To determine whether acute transient dyspnea and/or arterial phase image degradation occurs more or less often after intravenous administration of gadoxetate disodium than with gadobenate dimeglumine.Institutional review board approval and patient consent were obtained for this prospective observational study. One hundred ninety-eight gadolinium-based contrast media administrations (99 [10 mL, n = 97; 8 1; 16 1] 99 dimeglumine [0.1 mmol per kilogram body weight, maximum dose, 20 mL])...
To determine for expert and novice radiologists repeatability of major diagnostic features scoring systems (ie, Liver Imaging Reporting Data System [LI-RADS], Organ Procurement Transplantation Network [OPTN], American Association the Study Diseases [AASLD]) hepatocellular carcinoma (HCC) by using magnetic resonance (MR) imaging.Institutional review board approval was obtained patient consent waived this HIPAA-compliant, retrospective study. The LI-RADS discussed in article refers to version...
OBJECTIVE. The purpose of this article is to evaluate the accuracy dual-energy CT in distinguishing enhancing from nonenhancing or equivocally renal lesions.
To compare frequency and severity of arterial phase respiratory motion-related artifact following gadoxetate disodium gadobenate dimeglumine in matched patients administered both contrast media at different times.Institutional review board approval was obtained, with patient consent waived, for this retrospective, HIPAA-compliant study. Ninety underwent dimeglumine-enhanced abdominal magnetic resonance (MR) followed by disodium-enhanced MR were to 90 who the same reverse order (180...
Recent advances in computed tomographic (CT) scanning technique such as automated tube current modulation (ATCM), optimized x-ray voltage, and better use of iterative image reconstruction have allowed maintenance good CT quality with reduced radiation dose. ATCM varies the during to account for differences patient attenuation, ensuring a more homogeneous quality, although selection appropriate parameter is essential achieving optimal dose reduction. Reducing voltage best suited evaluating...
The objective of our study was to evaluate the image quality and diagnostic adequacy following two CT enterography protocols in patients weighing less than 160 lb (72 kg): 80-kVp imaging with adaptive statistical iterative reconstruction (ASIR) comparison 120-kVp filtered back projection reconstruction.We retrospectively reviewed 133 examinations 127 lb, 64 examinations, 69 examinations. Image for evaluation bowel wall, mesenteric vessels, hepatic parenchyma overall were graded on a scale...
Objective To assess endoleak detection and conspicuity using low–kiloelectron volt (keV) monochromatic reconstructions of single-source (fast-switch kilovolt [peak]) dual-energy data sets. Methods With approval the institutional review board, multiphasic computed tomographic (CT) scans for aortic endograft surveillance were retrospectively reviewed 39 patients. Two abdominal radiologists each performed 2 separate reading sessions, at 55-keV standard 75-keV reconstruction, respectively. The...
Purpose In 90 Y microsphere radioembolization ( RE ), accurate post‐therapy imaging‐based dosimetry is important for establishing absorbed dose versus outcome relationships developing future treatment planning strategies. Additionally, accurately assessing distributions because of concerns unexpected activity deposition outside the liver. Quantitative imaging by either SPECT or PET challenging. model based methods are necessary scatter correction energy window‐based not feasible with...

The aim of this work was to develop models for tumor control probability (TCP) in radioembolization with <sup>90</sup>Y PET/CT–derived radiobiologic dose metrics. <b>Methods:</b> Patients primary liver cancer or metastases who underwent glass microspheres were imaged PET/CT voxel-level dosimetry determine lesion absorbed (AD) metrics, biological effective (BED) equivalent uniform dose, and BED 28 treatments (89 lesions). dose–shrinkage correlation assessed on the basis RECIST and, when...
The purpose of this article is to evaluate single-source dual-energy CT (DECT) for distinguishing benign and indeterminate adrenal nodules, with attention the effects phase IV contrast enhancement.A retrospective review revealed 273 contrast-enhanced abdominal DECT examinations from November 2009 through March 2012. Fifty nodules 0.8 cm or larger were identified in 41 patients (22 women 19 men; average age, 66 years; age range, 36-88 years). postprocessing measurements independently...
This is the fourth of a series 4 white papers that represent expert consensus documents developed by Society Computed Body Tomography and Magnetic Resonance through its task force on dual-energy computed tomography. article, part 4, discusses DECT for abdominal pelvic applications and, at end each, will offer our opinions current clinical utility application opportunities further research.
The objective of our study was to evaluate image quality and overall adequacy low-dose CT angiography (CTA) with model-based iterative reconstruction (MBIR) in patients who had undergone endovascular aneurysm repair (EVAR) a thoracic or abdominal aortic aneurysm.Thirty patients, all whom standard-dose CTA performed previously adaptive statistical (ASIR), underwent for surveillance after EVAR. Two radiologists randomly evaluated both studies, parameters were assessed. maximal diameter...
