What is a CT Pulmonary Angiography Scan?
Specifically, a CT Pulmonary Angiography (CTPA) examines the blood vessels inside your lungs in high detail. First, our technicians inject a safe, iodine-based contrast dye into an arm vein. Consequently, our advanced scanners capture rapid cross-sectional pictures as the contrast flows through your pulmonary arteries.
Therefore, doctors consider it the primary diagnostic test for detecting pulmonary embolisms (blood clots in the lungs) and vascular abnormalities. For more detailed clinical information, you can read the RadiologyInfo guide on pulmonary embolism imaging. Similarly, if you only need lung parenchyma evaluation without vascular contrast, you might prefer an HRCT chest scan instead.
Before Your CT Pulmonary Angiography Scan, Please Bring:
In order to ensure a smooth appointment, please review the required documents and preparation steps listed below.
- Doctor’s prescription: Valid referral from a registered medical practitioner.
- Previous reports: Past chest X-ray, CT, or D-dimer blood reports for clinical comparison.
- Blood test reports: Recent Serum Creatinine/eGFR report (done within 30 days) since contrast is required. You can book this routine blood test with us or learn more from the Mayo Clinic guidelines.
- Medications & History: List of current medications and relevant medical history (allergies, breathing difficulties, kidney disease).
- Insurance documents: If applicable, bring your insurance ID card and photo ID for cashless processing.
Is Contrast CT Pulmonary Angiography Scan Safe?
Meanwhile, this examination requires an intravenous contrast agent to visualize the pulmonary blood vessels clearly. Before contrast administration, our team reviews relevant medical history and kidney function information when clinically appropriate. Patients should inform the imaging team about previous contrast reactions, kidney disease, pregnancy, or other relevant medical conditions.
CT Pulmonary Angiography Scan Radiation Safety & Quality Standards
Furthermore, CT imaging involves ionizing radiation. Our facility follows applicable radiation safety requirements and established protocols designed to minimize unnecessary radiation exposure while maintaining diagnostic image quality.
Consequently, we maintain rigorous NABH, NABL, and AERB compliance standards to guarantee maximum safety for every patient visiting our center.
