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.
A 28-year-old female patient, suffering from a sudden onset of heart palpitation accompanied by atypical chest pain, was admitted to the emergency room. The patient reported no previous episode and her medical history was unremarkable. A chest CT angiography (CTA) was requested to rule out associated anomalies.
Inside an incidental solid renal mass
An 89-year-old male patient, complaining of unspecific abdominal pain and hematuria, came to the hospital for a checkup. Physical examination and laboratory tests suggested a prostatic hyperplasia as the cause of hematuria. An abdominal contrast CT scan was performed on a dual source photon-counting CT, NAEOTOM Alpha®, to rule out any other potential cause.
