temporal bone chondroblastoma is an extremely rare benign bone tumor. we encountered two cases showing similar imaging findings on computed tomography (ct), magnetic resonance imaging (mri), and dual-time-point 18f-fluorodeoxyglucose (18f-fdg) positron emission tomography (pet)/ct. in both cases, ct images revealed temporal bone defects and sclerotic changes around the tumor. most parts of the ...

Background and Aims: Magnetic resonance imaging (MRI) plays an essential role in molecular imaging by delivering the contrast agent into targeted cells. The aim of this study was to evaluate the use of magnetic nanoparticles containing iron oxide and silver (Fe3O4@Ag core-shell nanoprobe) as a contrast agent for the detection of ovarian cancer cell line ovcar-3. Materials and Methods: Co-preci...

In recent years, the development of neuroimaging techniques such as high-resolution magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), positron emission tomography (PET), or single photon emission tomography (SPECT) has promoted the identification of structural and functional characteristics underlying mental disorders to a great extent. In anxiety disorders, recent...

abstract background: a tumefactive lesion of central nervous system (cns) is defined as a mass-like lesion with a size greater than 2 cm in brain (magnetic resonance imaging) mri. neuroimaging may help to distinguish the nature of a tumefactive lesion and therefore can prevent an unnecessary brain biopsy. method: in this paper, we have emphasized on determining the nature of a cns tumefactive l...

BACKGROUND This multicentre international randomized trial compared the impact of gadoxetic acid-enhanced magnetic resonance imaging (MRI), MRI with extracellular contrast medium (ECCM-MRI) and contrast-enhanced computed tomography (CE-CT) as a first-line imaging method in patients with suspected colorectal cancer liver metastases (CRCLM). METHODS Between October 2008 and September 2010, pati...

In vivo imaging techniques can be integrated with classical histochemistry to create an actual histochemistry of water. In particular, Magnetic Resonance Imaging (MRI), an imaging technique primarily used as diagnostic tool in clinical/preclinical research, has excellent anatomical resolution, unlimited penetration depth and intrinsic soft tissue contrast. Thanks to the technological developmen...

Abstract Three-dimensional (3D) magnetic resonance imaging (MRI) of the knee is widely used in musculoskeletal (MSK) imaging. Currently, 3D sequences are most commonly for morphological Isotropic MRI provides higher out-of-plane resolution than standard two-dimensional (2D) MRI, leading to reduced partial volume averaging artifacts and allowing multiplanar reconstructions any plane with thickne...

early detection of breast cancer is the most effective way to improve the survival rate in women. magnetic resonance imaging (mri) offers high spatial resolution and good anatomic details, and its lower sensitivity can be improved by using targeted molecular imaging. in this study, as1411 aptamer was conjugated to fe3o4@au nanoparticles for specific targeting of 4t1 cells that overexpress nucle...

Multiparametric magnetic resonance imaging (mp-MRI) has shown promising results in diagnosis, localization, risk stratification and staging of clinically significant prostate cancer, and targeting or guiding prostate biopsy. mp-MRI consists of T2-weighted imaging (T2WI) combined with several functional sequences including diffusion-weighted imaging (DWI), perfusion or dynamic contrast-enhanced ...

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...
