OBJECTIVE The purpose of study was to prospectively evaluate the diagnostic performance of dynamic contrast-enhanced MR imaging in the differentiation of malignant lesions from benign ones in patients with BI-RADS 3-4 microcalcifications detected by mammography. MATERIALS AND METHODS 93 women with 100 microcalcifications had undergone breast MRI from June 2010 to July 2013. Subsequently, 91 r...

spontaneous breathing as soon as possible 2 and lowpressure suction of the chest tubes after operation are critical.2, 3 Some ventilatory support is necessary, however, when a patient continues to have hypoventilation after operation. Pressure-controlled ventilation rather than volume-controlled ventilation has been recommended for such patients because it can deliver high inspired gas flows in...

BACKGROUND The aim of the study was to assess the accuracy of imaging techniques in predicting pathologic tumor (ypT), node (ypN) stages and the circumferential resection margin (ypCRM) status of rectal cancers after preoperative chemoradiotherapy (CRT). METHODS Using pelvic computed tomography (CT), magnetic resonance imaging (MRI), and endorectal ultrasound (ERUS), 90 consecutive patients w...

PURPOSE It has been suggested that lipofuscin accumulation, as measured by increased fundus autofluorescence (FAF), precedes progression or development of junctional zone geographic atrophy (GA) in age-related macular degeneration (AMD). The tools of biomedical image analysis were used to measure the probabilistic relationship of GA progression to increased FAF. METHODS Serial AF images of ei...

For one–period projects under certainty, the notion of Net Present Value (NPV) formally translates the notion of economic profit, where the discount rate is the cost of capital. Under uncertainty, the cost of capital is the expected rate of return of an equivalent-risk alternative that the investor might undertake and is often found by making recourse to the Capital Asset Pricing Model. This pa...

The paper discusses the use of a generalized version of the equivalent annuity principle, which takes into account interest rate #uctuations over time. When dealing with applications over a sequence of cycles, e.g. plant replacement ones, the equivalent annuity is usually de"ned with reference to each single cycle or to the whole sequence. First, we study the correspondence between net present ...

BACKGROUND Women with adnexal mass suspected of ovarian malignancy are likely to benefit from consultation with a gynecologic oncologist, but imaging and biomarker tools to ensure this referral show low sensitivity and may miss cancer at critical stages. OBJECTIVE The multivariate index assay (MIA) was designed to improve the detection of ovarian cancer among women undergoing surgery for a pe...

BACKGROUNDS Assessment of predictive values for CA-125, ultrasound features (US) and risk of malignancy index (RMI) in ovarian malignancy. MATERIAL AND METHODS 115 patients, divided into: 1) group-A (n = 41)--ovarian malignancy; group-B (n = 74)--benign ovarian tumor; 2) subgroup-CA(a) with low CA-125 (< 35 U/mL) (n = 64); subgroup-CA(b) with slightly elevated CA-125 (35-130 U/ml) (n = 26); s...
