Ten Years Progress in CCTA

Imaging in cardiology has had. Too, match progress in last 10 years. Both in hard were software. In echocardiography, perfusion scan . CT & MRI & newly in PET-CT.There has been. tremendous. Development & new era of better temporal & special resolution & more specific & more .sensitive diagnosis :In cardiac CT: development of 64 & higher slice. Defectors improved in resolution with more specific.Diagnostic accuracy. CCTA. has had. tremendous. Change in the diagnosis of CAD from invasive to. noninvasive modality Beside anatomic: Diagnosis in CCTA there is a growing body of evidence. Supports the use of functional computed. Tomography imaging, including myocardial stress CT perfusion & CT derived fractional flow reserve (FFRCT) for guiding clinical management in appropriately selected patients with suspected IHD. The two strategies are particularly valuable in patients with 50-70% stenosis detected in CCTA who has High calcification. or Stent artifact effect .In appropriately selected patents, CT perfusion and FFRCT have added values. In 1- Improvement in accuracy for. hemodynamically significant CAD 2- Safety and improvement in patient s outcome.3- Lower cost.4- Streamlined. diagnostic work flow
