One of the most advanced CT scanners available in Pakistan — capturing an entire organ in a single rotation, imaging the heart in one heartbeat, and delivering razor-sharp results at ultra-low radiation dose.
Al-Nasar Lab now offers a 640-slice CT scan in Lahore — a wide-detector, volumetric scanner that images whole organs in one rotation and the entire heart in a single heartbeat, with advanced dose-reduction technology. It is a major step up from conventional CT for cardiac, stroke, pediatric, trauma and whole-organ imaging.
How a 640-slice CT scanner is better
Twelve real advantages of wide-detector, volumetric CT:
Whole-Organ Coverage
Up to 16 cm detector captures an entire organ — brain, heart, lungs or liver — in a single rotation with no table movement, reducing artifacts and improving accuracy.
One-Heartbeat Cardiac CT
Images the whole heart in a single heartbeat: coronary CT angiography, calcium scoring, congenital heart disease and bypass-graft evaluation — far less dependent on heart rate.
Ultra-Low Radiation Dose
Advanced iterative reconstruction delivers excellent images at a greatly reduced dose — ideal for children, young adults, follow-ups and cardiac CT.
Motion-Free Imaging
Extremely fast acquisition minimises motion artifacts — ideal for elderly, breathless, trauma and emergency patients.
Dynamic 4D Imaging
Evaluates physiology, not just anatomy: brain perfusion in stroke, tumour perfusion, lung ventilation, organ blood flow and dynamic joint studies.
Advanced Stroke Imaging
Non-contrast CT, CT angiography and CT perfusion in one sitting for rapid stroke treatment decisions.
Pediatric Excellence
Fast scanning and low radiation often avoid the need for sedation thanks to the very short scan time.
Emergency & Trauma
Rapid whole-body trauma imaging with excellent quality even in critically ill patients.
Superior Neuro Imaging
Whole-brain perfusion without table movement; evaluation of stroke, aneurysms, AVMs and cerebral blood flow.
High Spatial Resolution
Crisp detail of coronary arteries, temporal bones, the inner ear, small lung nodules and fine fractures.
Comfortable Experience
Short scan time and less breath-holding — suitable for patients who cannot cooperate well.
Advanced Post-Processing
3D reconstructions, virtual endoscopy, cardiac functional analysis, CT-derived FFR, vessel analysis and perfusion analysis.
640-slice CT vs conventional CT
| Feature | 640-Slice CT | Conventional CT |
|---|---|---|
| Detector coverage | Up to 16 cm — whole organ in 1 rotation | Narrow — multiple rotations, table moves |
| Cardiac CT | Whole heart in a single heartbeat | Multiple beats, heart-rate dependent |
| Radiation dose | Ultra-low (iterative reconstruction) | Higher |
| 4D dynamic / perfusion imaging | Yes — perfusion & blood flow | Limited or not available |
| Motion artifacts | Minimal (ultra-fast acquisition) | More likely |
| Stroke workup | Non-contrast + CTA + perfusion in one | Often separate scans |

Frequently Asked Questions
What is a 640-slice CT scan?
A 640-slice CT is a wide-detector, volumetric scanner (up to 16 cm coverage) that can image an entire organ in one rotation and the whole heart in a single heartbeat — with higher speed, higher resolution and lower radiation than conventional CT.
Is the 640-slice CT scan safe / low radiation?
Yes. Advanced iterative reconstruction produces excellent image quality at a significantly reduced radiation dose — especially valuable for children, young adults and follow-up studies.
Can it do a cardiac CT in one heartbeat?
For many patients, yes — the whole heart can be imaged in a single heartbeat, making coronary CT angiography and calcium scoring faster and less dependent on heart rate.
Is it suitable for children?
Yes. The very short scan time and low dose make it excellent for pediatric imaging and often avoid the need for sedation.
