[ SYSTEM_CODE: IMG-CARD-CTA ]

Non-Invasive CT Coronary Angiography

IMG-CARD-CTA

High-resolution 3D coronary architecture scanning.

A state-of-the-art procedure using high-speed computed tomography and intravenous contrast to visualize the absolute lumen of coronary arteries, checking for subclinical blockages, calcium build-ups, and ischemic heart disease risks.

Patient Preparation:

Fast for at least 4 hours before the scan. Strictly avoid caffeinated beverages (coffee, tea, energy drinks, soda) and tobacco on the day of the exam. Take all standard prescribed medicines with small sips of water.

Procedure Protocol:

An IV cannula is placed in a vein. You will lie on the motorized CT scanner table. Following breath-holding commands, the scanner takes full pictures of the heart in just 5 to 8 seconds. The complete session takes about 15 to 20 minutes.

Critical Clinical Safety Warnings:

Uses iodine-based contrast and low-dose radiation (5-8 mSv). Inform staff if you are pregnant, have severe asthma, diabetes, kidney dysfunction, or thyroid issues. Heart rate must be stable (a beta-blocker may be administered if heart rate >= 90 BPM).

Technical Diagnosis FAQs:
[ Q ] Is this a viable alternative to Catheter Angiography?
CT Angiography is patient-friendly and far less invasive than catheter insertion. With a negative predictive value of 99% to 100%, a normal scan guarantees you are virtually free of flow-limiting blocks without the invasive hospital recovery time.
[ Q ] What is the clinical sensitivity?
The advanced multi-detector CT provides excellent sensitivity of 95% and specificity of 98% in detecting coronary artery stenosis exceeding 50%.
[ SYSTEM_CODE: IMG-CARD-CAC ]

Coronary Artery Calcium (CAC) Scoring

IMG-CARD-CAC

Painless detection of calcified coronary arterial plaque.

A rapid, non-contrast CT scan that measures the location and quantity of calcified plaque deposits inside the walls of the coronary arteries. The findings are expressed as an Agatston Calcium Score, serving as a powerful predictor of future cardiac events.

Patient Preparation:

No fasting is necessary. Avoid all forms of caffeine, carbonated drinks, and smoking for at least 4 hours prior to the scan to ensure a stable, low resting heart rate.

Procedure Protocol:

Electrodes are attached to your chest to sync scanning with your heart rhythm. You lie still on the CT scan table as it passes through the scanner. You will hold your breath for 10 seconds. The scanning is completed rapidly with zero discomfort.

Critical Clinical Safety Warnings:

Uses low-dose ionizing radiation. Inform our radiographer if you are pregnant or have had previous coronary stents (stents block calcification scoring and render this test redundant).

Technical Diagnosis FAQs:
[ Q ] What does a high Calcium Score indicate?
A positive score indicates the physical presence of atherosclerotic plaque. Higher scores correlate with a higher risk of coronary narrowing or heart attack, indicating the need for aggressive preventative therapy.
[ SYSTEM_CODE: IMG-CARD-MRA ]

Magnetic Resonance Angiography (MRA)

IMG-CARD-MRA

Radiation-free vascular mapping of major arteries.

A non-invasive medical imaging scan that utilizes a powerful magnetic field and radiofrequency waves to compile detailed, cross-sectional images of the major blood vessels inside the body without exposing you to ionizing radiation.

Patient Preparation:

Wear loose, comfortable clothing. Remove all jewelry, metallic accessories, zippers, dentures, watches, and credit cards before entering the magnetic scanner zone. Fasting is only required if contrast is prescribed.

Procedure Protocol:

You lie on a sliding examination table. Straps and cushions help you stay completely still. Earplugs are provided to block the harmless thumping noises. The table slowly moves through the scanner, which takes about 30 to 45 minutes.

Critical Clinical Safety Warnings:

Strictly prohibited for patients with implanted pacemakers, defibrillators, cochlear implants, brain aneurysm clips, or metallic coils. Contrast injections contain gadolinium and are iodine-free (less allergic risk).

Technical Diagnosis FAQs:
[ Q ] Does the contrast injection contain iodine?
No, MRA contrast uses gadolinium, which is much safer, less likely to trigger allergies, and contains zero iodine. You may feel a brief flushing sensation or metallic taste during injection.
[ SYSTEM_CODE: IMG-CARD-CIMT ]

Carotid Intima-Media Thickness (CIMT) Ultrasound

IMG-CARD-CIMT

Early detection of subclinical vascular stroke risks.

