CardIQ™ Xpress / Clinical Case

Clinical Case

A 68-year old man with an atypical chest pain and a normal ECG was referred to a cardiac CT exam to have a complete heart study. The cardiac CT exam demonstrated a stenosis in the LAD.

Time Study

Cardiac CT post-processing can be a time consuming exam.Time measurements were made with 10 different patients to evaluate the workflow improvement of the new software CardIQ™ Xpress Pro.For each case, a complete heart study has been performed.

The CardIQ™ Xpress software was designed to accelerate the post-processing by improving the workflow. In this study,it took less than 20 mn to perform a complete heart study and less than 10 mn to examine all the coronary arteries.


Conclusion

The conclusion from this study is that CardIQ™ Xpress accelerates the post-processing by up to 27% for the vessel analysis and allows the radiologist to spend more time discussing the diagnosis and the treatment with other doctors. The focus is on the patient. The radiologist can do the post-processing and the diagnosis of an exam in real time that allows cardiac CT to become a routine activity.
