Magnetic resonance imaging (MRI) has provided an unparalleled window into understanding multiple sclerosis (MS). Through recognition of relatively specific characteristics of MS, MRI has become an integral part of patient initial evaluation and long-term management. MRI has now been integrated into the formal diagnostic criteria, whereby new lesions can fulfill either dissemination in space or ...

Transrectal ultrasonography (US)-guided biopsy is the standard approach for histopathologic diagnosis of prostate cancer. However, this technique has multiple limitations owing to the operator's inability in most cases to directly visualize and target prostate lesions. Magnetic resonance (MR) imaging of the prostate overcomes many of these limitations by directly depicting areas of abnormality ...

Conventional mammographic image contrast is derived from x-ray absorption, resulting in breast structure visualization due to density gradients that attenuate radiation without distinction between transmitted, scattered, or refracted x-rays. Diffractionenhanced imaging (DEI) allows for increased contrast with decreased radiation dose compared to conventional mammographic imaging due to monochro...

Neutron imaging finds applications in many branches of science and industry such as in nondestructive testing, material science etc. Conventional imaging of neutrons has been carried out mostly using analogue technology such as screen film imaging. Making transition from analogue to digital could bring several advantages such as fast image acquisition and display, implementation of image proces...

Intracranial chondrosarcomas have a predilection for the skull base, for which CT and MR imaging findings have been described. We present a rare case of primary chondrosarcoma arising from the falx in a young woman with no history of radiation. The CT, conventional MR imaging, perfusion MR imaging, and digital subtraction angiography findings are described.

BACKGROUND Imaging of musculoskeletal tumors requires a multimodality approach and includes radiography, computed tomography (CT), and magnetic resonance imaging (MRI). METHODS Topics related to primary bone and soft-tissue tumors are reviewed. The fundamental imaging principles are discussed as well as the applications of emerging imaging modalities. RESULTS MRI is the preferred technique ...

STUDY DESIGN Soft tissue-related injuries to the cervical spine structures were produced by use of intact entire human cadavers undergoing rear-end impacts. Radiography, computed tomography, and cryomicrotomy techniques were used to evaluate the injury. OBJECTIVES To replicate soft tissue injuries resulting from single input of whiplash acceleration to whole human cadavers simulating vehicula...
