Individual and Contextual Variables as Predictors of MRI-Related Perceived Anxiety.

Background: Magnetic resonance imaging (MRI) generates patient anxiety (PA) and, therefore, it is important to understand individual and contextual variables that may cause it. In study one, we explored those anxiety predictors. In study two, we examined the effect of the experience of MRI on PA comparing anxiety pre- to post-MRI.

Imaging evaluation of the liver in oncology patients: A comparison of techniques.

The liver is commonly affected by metastatic disease. Therefore, it is essential to detect and characterize liver metastases, assuming that patient management and prognosis rely on it. The imaging techniques that allow non-invasive assessment of liver metastases include ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET)/CT, and PET/MRI.

Multidetector computer tomography: evaluation of blunt chest trauma in adults.

Imaging plays an essential part of chest trauma care. By definition, the employed imaging technique in the emergency setting should reach the correct diagnosis as fast as possible. In severe chest blunt trauma, multidetector computer tomography (MDCT) has become part of the initial workup, mainly due to its high sensitivity and diagnostic accuracy of the technique for the detection and characterization of thoracic injuries and also due to its wide availability in tertiary care centers.

Post-contrast T1-weighted sequences in pediatric abdominal imaging: comparative analysis of three different sequences and imaging approach.

Background: Post-contrast T1-weighted imaging is an essential component of a comprehensive pediatric abdominopelvic MR examination. However, consistent good image quality is challenging, as respiratory motion in sedated children can substantially degrade the image quality.

Objective: To compare the image quality of three different post-contrast T1-weighted imaging techniques-standard three-dimensional gradient-echo (3-D-GRE), magnetization-prepared gradient-recall echo (MP-GRE) and 3-D-GRE with radial data sampling (radial 3-D-GRE)-acquired in pediatric patients younger than 5 years of age.

Perilesional enhancement of liver cavernous hemangiomas in magnetic resonance imaging.

Objective: To evaluate on magnetic resonance imaging (MRI) the occurrence rate of temporal perilesional parenchymal enhancement (PPE) associated with hepatic hemangiomas in a large consecutive series and to determine which aspects are associated with this observation.

Materials And Methods: Institutional review board approved this retrospective study. A computerized search of the MRI database was performed for consecutive patients between January 2008 and January 2012.

MRI of pregnant patients for suspected pulmonary embolism: steady-state free precession vs postgadolinium 3D-GRE.

Introduction: Pulmonary embolism is a leading cause of maternal mortality in the developed world. Ventilation-perfusion scintigraphy and Computer tomography cause ionizing radiation exposure. Gadolinium-enhanced magnetic resonance imaging is generally not indicated in pregnant patients.

Heart extension of an intravenous leiomyomatosis.

Intravenous leiomyomatosis is a rare growth pattern of benign uterine leiomyomas. Approximately 300 cases of intravenous leiomyomatosis have been reported in the English literature; however, there have only been a few in radiology journals. Even more rare is its extension through the inferior vena cava and heart chambers.

Hepatic sarcoidosis: MR appearances in patients with chronic liver disease.

Purpose: To describe the MR appearances of hepatic sarcoidosis in patients with chronic liver disease and correlate the results with clinical stage of disease as measured with the Mayo end-stage liver disease (MELD) score.

Materials And Methods: Twenty patients with chronic liver disease and histopathological diagnosis of hepatic sarcoidosis who underwent MR imaging were included in this study. Two abdominal radiologists retrospectively reviewed all images for the presence of cirrhosis, imaging pattern of the liver, intrahepatic biliary dilatation, presence of areas of parenchymal atrophy, presence of splenic nodules and lymphadenopathy.

Magnetic resonance imaging of small bowel Crohn's disease.

Crohn's disease (CD) is a chronic relapsing inflammatory disease of the gastrointestinal tract, which mostly affects young patients. Imaging techniques form a very important part for the evaluation of CD and for monitoring disease progression or response to therapy. Currently, imaging of CD is increasingly being performed by cross-sectional modalities, i.
