An acute whiplash injury follows sudden or excessive hyperextension, hyperflexion, or rotation of the neck and causes neck pain and other symptoms.[1] Whiplash injury is common in road traffic accidents and may also be caused by sports injuries, falls or assaults. Most cases of whiplash injury occur as the result of rear-end vehicle collisions at […]

Magnetic resonance imaging (MRI) of the spine uses radio waves, a magnetic field and a computer to produce detailed pictures of the spine and surrounding tissues that are clearer and more detailed than other imaging methods. The exam does not use ionizing radiation and may require an injection of a contrast material called gadolinium, which […]

Review of MR scans of 11 patients who had been born prematurely revealed findings of periventricular white matter damage, indicative of hypoxic-ischemic brain injury (82%), the chronology of which was difficult to determine. Among 29 patients who had been born at term, three major patterns emerged: (1), gyral anomalies, suggestive of polymicrogyria, consistent with mid-second […]

MRI demonstrates a 2cm rounded lesion in the anterior pole of the left frontal lobe. The lesion is mostly isointense to grey matter, with perhaps small regions of hyperintensity on T1 and T2 weighted images. Of note, there is no well defined central region of T2 hyperintensity. Very extensive vasogenic oedema is present extending back […]

Jason, an undergraduate student at a large state university, is walking back to his apartment after a late night of studying chemistry in the library when he is stopped by the local (non-university) police. They tell him they discovered a deliberately broken window off-campus near the library, and as the only person they found near […]

MRI Carotid Artery and Brain Aneurysm Scan

The word “aneurysm” comes from the Greek word aneurysma (ana, meaning across, and eurys, meaning broad) and denotes an abnormal dilatation of an artery. Cerebral aneurysms involve both the anterior circulation and the posterior, or vertebrobasilar, circulation. Anterior circulation aneurysms arise from the internal carotid artery or any of its branches, whereas posterior circulation aneurysms […]

Susceptibility weighted imaging (SWI) is a new MRI technique that can identify calcification by using phase images. We present a single case with a partially calcified oligodendroglioma, multiple calcified cysticercosis lesions, and multiple physiologic calcifications in the same patient. SWI phase images and computed tomography (CT) images are compared. SWI phase images showed the same […]

Everybody has their own morning routine; for one researcher, this included hopping in to an MRI to scan his brain. For 10 minutes every Tuesday and Thursday over the last year and a half, an MRI took hundreds of pictures. Now, Russell Poldrack has the most studied brain in the world. The images over time […]

MRI c Spine Trauma

All initial evaluations of cervical spine injuries should begin with plain radiographs. A variety of other imaging modalities may also be used, such as conventional tomography, CT, and MRI. An appropriate choice has to be made quickly to make a diagnosis of cervical trauma. When cervical trauma exists, it may be at multiple levels, justifying […]

MRI c Spine Results

While the MRI scan represents a very sensitive and accurate assessment of spinal anatomy, it cannot distinguish between painful and non-painful structures in the spine. In fact, a patient may have severe back pain and an MRI scan that shows a relatively normal-looking spine, or conversely may have no back pain but the MRI scan […]
