Objective: To investigate the application of background inhibition of fast systemic magnetic resonance diffusion imaging (DWI) in bone metastasis of lung cancer. Methods: Fifty healthy volunteers and 57 patients with lung cancer diagnosed by pathology were examined by WB-DWI, and reconstructed by 3D-MIP and black-and-white flip-flop. The skeletal system was divided into 8 regions, and the numbe...

Intramedullary spinal cord abscess (ISCA) is a rare infection of the central nervous system. We describe the magnetic resonance imaging (MRI) findings, including the diffusion-weighted imaging (DWI) findings, of ISCA in a 78-year-old man. The initial conventional MRI of the thoracic spine demonstrated a subtle enhancing nodule accompanied by significant edema. On the follow-up MRI after seven d...

Background The diffusion weighted imaging (DWI) is a well known technique in neuroradiology, due to its ability to detect ischemic regions in brain tissue. A recent, rapid development of the magnetic resonance technology and echo planar imaging enabled the application of diffusion imaging in cardiac examinations. The aim of this study was to compare the diffusion weighted imaging with widely us...

BACKGROUND AND PURPOSE Fluid-attenuated inversion recovery vascular hyperintensities (FVH) beyond the boundaries of diffusion-weighted imaging (DWI) lesion (FVH-DWI mismatch) have been proposed as an alternative to perfusion-weighted imaging (PWI)-DWI mismatch. We aimed to establish whether FVH-DWI mismatch can identify patients most likely to benefit from recanalization. METHODS FVH-DWI mism...

CONTEXT Acute basilar artery occlusion has particularly high mortality and morbidity. OBJECTIVE To determine the potential utility of advanced magnetic resonance imaging (MRI) methods, including diffusion-weighted imaging, for the early management of patients with basilar artery thrombosis. DESIGN Case series. SETTING Institute of Neuroradiology and Department of Neurology, Johann Wolfgan...

OBJECTIVE To assess the early vascular effects of sunitinib in patients with renal cell carcinoma (RCC) with diffusion-weighted magnetic resonance imaging (DWI), dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) and T2* perfusion MRI. PATIENTS AND METHODS In 10 patients with abdominal RCC lesions, DWI, DCE-MRI and T2* perfusion MRI measurements at 3 Tesla were performed at base...

Background: Metastasis occurs in a significant percentage of patients with renal cell carcinoma (RCC) . Up to 85% of these cancers are clear-cell RCC . Determination of metastases is important to the management of disease, and the imaging techniques play an important role in assessing the metastatic lesions. Whole-body diffusion weighted imaging (DWI) which is able to highlight the oncological ...

The oral cavity constitutes a complex anatomical area that can be affected by many developmental, inflammatory, and tumoural diseases. MultiSlice Computed Tomography (MSCT) Magnetic Resonance Imaging (MRI) currently represent the essential complementary imaging techniques for detecting abnormalities. Advanced MRI with diffusion-weighted (DWI) dynamic contrast-enhanced perfusion-weighted (DCE-PW...
