Comparison of free breathing versus breath-hold in perfusion imaging using dynamic volume CT
OBJECTIVES To compare two scanning protocols (free breathing versus breath-hold) for perfusion imaging using dynamic volume computed tomography (CT) and to evaluate their effects on image registration. MATERIAL AND METHODS Forty patients underwent dynamic volume CT for pancreatic perfusion analysis and were randomly assigned to either a shallow-breathing (I) or breath-hold (II) group. Both dy...
متن کاملAssessment of pulmonary perfusion with breath-hold and free-breathing dynamic contrast-enhanced magnetic resonance imaging: quantification and reproducibility.
OBJECTIVES The purpose of this study was to investigate whether quantification of pulmonary perfusion from dynamic contrast-enhanced magnetic resonance imaging (DCE MRI) yields more reproducible results with data acquired during free breathing than with data from conventional breath-hold measurements. MATERIAL AND METHODS Ten healthy male volunteers underwent 2 imaging sessions at a clinical ...
متن کاملComparison of liver ADC measurements using breath-hold, free breath-hold and respiratory gating echoplanar diffusion-weighted imaging sequences using parallel imaging technique with different acceleration factors
Introduction: Echoplanar diffusion-weighted images (EP-DWI) with breath holding (BH) have been widely applied to evaluate the apparent diffusion coefficient (ADC) of liver. Clinically, the spatial coverage of DWI is usually limited by the duration (around 20 seconds) of breath hold. Free breathing (FB) and respiratory gating (RG) methods allow larger spatial coverage of liver in one scan. Compa...
متن کاملFree-breathing Imaging Techniques for Liver Iron Quantification: Comparison with a Validated Breath-hold Technique in Patients with Iron Overload
Introduction: Hepatic iron content (HIC) measurements utilizing quantitative T2* maps have become an increasingly used alternative to traditional HIC evaluation obtained by liver biopsy. The advantages of T2* based HIC measurements are the non-invasive nature of the precedure and a relatively short measurement time. Recently several studies were presented, that correlated biopsy based HIC measu...
