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.

A 53-year-old male patient, suffering from severe emphysema and hyperinflation, was treated with endobronchial valve deposition – an interventional procedure aiming to reduce the lung volume in order to improve ipsilateral diaphragmatic motion and subsequently, the patient’s respiratory condition.

A 16-year-old female dog, suffering from a massive paraspinal mass on her left lower back for the past 6 months, was referred for palliative treatment as the mass was considered nonresectable due to its size and location.

A 68-year-old female patient, who had undergone a balloon pulmonary angioplasty (BPA) four months ago, returned to the hospital for her second scheduled treatment session. A dual energy chest CT was requested to evaluate the lung perfused blood volume (LungPBV) and the pulmonary arteries prior to treatment.

A 13-year-old boy, suffering from epigastric pain, nausea and vomiting, with aggravation after meals over the past three days, came to the hospital. An ultrasound examination revealed a large mass in the right hepatic lobe. A CT examination was performed for differential diagnosis.
