Optimization of Radiation Dose in Cranial Computed Tomography among Adults: Assessment of Radiation Dose against Image Quality
Introduction: The rapid use of computed tomography (CT) scan is of great concern, due to increase in patients’ dose. Optimization of CT protocol is a vital issue in dose reduction. This study aimed to optimize radiation dose in cranial CT and assess modifications in image quality under radiation dose reduction. Material and Methods: A poly(me...
متن کاملDose Reduction Methods in Chest Computed Tomography
Introduction: Computed tomography is one of the most powerful tools for investigating thorax disease, because it shows progression of lung disease much clearer than chest radiography. Technical advances in CT scanners have led to some abilities for CT scanners such as coverage of larger volume, lower noise and ability for acquiring image in one respiratory phase. However, this will be accompani...
متن کاملDose Reduction on Computed Tomography Angiography Using Adaptive Control Techniques
With the advent of multi-slice computed tomography (CT) scanner and the sophisticated CT reconstruction algorithm, CT Angiography (CTA) is increasingly used to evaluate patient with vascular diseases (Fleischmann et al., 2006; Chow & Rubin, 2002; Rubin at al., 2001). It has many advantages over the conventional catheter angiograms: 1) non-invasiveness, 2) short acquisition time, 3) multiple vie...
متن کاملRadiation dose reduction in pediatric great vessel stent computed tomography using iterative reconstruction: A phantom study
BACKGROUND To study dose reduction using iterative reconstruction (IR) for pediatric great vessel stent computed tomography (CT). METHODS Five different great vessel stents were separately placed in a gel-containing plastic holder within an anthropomorphic chest phantom. The stent lumen was filled with diluted contrast gel. CT acquisitions were performed at routine dose, 52% and 81% reduced d...
متن کاملReducing computed tomography radiation dose in diagnosing pulmonary embolism
BACKGROUND AND OBJECTIVE Computed tomography angiography plays a major role in the diagnosis of pulmonary embolism. Radiation dose associated with it is a major concern; therefore it is important to optimize protocols and techniques to ensure minimum radiation dose. METHODS The study compares two protocols i. Conventional Timing Bolus CT protocol and Delayed Timing Bolus protocol used to assi...
