OBJECTIVES To prospectively verify, in vivo, Le Bihan's model of signal decay in magnetic resonance/diffusion-weighted imaging (intravoxel incoherent motion) in healthy liver parenchyma. METHODS Informed consent and institutional board approval were obtained. To measure both underfasting and postprandial conditions, apparent, slow, and fast diffusion (D*)(More)
OBJECTIVE In cone beam CT (CBCT), imperfect patient immobility, caused by involuntary movements, is one of the most important causes of artefacts and image quality degradation. Various works in literature address this topic, but seldom is the nature of the movement correlated with the type of artefact and the image degradation in a systematic manner, and(More)
OBJECTIVE The aim of this work was to analyze the value of diffusion-weighted imaging (DWI) in the classification/characterization of focal liver lesions (FLLs). METHODS Retrospective study, approved by ethical board, of 100 proven FLLs (20 hemangiomas, 20 focal nodular hyperplasia, 20 dysplastic nodules, 20 hepatocellular carcinomas, and 20 metastases)(More)
Dear Editor, A 63-year-old man underwent CT studies before surgery for an aortic aneurysm. Contrast medium-enhanced CT scan showed an increased spleen size with a solid, 10 cm large, round, well-defined highly enhanced lesion, suggesting high vascularity with nonhomogeneous density due to the presence of some pseudocystic areas (Fig. 1a) [1]. An increased(More)
