A 62-year-old male patient with severe symptomatic low-flow, low-gradient aortic stenosis was scheduled for transcatheter aortic valve replacement. A coronary CT angiography was performed prior to the procedure, using an ultra-high resolution scan mode due to the patient’s high coronary calcium load.

The improved resolution offered by photon-counting technology is a game changer for neurologists at Erasmus Medical Center Rotterdam, says lead researcher Professor Aad van der Lugt.

A 60-year-old female patient with severe obesity (300 kg body weight) was admitted to the hospital due to sepsis and acute renal failure.
