BACKGROUND AND PURPOSE: In theory, ionic solutes diffuse more slowly in cartilage
than do nonionic solutes. We tested the hypothesis that the contrast ratio between scar and …

nonionic ones. The purpose of this study was to test the hypothesis that the contrast between …

PURPOSE To compare the MR contrast enhancement produced by ionic and nonionic
paramagnetic contrast media in herniated disk fragments with that in epidural scar tissue …

PURPOSE To study the utility of high-dose contrast enhancement in the detection of
recurrent herniated disk fragments. METHODS Recurrent herniated disks were modeled in …

PURPOSE Our goal was to compare contrast enhancement of recurrent herniated disk
fragments and scar after intravenous injection of a new high-molecular-weight contrast …

Study Design. A comparison of contrast enhancement in the intervertebral disc from two
magnetic resonance imaging contrast media in experimental animals. Objectives. To test the …

Study Design: This study is an experimental investigation on the gadolinium contrast
magnetic resonance imaging (MRI) in distinguising sequestered disc fragment versus scar …

PURPOSE To measure the effect of contrast medium dose, time elapsed since injection, and
maturity of epidural scar tissue on the enhancement of scar tissue in MR imaging …

BACKGROUND AND PURPOSE Experimental studies have shown that solutes diffuse more
slowly into degenerated intervertebral disks than into normal disks. A noninvasive clinical …

Magnetic resonance imaging (MRI) has become a principal modality in the evaluation of the
postoperative lumbar spine. Gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA) can …
