The effect of metronidazole was studied in 21 consecutive patients with chronic unremitting perineal Crohn's disease. Drainage, erythema, and induration diminished dramatically in all patients, and complete healing was obtained in 10 of 18 patients maintained on therapy. Five others have shown advanced healing; in 2 patients the inflammation is improved,(More)
Technetium-99m dimethyl acetanilide iminodiacetic acid (HIDA) cholescintigraphy was performed on 90 patients with suspected acute cholecystitis. Visualization of the gallbladder established patency of the cystic duct and excluded the diagnosis of acute cholecystitis in 50 of 52 patients. Nonvisualization of the gallbladder with visualization of the common(More)
Technetium-99m HIDA cholescintigraphy and ultrasonography are noninvasive, safe, simple procedures that can document the presence, location, and extent of a bile leak. Early detection of posttraumatic or postoperative biliary tract disruption can significantly reduce morbidity and mortality. The possibility of biliary tract disruption should be considered(More)
CT performed in patients during suspended full expiration has recently been used to reveal a major physiologic consequence of airway diseases, particularly diseases of those smaller airways beyond the segmental branches: air trapping. Lung regions that retain air during exhalation (air trapping) remain more lucent than normal lung regions do. Detection of(More)
Radiologists must consider several factors when asked by a patient to disclose the results of a radiologic examination. This study represents a survey of radiologists' and clinicians' opinions regarding disclosure of information to patients by the radiologist. A clearer understanding of the preferences of radiologists and clinicians may serve to improve(More)
An increasing number of radiology departments are using computers to facilitate management of radiologic information. Transcription, storage, and printing of radiologic reports are among the primary functions of a radiology information system. Consequently, manual signature of radiologic reports is being replaced by on-line electronic authentication.(More)
OBJECTIVE The purpose of this study was to perform a computer analysis of the size of the thermal injury created by overlapping multiple thermal ablation spheres. MATERIALS AND METHODS A computer-assisted design system was used to create three-dimensional models of a spherical tumor, a spherical tissue volume consisting of the tumor plus a 1-cm tumor-free(More)
The present study of metronidazole in perineal Crohn's disease includes 26 patients, and is composed of 17 of 21 patients who were previously reported and 9 additional consecutive patients. The course of these patients was evaluated to determine if the drug could be reduced or stopped, whether or not it continued to be effective for prolonged periods, and(More)
