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®.
A 67-year-old male patient underwent a left internal carotid artery stent angioplasty. Following a successful procedure, he developed right hemiparesis and dysarthria. Dual Energy brain CT without i.v. contrast was performed to rule out a suspected subarachnoid bleeding.
A 61-year-old male patient, suffering from a renal cell carcinoma (RCC), underwent a CT examination for staging. A small lung nodule was detected, suspicious of a metastasis. The patient was admitted for a biopsy of the lesion under CT guidance.
A 64-year-old male patient, complaining of atypical chest discomfort during exercise and palpitations at rest, presented himself to the hospital. A coronary CT angiography was performed on a Dual Source photon-counting CT, NAEOTOM Alpha®, using a Quantum HD cardiac mode to rule out exercise-induced coronary insufficiency.
A 58-year-old female patient with a 10-year history of migraine, tinnitus and orthostatic headache, was diagnosed of spontaneous intracranial hypotension. CT myelography was performed on a photon-counting CT, NAEOTOM Alpha®, using a UHR scan mode to identify and localize the suspected cerebrospinal fluid-venous fistula prior to a definitive treatment.
A 9-year-old boy, suffering from frequent urination, weak stream and enuresis, was presented to the hospital for a check-up. Ultrasonography and cystoradiography revealed hydronephrosis and hydroureter on the right side, accompanied by multiple stones in the distal ureter. An abdominal contrast CT examination was requested for further evaluation.
