Cardiovascular (CTA 64 SLICES)


Introduction
The fast growth of science and technology is very assist us in everyday activities, this also in the field of health especially of radiology. Since founded of CT scan by Sir Godfrey Hounsfield and of Allan Cormack in 1969, now CT scan have ability for multi CT slice in once rotation in same time.

CARDIOVASCULAR CTA WITH CTA 64 SLICES
Unlike other body parts, imaging of the heart poses a few special challenges. This is because involuntary motion of heart and the heart is small anatomic structures. Because that for imaging the heart need a special tool a special technique. Basic requirement for cardiovascular CT
1. High temporal resolution (fast gantry rotation)-minimize motion artifacts.
2. High spatial resolution (depiction of small and complex cardiac anatomy
3. Fast continuous coverage (scan the whole heart or vascular system in a single breath hold scan)
4. Synchronization to heart beat-ECG gating for phrase consistent, volume imaging

So, Today’s technological benchmarks CT are called CT Scan 64 Slices. This machines have 0.33-0.37 s gantry rotation, 83 ms min temporal resolution with dual source scanner, 64 x o,g mm heart scan in 5-7 64 x 0,6 mm heart scan in 5 -7 s with Integrated Cardiovascular Evaluation

ADVANTAGE
1. Non invasive
2. Intra extra luminal info
3. Surrounding tissue info
4. Myocardial info
5. Fast exam and fast assessment
