High-Precision 640-Slice CT Scan at Islamabad Diagnostic Centre

Modern imaging techniques include CT scans (Computed Tomography), which are rapid and painless diagnostic tests. A CT scan utilizes an X-ray machine that rotates to capture cross-sectional images, also known as slices, of various body parts. This process provides detailed images of bones, lungs, blood vessels, and organs. At Islamabad Diagnostic Centre, we are proud to introduce our 640-slice CT scan, which offers enhanced precision and accuracy in imaging.

Latest CT Technology

What is a 640 Slice CT scan?

The 640-slice CT scan represents the latest technology in medical imaging. It is a highly precise and ultra-fast CT scanner that captures images in a single rotation. Unlike conventional CT scanners, this advanced model boasts ultra-fast speed, enhanced accuracy and precision, and significantly reduced scanning time. It is also a safer option for patients due to its low radiation exposure. As a result, the scan produces high-resolution 3D images of the body, leading to more accurate and reliable diagnoses.

Technology Comparison

How is it different from conventional CT scanners?

The following features of a 640 Slice CT scan make it different from a conventional CT scanner:

1

Output per Cycle of 640 Slice CT scan

When examining larger organs such as the heart, kidneys, and lungs, a conventional CT scanner (16, 64, or 68 slices) requires multiple cycles and rotations to capture images from different angles.

640-slice CT Scanner needs only a single rotation to cover the entire organs

2

Fast Speed and movement artifacts

A beating heart is difficult to capture with conventional CT Scanners as it blurs the image, and it can only capture an image if the heart rate is controlled. Whereas a 640 Slice CT scan captures the full cycle in one heartbeat while keeping the motion static and frozen.

3

Lower Radiation Exposure

Patients choose the latest 640-slice CT scanner due to its significant advantage of low radiation exposure during the main analysis.

4

Major Clinical Uses

16-slice and 128-slice CT scanners are suitable for routine body imaging in trauma cases and simple scans. In contrast, 640-slice scanners are used for analyzing complex and critical clinical cases, such as assessing children’s heart conditions, examining the coronary arteries, or evaluating blood flow through organs to check for any obstructions.

Clinical Applications

Common Conditions it Helps Diagnose

A 640-slice CT Scanner is best used to diagnose some complex conditions like:

Coronary artery disease (CT Coronary Angiography)
Congenital heart diseases (especially in pediatric and adult congenital cases)
Cardiac functional assessment (ventricular function, myocardial perfusion)
Aortic diseases (aneurysm, dissection)
Pulmonary embolism (CT Pulmonary Angiography)
Acute stroke (CT perfusion and CT angiography)
Cerebral aneurysms and arteriovenous malformations (AVMs)
Complex vascular disorders (carotid, renal, mesenteric, and peripheral arterial disease)
Trauma (whole-body CT) for rapid assessment of multiple injuries
Oncologic imaging requiring dynamic perfusion or multiphase studies (e.g., liver, pancreas, kidneys)
CT Coronary Angiography

How to Do CT Coronary Angiography Using 640 Slice CT?

CT Coronary angiography is an image analysis of coronary arteries using 640 Slice CT scan.

To perform CT Coronary angiography using 640-slice CT includes following requirements:

1 Patient preparation

Before the Scan

  • Do not drive alone
  • For females: rule out pregnancy or breastfeeding
  • Fasting 2 hours before procedure
  • Shave chest region for ECG
  • Take cardiac medications as usual
  • Do not use mobile before procedure

Avoid Before Procedure

  • No tea/coffee/caffeine/chocolates for 12 hours
  • No exercise on the day
  • Smokers: do not smoke on the day of procedure
  • History of asthma - check contraindications for nitrates & ß-blockers

Bring Medical Records

  • Previous ECG and Echocardiography (Echo) reports
  • If PCI (angioplasty/stenting) done: bring CD and report
  • If CABG surgery done: bring surgical notes/operative report and related medical records

Procedure Information

  • Practice breath holding at home (12-15 seconds)
  • Total procedure time: 3-4 hours (including preparation)
  • Actual CT scanning: approximately 20 minutes

2Imaging procedure Protocol

1Asthma: Do NOT give beta blockers (consider Ivabradine after cardiology consult)
2HR < 60 bpm - constantly monitor through pulse oximeter
3BP < 130/90 mmHg
4Anxiety control: 5-6 Rivotril drops
5IV line: 18G cannula, preferably in right antecubital vein
6History of allergy: pre-medicate with Prednisolone & Diphenhydramine
7Perform baseline ECG - look for abnormality/PVCs/Tall T waves
8EF (Ejection Fraction) must be > 35%
9Front open gown

3. Post Imaging Analysis

After acquisition of the CT Coronary Angiography, post-processing is performed on advanced workstations such as Vitrea, and Advantage Workstation (AW). Coronary arteries are analyzed using Multi-Planar Reformations (MPR), Curved Planar Reformations (CPR), Maximum Intensity Projections (MIP), and Volume Rendering Technique (VRT) to accurately assess and grade the severity of coronary artery stenosis, evaluate plaque morphology, quantify coronary calcium, and generate comprehensive diagnostic reports.

FAQs

Frequently Asked Questions

1. What is the purpose of using 640 Slice CT Scan Technology?

The purpose of a 640-slice CT scanner is to deliver fast, precise, and low-dose diagnostic imaging, particularly for complex cardiac, neurological, vascular, and oncologic conditions.

2. How many images a single 640 Slice CT Scan Technology can take?

A 640-slice CT scanner can capture up to 640 images (slices) in a single rotation, and a full CT examination may produce several thousand reconstructed images for diagnostic interpretation.

3. Why 640 Slice CT scan is best for the heart?

640 Slice CT scan can capture the entire heart in a single rotation in about 5 secs.

A 640-slice CT scanner is best for heart imaging because it can image the entire heart in a single heartbeat, producing highly detailed, accurate images with fewer motion artifacts, lower radiation exposure, and faster scan times. This makes it especially valuable for diagnosing coronary artery disease and other complex cardiac conditions.
