| 1 | Gastrointestinal imaging-practical magnetic resonance imaging approach显示文摘Over the past two decades, advances in cross-sectionalimaging such as computed tomography and magneticresonance imaging(MRI) have dramatically changed theconcept of gastrointestinal imaging. MR is playing anincreasing role in the evaluation of gastrointestinal disorders. MRI combines the advantages of excellent soft-tissue contrast, noninvasiveness, functional informationand lack of ionizing radiation. Furthermore, recent developments of MRI have led to improved spatial and temporal resolution as well as decreased motion artifacts. Inthis article we describe the technical aspects of gastroin-testinal MRI and present a practical approach for a well-known spectrum of gastrointestinal disease processes. | Baodong Liu Miguel Ramalho Mamdoh AlObaidy Kiran K Busireddy Ersan Altun Janaka Kalubowila Richard C Semelka | 2014 | World Journal of Radiology2014，6，8： | 11 |
| 2 | Pancreatitis-imaging approach显示文摘Pancreatitis is defined as the inflammation of the pancreas and considered the most common pancreatic disease in children and adults. Imaging plays a significant role in the diagnosis, severity assessment, recognition of complications and guiding therapeutic interventions. In the setting of pancreatitis, wider availability and good image quality make multi-detector contrastenhanced computed tomography(MD-CECT) the most used imaging technique. However, magnetic resonance imaging(MRI) offers diagnostic capabilities similar to those of CT, with additional intrinsic advantages including lack of ionizing radiation and exquisite soft tissue characterization. This article reviews the proposed definitions of revised Atlanta classification for acute pancreatitis, illustrates a wide range of morphologic pancreatic parenchymal and associated peripancreatic changes for different types of acute pancreatitis. It also describes the spectrum of early and late chronic pancreatitis imaging findings and illustrates some of the less common types of chronic pancreatitis, with special emphasis on the role of CT and MRI. | Kiran K Busireddy Mamdoh AlObaidy Miguel Ramalho Janaka Kalubowila Liu Baodong Ilaria Santagostino Richard C Semelka | 2014 | World Journal of Gastrointestinal Pathophysiology2014，5，3： | 4 |
