conclusion the designed split-bolus mdct technique can be proposed alternatively to triphasic mdct and in a single-pass to pvp in the initial staging and in the follow-up respectively in oncologic patients. patients and methods we retrospectively analyzed the follow-up split-bolus 64-detector row ct protocol in 36 oncologic patients to characterize focal liver lesions. the split-bolus mdct prot...

Background: Patient radiation doses from computed tomography (CT) are increasing due to the number of CT examinations performed every day. The aim of this study was assess and evaluate patient radiation doses for adult’s common CT examinations to derive local diagnostic guidance levels for common CT examinations. Materials and Methods: Volume and weighted computed tomography dose index (C...

PURPOSE This study evaluated the potential use of the computed tomography indices (CTI) on cone beam CT (CBCT) images for an assessment of the bone mineral density (BMD) in postmenopausal osteoporotic women. MATERIALS AND METHODS Twenty-one postmenopausal osteoporotic women and 21 postmenopausal healthy women were enrolled as the subjects. The BMD of the lumbar vertebrae and femur were calcul...

X-ray computed tomography (CT), introduced into clinical practice in 1972, was the first of the modern slice-imaging modalities. To reconstruct images mathematically from measured data and to display and to archive them in digital form was a novelty then and is commonplace today. CT has shown a steady upward trend with respect to technology, performance and clinical use independent of predictio...

CT (computerized tomography) scan memiliki sensitivitas dan spesifisitas paling baik dalam penegakan diagnosis ataupun prognosis pasien COVID-19. Namun, ketersediaan masih terbatas di Indonesia; foto x-ray toraks merupakan pilihan utama karena ketersediaannya yang lebih mudah serta hasil cepat. Beberapa sistem skoring menggunakan mulai banyak diteliti dikembangkan, antaranya Brixia score, simpl...

We demonstrate a tomographic imaging modality that uses pulsed terahertz (THz) radiation to probe the optical properties of three-dimensional (3D) structures in the far-infrared. This THz-wave computed tomography (T-ray CT) system provides sectional images of objects in a manner analogous to conventional CT techniques such as x-ray CT. The transmitted amplitude and phase of broadband pulses of ...

Composite materials are increasingly used to help in reducing the carbon footprint of transportation and upscaling renewable energy infrastructure that provides clean for future cities. However, inherent susceptibility fibre reinforced polymers impact damage results knock-down design is linked micro-mechanistic response material damage. In situ experimental high-resolution imaging techniques us...
