Focal nodular hyperplasia (FNH) is a benign lesion occurring in background of normal liver. FNH seen most commonly young women and can often be accurately diagnosed at imaging, including CT, MRI, or contrast-enhanced US. In the liver, frequently must differentiated from hepatocellular adenoma, which although benign, managed differently because risks hemorrhage malignant transformation. When lesions that are histologically identical to occur abnormal they termed FNH-like lesions. These source...

Our objective was to compare two rapid strip tests for the detection of amniotic fluid, based on insulin-like growth factor-binding protein-1 (IGFBP-1) and placental α-microglobulin-1 (PAMG-1). Samples fluid were taken in 20 pregnant women between 31 3/7 41 2/7 gestational weeks at elective cesarean section before delivery newborn. These samples diluted with 0.9% saline solution a dilution series down concentrations 1:320. Immunoassay then compared their ability detect remaining fluid. In 5...

Background. The objective of this study was to evaluate the predictive value interleukin‐6 (IL‐6) in cervical secretions for preterm delivery before 34+0 gestational weeks patients with labor. Methods. In prospective study, 31 were enrolled labor and intact membranes. Cervical swabs taken on admission concentration IL‐6 measured. age at time delivery, as well interval evaluated compared admission. Results. significantly elevated group (< weeks, p < 0.05). Choosing 20 pg/ml a cut‐off...

514 Background: Promising treatments are emerging for urothelial carcinoma, although there is no reliable method predicting treatment response on an individual basis. Extraction of quantitative tumor-texture features from clinical radiologic images may distinguish between cancers which be more responsive to treatment. Our purpose analyze CT-based textural cancer lymph node metastases prior and classify them categories response. Methods: In this IRB approved retrospective study, 36 patients...

Doppler ultrasound is widely used to identify complications following renal transplantation.Evaluation of arterial waveform involves assessment the peak systolic velocity (PSV), acceleration time or rapidity upstroke, and resistive index (RI).The RI measurement obtained by dividing difference between PSV end diastolic PSV.The resulting ratio eliminates inconsistencies commonly encountered in measuring velocities due inaccurate angle correction can be considered a measure vascular...
