Non-enhancing malignant lesions of the breast: A case report and review of literature.

Due to the elusive nature of invasive lobular carcinoma, mammography, ultrasound, and magnetic resonance imaging have their limitations in early detection. A 67-year-old woman presented for mammography and found retraction of breast parenchyma of the right breast. Magnetic resonance imaging and contrast mammography showed no contrast uptake in the region in question.

Side-by-side evaluation of virtual non-contrast and post-contrast images improves detection of clinically significant urolithiasis on single-phase split bolus dual-energy CT urography.

Objectives: Studies show insufficient sensitivity of virtual non-contrast (VNC) reconstructions for stone detection in dual-energy CT urography (DE-CTU). The aim of this study was to investigate if side-by-side-evaluation of both VNC and post-contrast images could increase the sensitivity of single-phase split bolus DE-CTU.

Methods: Consecutive patients with haematuria who underwent split bolus DE-CTU on the same dual-source DE-CT scanner were retrospectively enrolled in the study.

Does Cytological Laboratory Holds the Responsibility for the Low Sensitivity of the PAP Test in Detecting Endometrial Cancer?

Endometrial cancer is the most common gynecological cancer but there is no economically justified screening method. Although we can detect endometrial cells in the sample using PAP test, many studies show low sensitivity and positive predictive value of PAP test for the diagnosis of endometrial cancer. The goal of this research was to determine significance of PAP test for the diagnostics of endometrial carcinoma.
