2) patient with surgical hardware in spine which obscures visualization of spinal canal on mri and ct scan indication for ct myelogram injection of contrast material into thecal sac under flouroscopic guidance with subsequent ct imaging of the spine.
Moreover, spinal ct is capable of visualising the brachial plexus using multiplanar constructions, although its lacking detail and contrast render it largely ineffective compared to mri (van es, 2001.
A request arrives from general practitioner (gp) which reads “lumbar spine mri” clinical indications: 50 year old male complaining of back pain and fever you performed a t2 sagittal on l1-s1. Suggest an mri protocol for a patient presenting with thoracic outlet syndrome should provide full discussion /justification of sequence inclusion mri sequence types and parameters are explained and supported section 2: a request arrives from general practitioner (gp) which reads “lumbar spine mri.
A spinal cord injury can prompt a physician to order an mri instead of a ct scan (“magnetic resonance imaging”) for instance, multiple sclerosis plaques within the spinal cord do not show up well in ct scans, but are dazzlingly clear in an mri (marieb 9. - magnetic resonance imaging mri is a procedure, in wide use since the 80s, to see the anatomy of the internal organs of the body it is based on the phenomenon of nuclear magnetic resonance (nmr), first described in landmark papers over fifty years ago (rabi et al 1938 rabi, millman, and kusch 1939 purcell et al 1945 bloch, hansen, and packard 1946) (4 ).
Beyond doubt mri is the choice of modality in imaging spine and brain as, due to very high contrast resolution, mri provides excellent white and grey matter differentiation this has made complicated operations of the brain and spine simpler. The different stages of sacroiliac involvement on ct and mri are similar to those observed in the spine [2, 13] the early inflammatory changes of the joint are best detected with mri, although erosions, sclerotic changes, and ankylosis are also well depicted using ct [ 4 , 6 , 7 , 13 .
