Neurolymphomatosis is a rare manifestation of non-Hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. This report presents positron emission tomography/computed tomography (PET/CT)imaging with 2-deoxy-2-18F-fluoro-D-glucose (18F-FDG) in 3 cases of non-Hodgkin lymphoma with nerve infiltration, including one newly d...

The purpose of this study was to investigate magnetic resonance imaging (MRI) of the normal feline eyeand optic nerves using T1-weighted and T2-weighted images. A total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. Magnetic resonance imaging data werecollected using GEMSOW (Philips) at a magnetic field strength of 1.5 T. Dorsal, sagittal, a...

inflammatory myofibroblastic tumor (imt) is an aggressive benign mass that may arise from various tissues and organs with a great variability of histological and clinical appearances. due to variable and nonspecific imaging findings, diagnosis of imt is not obtained before surgery. the aim of this paper is to present ct and mri findings during four-year follow-up of complete, spontaneous regres...

the incidence of multiple myeloma (mm) affecting the jaws is 30% and on rare occasions the oral involvement can be the first indication of the disease. authors report a case of mm in a 40-yearold woman who presented with a multilocular radiolucent lesion in the left mandible initially mistaken as an ameloblastoma. conventional radiographs revealed a multilocular lesion on the molar region. comp...

Introduction: According to the literature, optical coherence tomography (OCT) can be used measure radiation absorbed dose. This study was carried out to design a computed tomography system for the calculation of absorbed dose and optimization of dose delivery in radiotherapy using gel dosimeters. Material and Methods: An advanced charge-coupled device based OCT system was developed in laborator...

objectives the aim of this study was to evaluate the value of diffusion weighted imaging in diffusion weighted imaging in distinguishing between in benign and malignant breast lesion methods there were 37 female patients with 47 lesions. sixty seven female subjectd (40 mean age ) ,age ranges 17-69 , with histopathologically proven breast lesions underwent dwi of breasts with a single shot echo ...

Objective(s): Contrast-enhanced magnetic resonance imaging (MRI) of breast cancer provides valuable data on the disease state of patients. Biocompatible nanoprobes are expected to play a pivotal role in medical diagnosis in the future owing to their prominent advantages. The present study aimed to introduce a novel biocompatible nanoprobe based on lipoproteins for breast cancer cell imaging.<br...
