Computed Tomography

A 22-month-old girl with a cardiac murmur was diagnosed with congenital heart disease and admitted for surgical repair. A pulmonary CTA was requested for preoperative evaluation.

A 20-year-old male patient with a FOOSH injury underwent a screw fixation of the scaphoid and later, a revision surgery due to non-union of the fracture. A follow-up CT showed unclear bone structure around the screw with the presence of metal artifacts. Further evaluation was performed using a UHR scan mode on a photon-counting CT (NAEOTOM Alpha®).

A 13-year-old female patient,  with left elbow complaints for the past 18 months, had a radiograph of the elbow which showed a suspicious osteochondritis dissecans of the capitellum. For further evaluation, an ultra-high resolution scan mode on a photon-counting CT scanner (NAEOTOM Alpha®) was requested.

The NAEOTOM Alpha®, a newly developed dual-source CT scanner with photon-counting detectors (QuantaMax®), has the potential to address some of the challenges of cCTA. It provides energy-resolved CT data without electronic noise at improved spatial resolution.

A 14-year-old girl presented herself to the emergency department due to a fall onto her outstretched right hand. Radiographs performed revealed only equivocal result. A CT scan was requested for further evaluation, using an ultra-high resolution mode on a photon-counting CT scanner (NAEOTOM Alpha).
