Dose 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 کاملEvaluation of suspected renal colic patients with unenhanced low-dose multi-detector computed tomography.
OBJECTIVES To determine the proportion of correctly diagnosed ureteric calculi and alternate diagnoses using unenhanced low dose multidetector CT KUB. DESIGN Descriptive - prospective study. SETTING Aga Khan University Hospital, Nairobi between November 2006 and October 2007. SUBJECTS One hundred and four patients underwent low dose multi-detector computed tomography (MDCT) KUB. RESULTS...
متن کاملComputed tomography dose optimization.
Use of computed tomography (CT) as a medical diagnostic imaging tool has increased in recent decades because of its technical advances in data acquisition speed and image reconstruction technology. The increased reliance on CT was accompanied by increased patient exposure to ionizing radiation, however, and concerns among radiologic professionals and the public regarding CT dose resulted in inc...
متن کاملReduction of uterus dose in clinical thoracic computed tomography.
PURPOSE The aim of this study was to investigate the potential dose reduction in the uterus as a result of lead apron protection during thoracic CT scans. Moreover, the distribution of the radiation dose in the uterus was determined in order to obtain information about the ratio of internally and externally scattered radiation. MATERIALS AND METHODS The uterus doses during thoracic CT were de...
متن کاملLow-dose unenhanced computed tomography for diagnosing stone disease in obese patients
OBJECTIVE To evaluate the detectability, size, location and density of urinary stones with unenhanced computed tomography (CT), using the half-radiation (low) dose (LDCT) technique, compared with the standard-dose CT (SDCT), in obese patients. PATIENTS AND METHODS The study included 50 patients with a body mass index of >30 kg/m(2) and bilateral renal stones diagnosed with SDCT, and managed o...
