Comparative StudyDetection and segmental location of malignant hepatic tumors: comparison of ferumoxides-enhanced gradient-echo and T2-weighted spin-echo MR imaging.
The aim of our prospective study was to compare the values of ferumoxides-enhanced gradient-echo and T2-weighted spin-echo MR imaging for the detection and segmental location of malignant hepatic tumors. ⋯ In our study, ferumoxides-enhanced gradient-echo imaging was as accurate as T2-weighted spin-echo imaging for revealing malignant hepatic tumors and was superior for showing their segmental location.

Endometrial thickness in tamoxifen-treated patients: correlation with clinical and pathologic findings.
This study was performed to evaluate sonographic measurements of endometrial thickness in postmenopausal breast cancer patients being treated with tamoxifen and to correlate endometrial thickness with pathology, symptoms, and duration of tamoxifen treatment. ⋯ The majority of women being treated with tamoxifen were asymptomatic, but 48% of sonograms revealed an endometrial thickness of 8 mm or more. Endometrial polyps, the most common abnormality, were diagnosed in 33% of biopsies performed for endometrial thickness of 8 mm or more. Endometrial thickness showed no correlation with symptoms, but we found a statistically significant correlation between increased endometrial thickness and duration of tamoxifen treatment that was longer than 5 years.

CT findings of mesenteric injury after blunt trauma: implications for surgical intervention.
The purposes of this study were to determine the spectrum of CT findings of mesenteric injury, to compare CT findings of mesenteric injury with surgical observations, and to assess the potential of CT to predict which patients with mesenteric injury require laparotomy. ⋯ The CT finding of mesenteric bleeding or bowel wall thickening associated with mesenteric hematoma or infiltration in the blunt trauma patient indicates a high likelihood of a mesenteric or bowel injury requiring surgery. The finding of focal mesenteric hematoma or infiltration without adjacent bowel wall thickening is nonspecific and can occur both in mesenteric or bowel lesions that require surgery and those that do not.

Comparative StudyHepatic cavernous hemangioma: appearance on T2-weighted fast spin-echo MR imaging with and without fat suppression.
The goals of our study were to define the morphologic appearance of cavernous hemangioma of the liver on T2-weighted fast spin-echo MR imaging and to determine if the use of fat suppression may quantitatively and qualitatively modify the MR imaging appearance of cavernous hemangioma. ⋯ Seventy-six percent of hepatic cavernous hemangiomas were homogeneous on T2-weighted fast spin-echo MR imaging, and 55% were isointense to CSF. However, only 34% of hepatic cavernous hemangiomas showed typical features. Although fat suppression significantly increased the C/N ratio of cavernous hemangiomas of the liver, fat suppression did not affect their morphologic appearance on T2-weighted fast spin-echo MR imaging.

Esophageal foreign bodies: safety and efficacy of Foley catheter extraction of coins.
Continued controversy over the role of fluoroscopically guided Foley catheter removal of esophageal foreign bodies has limited the use of this technique despite its significant economic advantages. We reviewed our experience for the safety, efficacy, and applicability of this technique with pediatric patients who had swallowed coins. ⋯ Fluoroscopically guided Foley catheter extraction of retained coins in pediatric patients who lack evidence of significant esophageal edema causing tracheal compromise is a safe and efficacious technique. It should be considered the technique of choice for such extractions.
