CT PULMONARY ANGIO

CT Pulmonary Angiography (CTPA) is an advanced diagnostic imaging test used to evaluate the pulmonary arteries, which carry blood from the heart to the lungs. The examination uses contrast-enhanced CT technology to create detailed images of the blood vessels within the lungs and helps diagnose life-threatening conditions such as pulmonary embolism (blood clots in the lungs).

CT Pulmonary Angiography is considered the gold standard imaging test for detecting pulmonary embolism. It also helps identify pulmonary artery abnormalities, vascular malformations, lung diseases, and causes of unexplained chest pain or shortness of breath.

The procedure is fast, highly accurate, and provides detailed visualization of both the pulmonary circulation and surrounding lung structures.

Benefits of the Test

• Accurately detects pulmonary embolism.
• Provides detailed visualization of pulmonary arteries.
• Helps evaluate unexplained chest pain and breathlessness.
• Identifies vascular abnormalities in the lungs.
• Assists in emergency diagnosis and treatment planning.
• Fast and highly reliable imaging procedure.
• Provides comprehensive assessment of pulmonary circulation.
• Supports early detection of potentially life-threatening conditions.

Why Doctors Recommend This Test

Doctors may recommend CT Pulmonary Angiography for patients experiencing sudden shortness of breath, chest pain, suspected pulmonary embolism, coughing up blood, unexplained low oxygen levels, pulmonary hypertension, or abnormal findings on chest imaging studies.

The examination helps identify blood clots, narrowing of pulmonary arteries, vascular abnormalities, and other conditions affecting blood flow between the heart and lungs.

Preparation Before Test

• Fasting may be required for 4–6 hours before the examination.
• Drink adequate water unless instructed otherwise.
• Inform the doctor about allergies to contrast dye.
• Inform the radiology team about kidney disease or diabetes.
• Notify your doctor if you are pregnant or breastfeeding.
• Bring previous imaging reports if available.

Normal Reporting Time

Most CT Pulmonary Angio reports at Focus Diagnostics are available within 2–3 hours after completion of the scan. Critical findings are immediately communicated to the referring physician.

Who Should Take This Test?

This test may be recommended for:

• Individuals with suspected pulmonary embolism.
• Patients with sudden chest pain.
• People experiencing unexplained shortness of breath.
• Individuals with pulmonary hypertension.
• Patients with abnormal chest imaging findings.
• People with unexplained low oxygen levels.
• Individuals at risk of blood clots.
• Patients requiring pulmonary vascular assessment.

Detailed Information

CT Pulmonary Angiography uses intravenous contrast material and advanced CT imaging technology to visualize the pulmonary arteries in great detail. During the scan, contrast dye is injected into a vein, allowing radiologists to assess blood flow through the lungs and identify any blockages or abnormalities.

The test is especially important for diagnosing pulmonary embolism, a potentially life-threatening condition caused by blood clots obstructing pulmonary blood vessels. Early detection allows prompt treatment and reduces the risk of serious complications.

CTPA may also help diagnose pulmonary artery aneurysms, vascular malformations, pulmonary hypertension, and other cardiopulmonary disorders.

At Focus Diagnostics, CT Pulmonary Angiography is performed using advanced CT scanners and interpreted by experienced radiologists to ensure accurate diagnosis and rapid reporting.
