Dual-Source Computed Tomography

What are Dual-source computed tomography scans?

The dual-source CT scans are a type of computed tomography scan that uses two X-ray tubes arranged at 90 degrees to one another to produce cross-sectional images of any body part. It performs advanced coronary angiography, studies blood vessels, and guides surgeons to the correct targeted site. Dual-source CT scanners come in different generations, such as the 1st, 2nd, and 3rd generations, with many features for various medical conditions.

How does a Dual-source CT scanner operate?

Medical specialists may advise removing jewellery, wearing a hospital gown, and lying on the table prone, supine, or sideways based on the body part to be diagnosed. The dual-source CT scan comes with two X-ray tubes and two detectors positioned roughly at a 90-degree angle. These X-ray tubes and detectors provide temporal resolution independent of the patient’s heart rate, are positioned at the desired anatomical level, and rotate simultaneously to capture sharp images. The entire scan is typically completed within 20–30 seconds.

In a few cases, a contrast agent (contrast dye) is administered orally or rarely intravenously to highlight hard-to-reach places and produce clear images. The dual-source CT scan can be operated in two unique modes: single-energy mode, wherein the X-ray tubes operate at the same voltage, and dual-energy mode, where they operate at different energy settings.

Advantages of Dual Source CT Scanners (DSCT)

• Improved temporal resolution for ECG-synchronized cardiac scanning.
• It is superfast with flash technology per rotation.
• Covers large anatomical volumes.
• Fewer repeat scans with high accuracy.
• Offers ultrafast scanning.
• Quantify subtle changes. E.g., bone marrow defects.
• Higher chances of early detection with wide and micro coverage.
• Lowers radiation damage.
• Reduces side effects.
• Provides better comfort for patients of all sizes.

Clinical Indication for Dual Source CT Scanners (DSCT)

• Cardiac imaging for challenging heart cases.
• CT of the kidney, ureter, or bladder (CT KUB) for patients with uric acid stones.
• CT imaging for tumours for individuals with vascular tumours.
• Carriers of monosodium urate crystals may further lead to gout.
• Patients with reduced blood flow to the lungs and peripheral embolization.
