Performance of CT in detection of bowel injury.

Objective: The objective of our study was to identify relevant and reliable CT signs of bowel injury, to determine the overall performance of CT in detection of bowel injuries, and to establish the effect of the training level of radiologists on this performance.

Materials And Methods: Abdominal CT scans of 112 patients with blunt abdominal trauma were prospectively and retrospectively reviewed. Fifty patients had proven bowel injuries (with or without other visceral injuries), whereas 62 patients had no bowel injury and comprised the comparison or control group.

Normal anatomy of the neck with CT and MR imaging correlation.

Knowledge of normal anatomy is the cornerstone for understanding pathologic processes. Often, the most difficult task for a radiologist is differentiating normal structures from pathology. There are many ways to organize a discussion of the normal anatomy in the neck.

The CT appearance of thyroglossal duct carcinoma.

Background And Purpose: Thyroid carcinoma arising in a thyroglossal duct cyst may be clinically indistinguishable from a benign thyroglossal duct cyst. The preoperative diagnosis of carcinoma, however, can have important implications for surgical planning and postoperative treatment. Our purpose was to describe the CT appearance of thyroglossal duct carcinoma and identify the features that distinguish thyroglossal duct carcinoma from benign thyroglossal duct cysts.

Imaging of a Stafne bone cavity: what MR adds and why a new name is needed.

Stafne bone cavities are asymptomatic radiolucencies seen at the angle of the mandible. Although plain films are often sufficient for diagnosis, confirmatory imaging is needed in atypical cases. We describe the MR imaging findings of a Stafne bone cavity, describe the contents, explain why a new name is needed, and discuss the relative merits of different radiologic techniques for establishing this diagnosis.

[A comparative multicenter study of the efficacy of single- and double-lumen catheter drainage].

Our study was aimed at comparing the therapeutic efficiency of single and double lumen catheters in the drainage of abdominal fluid collections. We report the results of in vitro and in vivo studies carried out to assess the usefulness of each catheter type based on its therapeutic results. In the in vitro study the aspiration efficacy of the catheters was tested in a simulated cavity.

Chloroquine-sensitive transplasmalemma electron transport in Tetrahymena pyriformis: a hypothesis for control of parasite protozoa through transmembrane redox.

Plasma membrane electron transport was studied in a protozoan cell, Tetrahymena pyriformis, by assaying transmembrane ferricyanide reduction and the reduction of iron compounds. The rates of ferricyanide reduction varied between 0.5 and 2.

Molecular characterization of sylvatic isolates of Trichinella spiralis.

Genetic relationships of 20 Trichinella isolates from Indiana wildlife were assessed and compared to Trichinella isolated from an infected swine herd. Trichinella larvae were isolated from coyotes, mink, raccoons, and red foxes. The larvae were maintained and amplified in white mice (ICR) and wild mice (Peromyscus leucopus).
