-Stenting Screening and Evaluation:
With recent advancements in stent technology, insertion of stents into coronary arteries is becoming a preferable methods than the open heart surgeries in CT Angio (CTA) reveals the number of obstructions and the extent of these obstructions in the blood vessels without any invasion. This helps in planning and preparation for the treatment. For example, if stenting is required, you will have beforehand knowledge of the type and number of stents required. CTA helps in better planning of treatment both in terms of time and money. It can save any last minute surprises when compared to direct admission to a Cath lab.
CT Angiography Vs Cath lab Angiography
Coronary Angio in a cath lab is an invasive procedure to obtain images of blocked arteries in your heart and then decide and do corrective actions like ballooning and stenting. While for corrective actions it is highly recommended procedure, for screening of heart and determing the state of the heart, Physicians opt for CT Angio. Below is the table of comparison between the
|Coronary Angiography (Cath lab)
||CT Coronary Angiography
|Invasive procedure -
a catheter is inserted
through a large artery of
the body till the tip of one
of the Coronary artery
||Non-invasive procedure -
only an injection of
contrast dye via a needle
in peripheral vein is given
|Requires day care admission (4-10 hours)
||Outpatient visit (1-2 hours)
|Risk of local arterial
perforation or stroke
||Safer (no risk of local
damage or stroke)
|Cannot visualise soft
plaque - which is most
likely to rupture and
cause a heart attack
||Unique ability to visualise
soft plaque and calcium
|Normal activities can only
be resumed after 48 hours
||Normal activities can be
resumed right after
What's so special about Cardiac CT at Vrinda
The Ingenuity 128 Slice CT at Vrinda, is the most advanced CT scanner in the world. Moreover it is also equipped with award winning iDose4 technology for controlling X-ray radiation to patients.
Lowest XRay exposure
State of the art 128 Slice Ingenuity CT with a very unique technology called iDose4.
iDose4 ensures that the patient is exposed to lowest possible X-rays while the best quality of image is generated.
Philips unique Adaptive multi cycle reconstruction algorithm achieves temporal resolutions as fast as 53 milliseconds which leads to excellent quality images demonstrating even tiny plaques and calcifications.
Cardiac Imaging for High BMI patients
Doing cardiac screening of heavy patients (high BMI) has always been a challenge. But with the latest technology of Ingenuity CT at Vrinda, excellent images can be produced for even heavy patients.
Cardiac imaging for patients with Arrhythmia
If irregular beats occur, they can adversely affect the image quality of the scan .With Philips new Auto arrhythmia editing tool, irregular beats can be automatically detected, edited and the raw data reconstructed again to generate images without any artifacts.
Philips Auto arrhythmia editing is used to automatically detect irregular ECG events during a cardiac CT.
