The efficiency and radiation dose of a low-dose dual-energy (DE) CT protocol for the evaluation of urinary calculus disease were evaluated. Read more

The potential of dual energy computed tomography (DECT) for the analysis of gallstone compounds was investigated. The main goal was to find parameters, that can reliably define high percentage (> 70 %) cholesterol stones without calcium components. Read more

Purpose: To assess the diagnostic performance of dual-energy dual-source computed tomography (CT) in the detection of endoleaks after endovascular abdominal aortic aneurysm (AAA) repair. Materials and Methods: This study was local ethics board approved, and written informed consent was obtained from all patients. One hundred eighteen patients (21 women, 97 men; mean age, … Read more

Case history 66-year-old male presents with gallbladder lesion. Multiple MRI scans and ultrasound scans were not able to definitively conclude the nature of the lesion. Question Can CT differentiate between cholesterol rich gallstone and polyp? Could the … Read more

The following question has been sent by Sofiane Hadjadj, MD, clinical research, Canada: For the diagnosis and follow-up of aortic aneurysms the aortic ECG guating ct scan have shown it accuracy beside echo, we still no have concensus about which phase we should measure the aortic diameters, some surgeons here prefere … Read more
