Anemia and the risk of contrast-induced nephropathy in patients with renal insufficiency undergoing contrast-enhanced MDCT.

Purpose: The purpose of this study was to assess the effect of anemia on the incidence of contrast-induced nephropathy (CIN) in patients with renal impairment undergoing MDCT.

Materials And Methods: Institutional review board approval was waived for this retrospective review of 843 patients with stable renal insufficiency (eGFR between 15 and 60 mL/min) who had undergone contrast-enhanced MDCT. Baseline hematocrit and hemoglobin values were measured.

Detection of breast cancer with a computer-aided detection applied to full-field digital mammography.

A study was conducted to evaluate the sensitivity of computer-aided detection (CAD) with full-field digital mammography in detection of breast cancer, based on mammographic appearance and histopathology. Retrospectively, CAD sensitivity was assessed in total group of 152 cases for subgroups based on breast density, mammographic presentation, lesion size, and results of histopathological examination. The overall sensitivity of CAD was 91 % (139 of 152 cases).

Contrast-induced nephropathy in patients with renal insufficiency undergoing contrast-enhanced MDCT.

Objectives: To evaluate the safety of contrast-enhanced MDCT in patients with renal impairment.

Methods: We conducted a retrospective review of 938 patients with stable renal insufficiency (eGFR between 15 and 60 ml/min) who underwent contrast-enhanced MDCT. SCr levels were measured at baseline and 48-72 h after contrast medium administration.
