Diagnostic accuracy of ultra-high resolution coronary CT angiography using photon-counting CT
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.
Scaphoid fracture only seen in CT
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).

A 62-year-old female obese patient, with a history of arterial hypertension and hyperlipidemia, presented to the institutional chest pain unit with typical angina and an extensive cardiovascular risk profile. A coronary CT angiography was performed using a dual source photon-counting detector (PCD) CT (NAEOTOM Alpha®) in ultra-high resolution (UHR) mode.
Photon-counting CT for coronary assessment: real world results in heart transplant patients
Presented by Assoc. Prof. Olivier Manintveld, MD, and Prof. Ricardo Budde, MD, Erasmus Medical Center, at ECR 2023, in a Corporate Symposium “Pushing the boundaries of CT imaging with photon-counting technology”.
A 64-year-old female patient with a history of metastatic clear cell renal cell carcinoma came to the hospital due to a novel lesion found in the pancreatic head, which partially obstructed the portal vein, raising the concern of either tumor invasion or thrombus formation. A contrast-enhanced CT scan was requested and performed on a photon-counting CT.

A 76-year-old female patient had an incidental CT finding of a pancreatic cystic lesion 6 years ago. Recently, the lesion showed a slight increase in size. An endoscopic ultrasound examination was performed; however, the cytological analysis was inconclusive. Further assessment was requested by contrast-enhanced CT.

Stapes prosthesis dislocation
A 74-year-old female patient, with a history of bilateral stapedectomy and stapes prosthesis insertion 10 years ago, came to the hospital complaining of a progressive, worsening conductive hearing loss on the left side for over the past 2 years. A CT examination using a ultra-high resolution (UHR) scan mode was performed for evaluation.
Photon-counting CT – cardiovascular imaging
Presented by Prof. Dr. Ricardo Budde, Radiology and Nuclear Medicine, Erasmus MC, Rotterdam, The Netherlands, at RSNA 2022, in a Corporate Symposium “In the new era of medical imaging: Real-world results from Photon-counting CT”.
Metastatic pulmonary adenocarcinoma – complicated by PE?
A 51-year-old male patient, suffering from pulmonary adenocarcinoma with metastases, had
undergone chemotherapy as well as immunotherapy. A contrast chest and abdomen CT examination was requested for a follow-up evaluation of treatment response.
Photon-counting CT – added value in thoracic imaging

Preoperative evaluation in a case of Tetralogy of Fallot
A 5-month-old baby was born with heart murmurs. An echocardiogram revealed a suspected Tetralogy of Fallot. The patient was admitted to the hospital for surgical repair. A cardiac CT angiography was requested for preoperative evaluation.
