A thermographic technique is described that uses cholesteric liquid crystals that change color in response to variations in surface temperature. The crystals are embedded in elastic flexible sheets that conform to the contours of the torso and extremities. The technique is well suited to temperature measurement of individual skin dermatomes and myotomes. Typical heat patterns emanating from the...

One hundred patients were questioned after metrizamide myelography about the side effects of the examination. The number and type of side effects were tabulated and correlated with investigated region (e.g., cervical, lumbar) and with use of medication (e.g., analgesics, diuretics). The number of side effects, particularly neuropsychologic, were higher than previously reported. The most common ...

MR imaging with surface coils is currently the preferred method for the evaluation of cervical soft disc herniation. However, the differentiation between soft disc herniation and osteophytic spurs in the neural foraminal canal is not always obvious on a 0.5 Tesla unit. Therefore the specificity for neural foraminal canal pathology has been reported not to be very high. We evaluated MRI in selec...

ObjectiveTo evaluate and compare the radiographic efficacy and safety of a non-ionic dimeric and isotonic iodinated contrast medium, iodixanol (320 mgI/ml) and a non-ionic monomer and hypertonic contrast medium, iohexol (300 mgI/ml) in feline cervical myelography. DesignExperimental study AnimalsFive adult healthy cats. ProceduresIodixanol and iohexol were injected into the cerebellomedullary c...

Thorough myelography of the entire spinal cord including the foramen magnum region can be accomplished consistently and promptly after metrizamide injection via lumbar or lateral cervical puncture. When lumbar puncture is used the patient's torso is oblique, but the neck is prone and straight and the table is tilted 20 degrees head-down to allow direct cervical filling with contrast material. E...

STUDY DESIGN A prospective clinical study. OBJECTIVE To investigate the dynamic causative factor in the pathogenesis of myelopathy in patients with cervical ossification of the posterior longitudinal ligament (OPLL) using kinematic computed tomography (CT) myelography. SUMMARY OF BACKGROUND DATA Kinematic CT myelography is useful for dynamically evaluating the cervical spine with high-resol...

A 42 year old Greek male with pseudo-pseudohypoparathyroidism presented with difficulty in walking and with lower limb weakness. His physical signs included short stature, thick neck, short fourth metacarpals and metatarsals, and a spastic paraparesis. Serum calcium and phosphate and parathyroid concentrations were normal. Myelography demonstrated compression of the cervical and lumbar cord in ...
