PURPOSE We explored appropriate scan timing for bone marrow imaging enhanced using superparamagnetic iron oxide (SPIO) and evaluated the usefulness of SPIO in differentiating metastasis and osteomyelitis in patients. METHODS To determine the adequate scan timing after administration of SPIO, 5 healthy subjects were examined using a 1.5T magnetic resonance (MR) imaging scanner. Sagittal images...

BackgroundThe present review study provides specific evidence to assess the impact of distraction techniques and hypnosis on the pain of bone marrow aspiration in children.Materials and MethodsThis review study aimed to determine the effects of distraction techniques and hypnosis on the controlling pain of bone marrow aspiration in children. Internal databases (SID, Magiran, IranMedex and Irand...

BACKGROUND Ballet dancers have been shown to have a relatively high incidence of stress fractures of the foot and ankle. It was our objective to examine MR imaging patterns of bone marrow edema (BME) in the ankles of high performance professional ballet dancers, to evaluate clinical relevance. METHODS MR Imaging was performed on 12 ankles of 11 active professional ballet dancers (6 female, 5 ...

Abstract Imaging plays a vital role in the diagnosis and management of rheumatological disorders. While plain film radiography was traditionally primary investigative tool for arthropathies, bony changes seen on radiographs often occur late disease process. Therefore, imaging modalities that allow us to visualize earlier changes, such as synovitis, bone marrow oedema erosions, are favo...

Objective(s):To study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. Materials and Methods:Forty New Zealand rabbits were randomly divided into five groups with eight rabbits in each group. For each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. To t...

thisis a case report of a 24-year-old man who presented with increased pain and firm swelling of the right foot after a minor twisting injury. radiography, computed tomography (ct) and magnetic resonance imaging (mri) findings showed ancillary information that was helpful for surgical treatment. the final diagnosis was confirmed aschondroblastoma of the navicular bone based on the pathology rep...

Detection of bone involvement is essential for optimal therapy of oncologic patients. The purpose of imaging is to identify early bone involvement, to determine the full extent of the skeletal disease, to assess the presence of accompanying complications-such as fractures and cord compression-and to monitor response to therapy. Detection of bone involvement by various imaging modalities is base...

In diffusion-weighted magnetic resonance imaging (DWI-MRI), the observed MRI signal intensity is attenuated by the self-diffusion of water molecules. DWI can provide information about the microscopic structure and organization of biological tissue and thus can depict various pathological changes of organs or tissues. DWI has been successfully used for the characterization of bone marrow alterat...

Introduction: Apoptosis is a major consequence of ionizing radiation in proliferative tissues and quantification of the apoptotic cells could be helpful for noninvasive assessment and estimation of the radiation absorbed dose. Annexin V conjugated with super paramagnetic iron oxide nanoparticles (ANX-SPIO) is a biological probe for detection of apoptotic cells using magnetic resonance imaging. ...

Ankylosing spondylitis (AS) is a chronic inflammatory disease which affects primarily the sacroiliac joints and the spine. In patients with active disease, magnetic resonance imaging (MRI) of the spine shows areas of bone marrow edema, the histopathological equivalent of which is unknown. In this study we correlate inflammation in the spine of patients with AS as revealed by histological examin...
