INTRODUCTION Contrast-enhanced MR imaging is the method of choice for routine assessment of brain tumors, but it has limited sensitivity and specificity. We verified if the addition of metabolic, diffusion and hemodynamic information improved the definition of glioma extent and grade. METHODS Thirty-one patients with cerebral gliomas (21 high- and 10(More)
Lymphomas are a heterogeneous group of lymphoid malignancies, which can be broadly divided into non-Hodgkin Lymphomas (NHL) and Hodgkin lymphoma (HL) that display different patterns of biological behavior and response to treatment. Their incidence is still increasing and for this reason they require a lot of effort in scientific research. The management of(More)
PURPOSE This study evaluated the sensitivity of a 3.0-Tesla (T) magnetic resonance imaging (MRI) in measuring cerebral phenylalanine using proton magnetic resonance spectroscopy and in assessing MR-documented white-matter changes by means of diffusion studies (diffusion-weighted imaging, apparent diffusion coefficient map; diffusion tensor imaging) in(More)
The objective of this study was to evaluate the potential role of newly developed, advanced magnetic resonance (MR) imaging techniques (spectroscopy, diffusion and perfusion imaging) in diagnosing brain gliomas, with special reference to histological typing and grading, treatment planning and posttreatment follow-up. Conventional MR imaging enables the(More)
PURPOSE Our aim was to assess the overall diagnostic accuracy of magnetic resonance diffusion-weighted whole-body imaging with background signal suppression (MR-DWIBS) compared with ([(18)F]-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT), considered the reference standard of whole-body tumour imaging modalities, in a(More)
The purpose of this study was to evaluate the sonographic features of thyroid nodules suspicious for malignancy with standard examination in B-mode and Color Doppler associated with modern techniques such as ultrasound RTE (Real Time Elastosonography) and BFI (B-flow imaging) in correlation with the results of the sonographically guided fine-needle(More)
BACKGROUND Increased carotid intima-media thickness (cIMT) is considered a marker of early-onset atherosclerosis and it seems to predict cardiovascular events both in obese and diabetic subjects. We aimed to evaluate early signs of atherosclerosis and investigate for predisposing factors in children and adolescents affected by type 1 diabetes (T1DM) or(More)
Acute appendicitis is the most common cause of acute abdomen requiring emergency surgery. In particular, it affects patients older than 20 years and diagnosis is challenging in this patient subset. The radiologic methods (ultrasound and computed tomography) play a key role in the identification, characterization and staging of the disease as well as optimal(More)
This study prospectively evaluated whole-body magnetic resonance/diffusion-weighted imaging with body signal suppression (WB-MR/DWIBS) reliability compared to 18F-FDG PET/CT in the treatment response assessment of classic Hodgkin lymphomas (HL) and aggressive non-Hodgkin lymphomas (aNHL). Twenty-seven consecutive patients were prospectively enrolled at the(More)
More than two million people tear their anterior cruciate ligament (ACL) each year, and ACL reconstruction occupies a significant proportion of everyday orthopedic practice, being one of the most commonly performed sports medicine surgical procedures. Patients with postoperative symptoms are frequently imaged to monitor ligament grafts and to identify(More)
