COMPARISON OF CAROTID STENOSIS GRADING BY CT ANGIOGRAPHY AND DOPPLER ULTRASONOGRAPHY: HOW THE STATISTICAL METHODS APPLIED INFLUENCE THE RESULTS.

In this study, we compared the measurement of carotid stenosis by computed tomography angiography (CTA) based on the narrowest diameter cross sectional area (CSA) with the measurement by color Doppler ultrasonography (CDUS) as a reference standard, and analyzed how the application of different statistical methods affected the result. On 113 carotid arteries with ≥50% stenosis, we quantified the level of correlation among the three measurements, sensitivity, specificity, and differences in the estimated stenosis level. Correlation between both CTA measurements was good with Pearson's ρ between 0.

Association of the imaging characteristics of desmoplasia on digital breast tomosynthesis and the Ki-67 proliferation index in invasive breast cancer.

Aim: To evaluate the imaging characteristics of desmoplasia on digital breast tomosynthesis (DBT) and their association with the Ki-67 index.

Methods: Seventy-seven malignant spiculated breast masses were analyzed in terms of tumor size, length and width of spicules, coverage of tumor margin with spicules, and the number of spicules. The Ki-67 index was obtained from surgically removed tumor specimens.

Grading of carotid artery stenosis with computed tomography angiography: whether to use the narrowest diameter or the cross-sectional area.

Objectives: To compare the estimation of carotid artery stenosis by computed tomography angiography (CTA) based on cross-sectional area versus the smallest diameter measurement, and test the accuracy of both CTA measurements using color Doppler ultrasonography (CDUS) as a reference method.

Methods: For 113 carotid arteries with stenosis ≥50% we analysed the differences in the estimated stenosis level between both CTA methods and CDUS using the Bland-Altman approach. Further, we calculated sensitivity, specificity and plotted receiver operating characteristic (ROC) curves for both CTA methods.

Hernia of Morgagni--case report.

Morgagni's hernia is result of penetration of the abdominal contents into the chest through an anterior retrocostoxiphoid defect in the anterior midline of the diaphragm. It can be manifested with symptoms since birth as a bloated feeling, nausea and belching after meals. We present a patient with symptomatic herniation of the torqued antral part of stomach and loops of the transverse colon.

Mangled extremity--case report, literature review and borderline cases guidelines proposal.

Treatment of a mangled lower extremity represents a major challenge. The decision whether to amputate or attempt reconstruction is currently based upon surgical evaluation. The aim of this paper is to propose a new approach to surgical evaluation based on scoring systems, local clinical status of the patient as well as comorbidities, mechanism of trauma and hospital resources.
