Background: Glucose transporter (Glut), a cellular transmembrane receptor, has a key role in the metabolism of cell glucose and is also associated with various human carcinomas.Objective: In this study, we evaluated a magnetic resonance (MR) imaging contrast agent for tumor detection based on paramagnetic gadolinium oxide (Gd2O3) coated polycyclodextrin (PCD) and mod...

Magnetic resonance imaging is increasingly being used to evaluate the lymphatic system. Advances in magnetic resonance (MR) software and hardware allow improved visualization of lymph nodes and lymphatic vessels. We describe how MR lymphangiography can be used to diagnose central lymphatic system anatomy and pathology, which can be used for diagnostic purposes or for pre-procedural planning.

The magnetic resonance (MR) findings are presented of a nonfunctioning mediastinal paraganglioma on both T1- and T2-weighted magnetic resonance images. The MR characteristics of this tumor differentiate it from previously reported functioning mediastinal paragangliomas (pheochromocytoma) and from other benign mediastinal neoplasms, although mediastinal bronchogenic carcinoma may produce a simil...

BACKGROUND Magnetic resonance (MR) imaging of the neonate has been restricted by the need to transport the sick baby to the large magnetic resonance scanners and often the need for sedation or anaesthesia in order to obtain good quality images. Ultrasound is the reference standard for neonatal imaging. OBJECTIVE To establish a dedicated neonatal MR system and compare the clinical usefulness o...

Introduction: Nowadays, magnetic resonance imaging (MRI) in combination with computed-tomography (CT) is increasingly being used in radiation therapy planning. MR and CT images are applied to determine the target volume and calculate dose distribution, respectively. Since the use of these two imaging modalities causes registration uncertainty and increases department w...

background : magnetic resonance imaging of the breast is becoming a useful adjunct to mammography and sonography for the detection of breast lesions. however, it is not yet accepted as a routine examination for all breast cancer patients due to the lack of data regarding whether breast magnetic resonance imaging impacts recurrence or survival. this trial examines the use of magnetic resonance i...
