HD Cardiac Imaging
Performances in calcium blooming reduction, stent visualisation and in stenosis assessment may allow for diagnostic accuracy and are important parameters that may affect the positive predictive value.
With a cardiac spatial resolution of 18.2lp/cm, the Discovery CT750 HD FREEdom Edition is the industry leader in cardiac spatial resolution1.
The resolution of the Discovery CT750 HD FREEdom Edition is important for reduction in calcium blooming compared to standard resolution, giving clearer images for a confident diagnosis. It may also help you accurately quantify stenosis in coronary vessels.

Low Dose Cardiac Imaging
SnapShot Pulse and ASiR* enable low dose not only for Coronary CT but across cardiovascular exams, enabling cardiac CT of less than 1mSv. Using SnapShot Pulse imaging and ASiR, the Discovery CT750 HD FREEdom Edition achieves a dose reduction of greater than 83% compared to gated helical acquisition.2,3,4
2. In clinical practice, the use of ASiR may reduce CT patient dose depending on the clinical task, patient size, anatomical location and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.
3. Dose reduction was measured on a standard 20cm water phantom comparing a SnapShot Pulse prospective gated axial acquisition at 120kV/300mA and 50% ASiR to a cardiac helical acquisition 120kV/500mA without ASiR both with a 224mm scan coverage.
4. In clinical practice, the use of SnapShot Pulse may reduce cardiac CT patient dose depending on the clinical task and patient heart rate. A consultation with a radiologist should be made to determine the appropriate acquisition mode and scan settings to obtain diagnostic image quality for the particular clinical task.
