SPEQUA

The SPEQUA study is the second in-vivo study after CAPL. It aims at demonstrating the improvement of image quality in SPCCT compared to a standard dual energy scanner (IQon/Hawk) used in radiology at the Louis Pradel Cardiologic Hospital. 

This is a prospective study, i.e. patients are included specifically for this study.

For this purpose, different pathologies are targeted: diabetes, coronary diseases, pneumopathies, adrenal glands lesions, urinary stones, strokes, cerebral arteriovenous malformations, articular lesions.

Each patient included in the study will first undergo a conventional DECT scan and then a SPCCT scan from 1 hour to 8 days after if the scans are non-injected and between 4 hours to 8 days if the scans are injected.

A total of 216 patients are expected in this study.

This work has been the subject of two publications, one of which will be published in the international journal RADIOLOGY.
