Background: In the current COVID-19 pandemic, there is a rising need for a rapid and reliable diagnostic tool. We hypothesized that chest computed tomography (CT) can be a potential alternative for reverse transcription-polymerase chain reaction (RT-PCR). The aim of this study was to compare the diagnostic value of chest CT and RT-PCR in Iranian patients with suspected COVID-19. Methods: In a...

Introduction Organ-based tube current modulation (OBTCM) is designed for anterior dose reduction in Computed Tomography (CT). The purpose was to assess capability chest CT using three organ systems at different kVp settings. Furthermore, noise, diagnostic image quality and tumour detection assessed. Methods A Lungman phantom scanned with without OBTCM 80–135/140 scanners; Canon Aquillion Prime,...

OBJECTIVES The aim of this phantom study was to minimize the radiation dose by finding the best combination of low tube current and low voltage that would result in accurate volume measurements when compared to standard CT imaging without significantly decreasing the sensitivity of detecting lung nodules both with and without the assistance of CAD. METHODS An anthropomorphic chest phantom con...

Introduction: The study aimed to assess absorbed and effective doses in organs through computed tomography (CT) examinations using automatic exposure control (AEC) and fixed tube current (FTC) techniques. Material and Methods: Scanning parameters were obtained for routine adult CT examinations and used to estimate the organ absorbed and effec...

OBJECTIVE Pleural effusions are a frequent complication of malignancy and cause considerable morbidity from dyspnea. The drainage and control of malignant effusions relieve symptoms and maintain quality of life but these are difficult in patients with multiloculated effusions in whom drainage usually fails. This observational series reports the use of intrapleural streptokinase (IPSK) in the ma...

PURPOSE An initial description of a sonographic finding predictive of intrathoracic chest tube placement. METHODS This was a prospective observational study using unembalmed cadaveric models. Chest tubes were randomly placed intra- and extrathoracically and evaluated using ultrasound. Chest tube location was confirmed using blunt dissection followed by tactile and visual confirmation. Sonogra...

BACKGROUND Evaluation of latest generation automated attenuation-based tube potential selection (ATPS) impact on image quality and radiation dose in contrast-enhanced chest-abdomen-pelvis computed tomography examinations for gynaecologic cancer staging. METHODS This IRB approved single-centre, observer-blinded retrospective study with a waiver for informed consent included a total of 100 pati...
