0.2 mL/kg in adults, children and infants.Your doctor has suggested you have an MRI as part of the evaluation at National Jewish Health. The recommended dose of gadolinium DTPA injection is 0.1 mmol/kg, i.e. Use T1 TSE Fat saturated axial and sagittal after the administration of IV gadolinium DTPA injection(copy the planning outlined above). > MS, hemipeligia/paresthesia and Infection Indications for contrast enhancement spine scans This is to avoid the peristalsis and breathing artefacts over the spinal area. A saturation band must be placed over the abdomen (in front of the aorta) in the sagittal plane. Slices must be sufficient to cover the intervertebral discs (normally 5 slices for each disc space). An appropriate angle must be given in the coronal plane on a tilted or scoliotic spine (Parallel to the intervertebral disc space). Additional blocks must be taken in the presence of prolapsed disc in any other levels. Plan the axial slices on the sagittal plane angle the first position block parallel to L5- S1 intervertebral disc, second position block parallel to L4- L5 intervertebral disc, third position block parallel to 元- L4 intervertebral disc and fourth position block parallel to L2- 元 intervertebral disc (only four blocks are needed in a normal spine). Phase direction should be head to feet to avoid further motion artefacts form abdomen. Slices must be sufficient to cover the spine from the lateral border of RT transverse process up to the lateral border of LT transverse process. Check the position block in the sagittal plan FOV must be big enough to cover the whole lumbar and sacral spine from T11 down to coccyx (normally 350mm). An appropriate angle must be given in the axial plane on a tilted patient (Parallel to the line along the centre of the vertebral body and the spinous process). Check the positioning block in the other two planes. Plan the sagittal slices on the coronal plane angle the position block parallel to spinal cord. Suggested protocols, parameters and planningĪ three plane localiser must be taken in the beginning to localise and plan the sequences. Give cushions under the legs for extra comfortĬentre the laser beam localiser over the mid abdomen (4 inches above the iliac crest) Position the paient in the spine coil and immobilise with cushions Offer earplugs or headphones, possibly with music for extra comfort If possible, provide a chaperone for claustrophobic patients (e.g. Gadolinium should only be given to the patient if GFR is > 30 Pregnancy (risk vs benefit ratio to be assessed)Ī satisfactory written consent form must be taken from the patient before entering the scanner roomĪsk the patient to remove all metal object including keys, coins, wallet, any cards with magnetic strips, jewellery, hearing aid and hairpinsĪsk the patient to undress and change into a hospital gownĬontrast injection risk and benefits must be explained to the patient before the scan Intracranial aneurysm clips (unless made of titanium) cardiac pacemaker, insulin pump biostimulator, neurostimulator, cochlear implant, and hearing aids) Please check our new video tutorial for protocols and planningĪny electrically, magnetically or mechanically activated implant (e.g. > Non-traumatic vascular injuries of the spine > Evaluation or monitoring of demyelinating disease > Evaluation or monitoring of spinal cord compression > Investigation of any cause of spinal disease in pregnancy > Evaluation or monitoring of tumour of the CNS or meninges > Evaluation or monitoring of inflammation of the CNS or meninges > Evaluation or monitoring of congenital malformations of the spinal cord > Possible spinal cord injury and post-traumatic neurologic deficit > Myelopathies, Multiple Sclerosis and other demyelinating diseases > Infectious or inflammatory processes (eg.spinal cord Abscess or spinal osteomyelitis) Localized back pain and radiculopathy with 6-week course of conservative care and inadequate
