Computed Tomography News & Stories

A 63-year-old female patient, with a history of Hypoglycemia, had a calcium stimulation challenge test which showed diffuse insulin secretion throughout the pancreas, suspecting an insulinoma. However, a conventional CT examination did not reveal any pancreatic lesion. A contrast CT scan was performed with NAEOTOM Alpha for further evaluation.

A 59-year-old male patient, with a history of triple CABG and coronary stenting, came to the hospital with non-specific symptoms. A CT scan with a dual source photon-counting detector CT, NAEOTOM Alpha®, was performed to evaluate the patency of the grafts, the anastomoses and the stent.

A 69-year-old male patient, complaining of abdominal pain slowly progressing over the past 3 months, came to the hospital for a check-up. Ultrasound examination revealed a mixed solid and cystic mass in the pancreatic body, with suspicious invasion into the gastric wall. A CT examination was performed with a photon-counting CT, NAEOTOM Alpha®, for further assessment.

A 78-year-old female diabetic patient, with clinical symptoms of a suspected stable angina, came to the hospital for a check-up. A coronary CT angiography was requested to evaluate the coronary arteries and to rule out coronary stenosis. A prospectively ECG-triggered sequential mode was performed with a dual source photon-counting detector CT, NAEOTOM Alpha®.

A 60-year-old male patient, complaining of intermittent chest pain and shortness of breath for the past month, came to the hospital for a check-up. He had a history of coronary stenting. A CCTA was requested and performed with a dual-source photon-counting CT, NAEOTOM Alpha^®, to assess the coronaries and the stent patency.

A 70-year-old female patient, suffering from hypertension, came to the hospital complaining of increasing chest discomfort suspicious of angina. Coronary CT angiography was requested and performed on a dual source CT, a SOMATOM Pro.Pulse, to rule out obstructive coronary disease.

A 76-year-old male patient, with a history of coronary stenting, was presented to the hospital, complaining of palpitations and chest tightness. An ECG-triggered sequential ultra-high resolution CCTA with a dual source photon-counting detector (PCD) CT, NAEOTOM Alpha^®, was performed to assess the coronary arteries and the patency of the stents.

A 46-year-old male patient, with a history of CABG and coronary stenting, presented himself to the hospital due to atypical chest pain. A CT scan was requested to evaluate the patency of the grafts, the anastomoses and the stents. A UHR coronary CT angiography was performed on a dual-source photon-counting detector CT, NAEOTOM Alpha®.

A 76-year-old male patient suffered from repeated episodes of renal colic associated with hematuria. Two native CT scans to detect renal calculi were negative. Urine cytology analysis to detect urothelial cancer also resulted negatively. A contrast enhanced CT scan was performed with a photon-counting CT, NAEOTOM Alpha®, for further assessment.

A 48-year-old male patient, suffering from a Non-ST-Elevation Myocardial Infarction, underwent percutaneous coronary intervention with multi-vessel coronary stent implantations two years ago. This unexpected incident had profoundly affected his life, causing substantial stress, and even panic attacks leading to several emergency department visits.

An 85-year-old male patient, suffering from bronchial carcinoma, was diagnosed with a left adrenal mass. It was progressive in size, despite prior radiotherapy, therefore being highly suggestive of a metastasis. The patient was admitted for cryoablation.

A 71-year-old female patient, suffering from paroxysmal atrial fibrillation, had undergone an uneventful transcatheter pulmonary vein radiofrequency catheter ablation in all 4 pulmonary veins along with left atrium appendage closure. 58 days later, a contrast-enhanced ECG-triggered cardiac CT was performed as a follow-up evaluation.

A 46-year-old male patient underwent pseudarthrosis revision due to a comminuted tibia fracture. 6 weeks later, a follow-up CT examination was scheduled to evaluate the status of osseous healing. A scan in ultra-high resolution mode with spectral shaping (tin filtration) was performed on a photon-counting CT, NAEOTOM Alpha®.

A 22-year-old female patient, suffering from tarsal coalition, was scheduled for surgery. CT was performed to evaluate the size, location and extent of the coalition for preoperative workup. An ultra-high resolution scan mode was performed on a photon-counting CT, NAEOTOM Alpha®.
