Angioscanner CT avancé à Dubaï

The total appointment time is approximately 20-45 minutes, which includes check-in, IV placement, safety screening, and the scan itself. The actual CT scanning portion takes only 10-20 seconds to a few minutes depending on the body region being imaged. Most of the appointment time is dedicated to preparation and ensuring contrast is administered safely. Cardiac-gated coronary CTA may take slightly longer to optimise heart rate before scanning.

CT angiography is considered very safe when performed with appropriate protocols. At DCDC, we use low-dose CT techniques that significantly reduce radiation exposure compared to older scanners. We screen kidney function before every contrast-enhanced scan to minimise the risk of contrast-induced nephropathy. For patients with mild iodine allergies, premedication with steroids and antihistamines can allow safe scanning. The diagnostic benefit of accurate vascular imaging typically far outweighs the small risks involved.

CT angiography is non-invasive, with contrast delivered through a simple IV in your arm, while catheter angiography requires inserting a thin tube through an artery in your groin or wrist. CTA is the preferred first-line diagnostic tool because it is faster, safer, and avoids the hospitalisation and recovery time associated with catheter procedures. Catheter angiography is typically reserved for cases where intervention (stenting or balloon angioplasty) is planned during the same procedure, or when CTA findings require further clarification.

Yes, fasting for 4-6 hours before the scan is required to reduce the risk of nausea from contrast injection and to ensure optimal image quality. You may drink clear water during the fasting period to stay hydrated, which actually helps with IV access and contrast clearance. If you take regular medications, continue taking them with a small sip of water unless specifically instructed otherwise by your doctor. Our booking team will provide detailed preparation instructions when you schedule.

When the iodinated contrast is injected through your IV, you will typically feel a warm flush spreading through your body, often starting in the chest and moving to the abdomen and limbs. Some patients notice a brief metallic taste in the mouth or a warm sensation in the pelvic area that may feel like you have passed urine (you have not). These sensations are completely normal, expected, and last only 15-30 seconds before subsiding entirely. The contrast is colourless and odourless.

We check kidney function (creatinine and eGFR) before every contrast-enhanced scan. Patients with mild kidney impairment can often proceed with contrast using hydration protocols before and after the scan. For moderate to severe kidney disease, your doctor and radiologist will weigh the diagnostic benefit against the risk of contrast-induced nephropathy. In some cases, alternative imaging such as MR angiography or non-contrast techniques may be recommended. We always take a personalised approach to contrast safety.

Standard reports with 3D reconstructions are ready within 18-24 hours. For urgent cases such as suspected pulmonary embolism, acute aortic syndrome, or stroke, we provide same-day results and can communicate critical findings directly to your referring physician immediately. Your report includes detailed findings, measurements, and 3D images that can be shared digitally with your healthcare team for treatment planning.

For insurance coverage, most plans require a physician referral specifying the clinical indication and body region for the CTA. Referrals from cardiologists, vascular surgeons, neurologists, pulmonologists, or general practitioners are accepted. If you do not have a referral, our in-house physicians can evaluate your symptoms and provide one. Self-pay patients may book directly. We accept direct billing with over 20 insurers and handle pre-authorization on your behalf.
