To assess the spectrum of complications after emergency tube thoracostomy (TT) and show the role of computed tomography (CT) in detection of these abnormalities. ⋯ Patients undergoing emergency TT are at increased risk for complications. CTM is the most common abnormality and should be diagnosed promptly to prevent additional problems. CT is more useful than plain radiography for establishing a diagnosis.

Randomized Controlled Trial Comparative Study Clinical Trial
MR imaging field strength: prospective evaluation of the diagnostic accuracy of MR for diagnosis of multiple sclerosis at 0.5 and 1.5 T.
To compare the diagnostic efficacy of middle-field-strength and high-field-strength magnetic resonance (MR) imaging in diagnosis of multiple sclerosis. ⋯ Higher field strength does not confer higher accuracy in the diagnosis of multiple sclerosis with current-generation MR imagers.
-
To determine the frequency of posterior ligamentous injury that occurs in patients with thoracolumbar burst fractures and to correlate ligamentous disruption with radiographic appearance. ⋯ SSL disruption is a frequent occurrence in patients with burst fractures. No radiographic features of burst fractures correlate with SSL disruption, and radiographic signs of posterior ligamentous disruption are insensitive.

To evaluate whether magnetization transfer (MT) can improve image contrast on gradient-recalled echo (GRE) magnetic resonance (MR) images of the cervical spine. ⋯ The MT GRE images demonstrated superior delineation of disk herniations, foraminal stenosis, and intrinsic cord lesions over conventional GRE and T2-weighted spin-echo images in clinical cervical spine examinations.
