Double-Low Dose Protocol of Computed Tomography Pulmonary Angiography (CTPA) in the Diagnosis of Pulmonary Embolism: A Feasible Approach for Reduction of Both Contrast Medium and Radiation Doses
This article discusses a hot topic on double low-dose protocol of computed tomography pulmonary angiography (CTPA) in the diagnosis of pulmonary embolism, with a special focus on a recent paper published in the British Journal of Radiology about the feasibility of this technique. Three aspects will be discussed in this review: First, both kVp and contrast medium can be reduced without affecting...
متن کاملCTPA for clinically suspected pulmonary emboli in oncology patients
Aim Pulmonary embolism (PE) is a known cause of morbidity and mortality in oncology patients. Whilst much of the literature focuses on the detection of incidental PE in this cohort of patients (approximately 4%), little is written about the rate of positive CT Pulmonary Angiograms (CTPA) when PE is clinically suspected. We wanted to assess the rate of positive CTPA specifically amongst oncology...
متن کاملImage Quality of 256-Slice Computed Tomography for Coronary Angiography.
PURPOSE To assess the image quality of 256-slice computed tomographic angiography (CTA) and to identify possible impact factors associated with image quality. METHODS From November 2009 to January 2010, 506 patients underwent 256-slice CTA at our institute. A total of 451 patients were enrolled in our study, after 55 patients were excluded because of prior bypass surgery and stenting. CTA ima...
متن کاملCTPA protocol optimisation audit: challenges of dose reduction with maintained image quality.
AIM To assess computed tomography (CT) pulmonary angiography (CTPA) dose and image quality in a large teaching hospital, and subsequently, to optimise the protocol in order to reduce the dose without affecting image quality. MATERIALS AND METHODS Dose-length product (DLP), patient size, and objective quality parameters (contrast-to-noise ratio and signal-to-noise ratio on standardised levels)...
