To evaluate the effectiveness of visualization vascularization at contrast material-enhanced ultrasonography (US) for assessment activity Crohn disease, with severity grade determined endoscopy as reference standard.Ethics committee approval and written informed consent were obtained. Sixty-one patients (age range, 21-67 years; median age, 36 years) who had disease underwent both colonoscopy US, including color Doppler contrast-enhanced prospectively. assess involved bowel loop in a region...
Abstract Purpose: To develop an automated segmentation method to differentiate the ventilated lung volume on 3 He magnetic resonance imaging (MRI). Materials and Methods: Computational processing (CP) for each subject consisted of following three essential steps: 1) inhomogeneity bias correction, 2) whole segmentation, 3) subdivision into regions similar ventilation. Evaluation two comparative analyses: i) comparison number defects scored by human readers in 43 subjects, ii) simultaneous...
The objective of our study was to evaluate the diagnostic performance dual-source dual-energy CT (DECT) in detection endoleaks after thoracic endovascular aortic repair for aneurysm and investigate if a double-phase (arterial late delayed phase) or single-phase (dual-energy acquisition can replace standard triphasic protocol.All DECT examinations performed evaluation during 30-month period were retrospectively reviewed. An initial single-source unenhanced followed by arterial phase...
Glioblastoma and solitary metastatic lesions can be difficult to differentiate with conventional MRI. The use of diffusion-weighted MRI better characterize peritumoral edema has been explored for this purpose, but the results have conflicting. purpose study was test hypothesis that gradient apparent diffusion coefficient (ADC) values in edema--that is, difference ADC from region closest enhancing tumor one normal-appearing white matter--may a marker differentiating glioblastoma lesion.Forty...
The aim of the study was to determine whether hyperpolarized He diffusion-weighted magnetic resonance imaging detects abnormalities in lungs children with bronchopulmonary dysplasia (BPD) as compared age-matched normal children.All experiments were compliant Health Insurance Portability and Accountability Act (HIPAA) performed Food Drug Administration approval under an IND application. protocol approved by our Institutional Review Board, written informed consent obtained. Hyperpolarized 16...

Purpose To determine the correlation between metabolic activity at fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET) and survival in patients with glioblastoma suspected progression posttherapy magnetic resonance (MR) imaging. Materials Methods The authors retrospectively examined relationship FDG PET residual lesion identified brain MR imaging time 56 who were treated postoperative concurrent radiation temozolomide therapy underwent PET/computed because of radiologic...
Aims Total bilirubin tests are individually inexpensive but can result in huge costs to healthcare systems worldwide, because they very commonly requested. The main objective of this study was evaluate the diagnostic accuracy icteric index, a test with zero reagent cost, as preliminary biomarker decide when total measurement is necessary. Methods We retrospectively reviewed all requested values and their corresponding index results 2-year period (2010–11). Receiver operating characteristic...
Objective: The development of liver fibrosis and cirrhosis due to long-standing congestion is known occur in adult patients with Fontan circulation. Hepatic elastography has shown be a useful tool for the noninvasive assessment staging chronic diseases, although utility this technique remains adequately studied. Methods: Twenty-one circulation underwent an abdominal ultrasound acoustic radiation force impulse (ARFI) elastography. In order compare results from group, cohort 14 healthy...
Background Traumatic brain injury (TBI) is the leading cause of disability in young adults. Recurrent TBI associated with a range neurologic sequelae, but contributing factors behind development such chronic encephalopathy are poorly understood. Purpose To quantify early amyloid β deposition otherwise healthy adult men exposed to repeated subconcussive blast using PET. Materials and Methods In this prospective study from January 2020 December 2021, military instructors who were routinely...
The existing tools to quantify lung function in interstitial diseases have significant limitations. Lung MRI imaging using inhaled hyperpolarized xenon-129 gas (129Xe) as a contrast agent is new technology for measuring regional physiology. We sought assess the utility of 129Xe detecting impaired physiology usual pneumonia (UIP). After institutional review board approval and informed consent compliance with HIPAA regulations, we performed chest CT, pulmonary tests (PFTs), 10 UIP subjects...
