Characterizing the compression-dependent viscoelastic properties of human hepatic pathologies using dynamic compression testing.

Recent advances in elastography have provided several imaging modalities capable of quantifying the elasticity of tissue, an intrinsic tissue property. This information is useful for determining tumour margins and may also be useful for diagnosing specific tumour types. In this study, we used dynamic compression testing to quantify the viscoelastic properties of 16 human hepatic primary and secondary malignancies and their corresponding background tissue obtained following surgical resection.

MRI of pregnancy-related issues: müllerian duct anomalies.

Objective: Müllerian duct anomalies can adversely affect pregnancy outcomes and can result in clinical symptoms. This article will review the appropriate management of patients with müllerian duct abnormalities.

Conclusion: Whereas uterine and vaginal septa, vaginal agenesis, and unicornuate uterus can be managed surgically, other uterine anomalies tend to be managed clinically.

Incidental adnexal masses detected at low-dose unenhanced CT in asymptomatic women age 50 and older: implications for clinical management and ovarian cancer screening.

Purpose: To determine the prevalence, work-up, and outcomes of indeterminate adnexal masses identified at low-dose unenhanced computed tomography (CT) in asymptomatic women age 50 and older undergoing colonography screening.

Materials And Methods: This study was institutional review board approved and HIPAA compliant. Informed consent was waived.

Colorectal and extracolonic cancers detected at screening CT colonography in 10,286 asymptomatic adults.

Purpose: To retrospectively determine the detection rates, clinical stages, and short-term patient survival for all unsuspected cancers identified at screening computed tomographic (CT) colonography, including both colorectal carcinoma (CRC) and extracolonic malignancies.

Materials And Methods: From April 2004 through March 2008, prospective colorectal and extracolonic interpretation was performed in 10,286 outpatient adults (5388 men, 4898 women; mean age, 59.8 years) undergoing screening CT colonography at two centers in this institutional review board-approved, HIPAA-compliant study.

CT colonography: performance and program outcome measures in an older screening population.

Purpose: To evaluate computed tomographic (CT) colonography performance and program outcome measures in an older cohort (65-79 years) of an established large-scale colorectal cancer screening program.

Materials And Methods: This HIPAA-compliant study was approved by the institutional review board; informed consent waived. Retrospective analysis of the 65-79-year-old cohort (n = 577) from the University of Wisconsin CT colonography screening program (n = 5176) was undertaken.

Unsuspected extracolonic findings at screening CT colonography: clinical and economic impact.

Purpose: To evaluate the frequency and estimated costs of additional diagnostic workup for extracolonic findings detected at computed tomographic (CT) colonography in a large screening cohort.

Materials And Methods: This retrospective HIPAA-compliant study, which had institutional review board approval, evaluated extracolonic findings in 2195 consecutive asymptomatic adults (1199 women, 996 men; age range, 40-90 years; mean age, 58.0 years +/- 8.

Anatomic factors predictive of incomplete colonoscopy based on findings at CT colonography.

Objective: Reasons for failure to reach the cecum at optical colonoscopy are multifactorial. The purpose of this study was to compare CT colonography (CTC) findings in patients with complete versus those with incomplete optical colonoscopy.

Materials And Methods: The clinical data and CTC examinations were reviewed in 100 patients who underwent CTC after incomplete optical colonoscopy.
