Conventional vs Computed Radiography : Evaluation of Myelography 165
Digital imaging is becoming widely used in diagnostic radiology, and digital subtraction angiography (DSA) is now generally accepted [1-3]. Several studies have evaluated digital imaging using a computed radiography system for chest examinations [4-10] and for excretory urography [11] . This prospective study uses receiver operating curve analysis [12 , 13] to compare the diagnostic accuracy of...
متن کاملThe diagnostic value of CT myelography, MR myelography, and both in neonatal brachial plexus palsy.
BACKGROUND AND PURPOSE Although most infants with brachial plexus palsy recover function spontaneously, approximately 10-30% benefit from surgical treatment. Pre-operative screening for nerve root avulsions is helpful in planning reconstruction. Our aim was to compare the diagnostic value of CT myelography, MR myelography, and both against a surgical criterion standard for detection of complete...
متن کاملDetection of cerebrospinal fluid metastasis: CT myelography or MR?
PURPOSE To determine the sensitivity of contrast MR versus myelography followed by CT in the detection of cerebrospinal fluid metastases in children with primary central nervous system tumors. METHODS Thirty-three patients who had primary central nervous system malignancies had spinal MR with gadolinium within 2 weeks of a myelogram followed by CT. MR technique included T1-weighted image sequ...
متن کاملLumbar root compression in the lateral recess: MR imaging, conventional myelography, and CT myelography comparison with surgical confirmation.
BACKGROUND AND PURPOSE Previous authors have shown that conventional myelography is superior to plain CT in the assessment of root compression in the lateral recess, but this question has never been evaluated with respect to MR imaging of the lumbar level. Our purpose was to assess the accuracy of MR imaging, conventional myelography, and postmyelography CT (CT myelography) of the lumbar level ...
متن کاملThree-dimensional MR myelography of traumatic injuries of the brachial plexus.
PURPOSE To determine the diagnostic accuracy of three-dimensional MR myelography in the evaluation of traumatic injuries of the brachial plexus. METHODS Twenty patients with clinical and electromyographic evidence of traumatic brachial plexopathy were examined with three-dimensional MR myelography, conventional cervical myelography, and CT myelography 1 to 9 months after trauma. Three-dimensi...
