Ultrahigh-resolution photon-counting CT (PCCT) pulmonary angiography improves not only image quality but also reader confidence, German researchers have found.
Presenter Pauline Pannenbecker, MD, of the University Hospital of Würzburg will report on a study she conducted with colleagues that evaluated the impact of using ultrahigh-resolution PCCT on image quality and reader confidence in spectral CT pulmonary angiographies (CTPA) compared with standard resolution dual-energy CTPA with energy-integrating detector CT. The study included 32 CTPAs performed using PCCT and 32 performed with conventional CT. Both types of exams used 50 ml of contrast; the team set the pitch for the PCCT exams at 3.2 and for the conventional CT exams at 0.55. Four readers used a five-point scale to assess the CTPA images.
The team found no difference in attenuation between the PCCT and conventional CT CTPAs, and three of the four readers rated subjective image quality higher on the PCCT exams. Stop by the Learning Center to find out more about their results.