An advanced ultrasound technique measuring the combined thickness of the intima and media layers of the carotid artery wall. Used to identify subclinical atherosclerosis and evaluate overall risk for heart attacks and strokes.

Patient Preparation:

No special preparation or fasting is required. Wear a loose collar that allows easy access to the sides of your neck.

Procedure Protocol:

You will lie flat on an examination table. A specialized technician applies a clear, warm gel to the sides of your neck. The ultrasound transducer probe is gently guided back and forth. The test takes approximately 15 minutes.

Critical Clinical Safety Warnings:

100% safe, non-invasive, radiation-free, and pain-free.

Technical Diagnosis FAQs:
[ Q ] Who is candidate for a CIMT Test?
Recommended for patients at intermediate risk (6%-20% 10-year CVD risk), individuals with a family history of premature heart disease, post-menopausal women, and men over 35 with underlying risk factors like hypertension, obesity, smoking, or diabetes.
[ SYSTEM_CODE: IMG-CARD-ECHO ]

Echocardiography (Heart Ultrasound)

IMG-CARD-ECHO

Real-time structural and hemodynamic heart analysis.

A painless ultrasound scan of the heart that provides real-time visualization of heart chamber sizes, muscle wall thickness, valvular flow structures, and overall cardiac pumping function.

Patient Preparation:

No special preparation or fasting is required. Wear comfortable two-piece clothing, as you will be asked to remove your upper garments and wear a clinical examination gown.

Procedure Protocol:

Three ECG electrodes are attached to your body to track heart cycles. A transducer probe with color-free acoustic gel is guided across your chest in different positions. The exam is completely painless and takes 10 to 15 minutes.

Critical Clinical Safety Warnings:

100% safe, non-invasive, and radiation-free.

Technical Diagnosis FAQs:
[ Q ] What detailed metrics are acquired?
Echocardiography measures chamber volumes, myocardial pumping efficiency (ejection fraction), valvular stenosis/regurgitation, pulmonary pressures, and screens for abnormalities like congenital holes or abnormal growths.
[ SYSTEM_CODE: IMG-CARD-DOPP ]

Peripheral Vascular Doppler Ultrasound

IMG-CARD-DOPP

Non-invasive mapping of circulatory blood flow.

An ultrasound scan utilizing high-frequency sound waves that bounce off circulating red blood cells to map and calculate blood flow speeds and check for blocks or blood clots in major arm or leg arteries.

Patient Preparation:

No special preparation or fasting is required. Keep comfortable clothing that can be rolled up to expose limbs.

Procedure Protocol:

Specialized gel is applied to the arm or leg. The technician guides the probe while blood pressure cuffs may be inflated to measure pressure indexes. The scan takes 15 to 20 minutes.

Critical Clinical Safety Warnings:

100% safe, non-invasive, radiation-free, and pain-free.

Technical Diagnosis FAQs:
[ Q ] How does Doppler differ from standard ultrasound?
Standard ultrasound creates structural organ images, whereas Doppler translates sound frequency changes into blood-flow directions and velocities, highlighting vascular narrowings and deep vein thrombosis (DVT).
[ SYSTEM_CODE: IMG-CARD-EST ]

Treadmill Exercise Stress Test

IMG-CARD-EST

Hemodynamic heart monitoring under physical load.

A well-established cardiovascular investigation that monitors heart rate, blood pressure, and ECG patterns under progressive treadmill exercise to evaluate for latent myocardial ischemia.

Patient Preparation:

Bring athletic running shoes and loose sports apparel. Eat only a light snack and strictly avoid caffeine, alcohol, and heavy fats for at least 4 hours before the test. Inform our medical team of any active medications.

Procedure Protocol:

Electrodes are secured to your chest and connected to a live ECG monitor. You will walk on a treadmill that gradually increases in speed and incline (Bruce Protocol). The test continues until you reach your target heart rate, taking about 30 minutes in total.

Critical Clinical Safety Warnings:

Excludes patients with physical disabilities, severe arthritis, unstable coronary syndromes, uncontrolled hypertension, severe aortic valve stenosis, life-threatening arrhythmias, or recent aortic operations.

Technical Diagnosis FAQs:
[ Q ] What happens if the stress test is positive?
A positive test suggests significant coronary artery obstruction (over 70% blockage). Your cardiologist will evaluate the severity and may recommend a highly precise CT Coronary Angiogram or catheterization.
[ Q ] Can a negative test completely rule out heart disease?
No. The treadmill stress test has a clinical sensitivity of 70% to 80%. It primarily detects severe blockages and might not catch early-stage, mild-to-moderate plaque that has not yet restricted flow.
