Accuracy of sonographically guided biopsy using a freehand versus needle-guided technique: computed tomographic correlation study.

Sonographically guided biopsy is performed by one of two techniques: the freehand and needle-guided techniques. To our knowledge, the relationship between the location of the local anesthetic tract and the biopsy needle tract as well as direct comparison of the two biopsy techniques has not been previously validated. The aim of this study was to validate the different parameters related to the two biopsy techniques using computed tomography as the reference standard for assessing final tract positions.

Sonographic and magnetic resonance imaging findings in uterine incarceration.

We show the sonographic and magnetic resonance imaging features of uterine incarceration. Clinical data and imaging findings were retrospectively reviewed for 8 confirmed cases identified by sonography from 2000 to 2010. Two patients had magnetic resonance imaging.

Gallbladder needle decompression during radiofrequency ablation of an adjacent liver tumour.

Gallbladder perforation with bile leak can result from thermal injury during radiofrequency ablation of liver tumours. Two case studies demonstrate a technique for preventing gallbladder injury to the peritoneal surface of a distended gallbladder adjacent to the anticipated hepatic ablation zone. The use of percutaneous gallbladder needle decompression can safely separate or retract the peritoneal surface of the gallbladder from a contiguous hepatic radiofrequency ablation zone.

Cross-sectional imaging of small bowel malignancies.

Small bowel malignancies are rare neoplasms, usually inaccessible to conventional endoscopy but detectable in many cases by cross-sectional imaging. Modern multidetector computed tomographies permit accurate diagnosis, complete pretreatment staging, and follow-up of these lesions. In this review, we describe the cross-sectional imaging features of the most frequent histologic subtypes of the small bowel malignancies.

Patient profiles at a centralized, urban, diabetes education centre.

Background: Little is known about the characteristics of patients attending diabetes education centres (DECs). To address this knowledge gap, we examined the clinical characteristics of patients referred to a centralized urban DEC.

Methods: Using a clinically detailed patient registry, we studied the profiles of 1459 patients seen in an urban DEC, and compared patients referred to the DEC by family physicians (FPs) to those referred by other physicians (usually specialists), and patients referred to the DEC for the first time to those who had been referred a number of times (multiply-referred patients).
