    Abstract : Abstract Background: Short cervical length is a risk factor for preterm delivery (PTD) and screening of cervical length using transvaginal ultrasound in the second trimester is a proposed method to find women at risk Aims: To examine the potential value of routine measurement of cervical length in a Swedish population of women with singleton pregnancies in the prediction of PTD. To estimate inter- and intra-observer agreement and reliability of cervical length measurements. READ MORE

    Abstract : Diabetic retinopathy (DRP) is a major cause of acquired blindness and visual impairment among people of working age as well as those aged 65 years or more. About 3-4% of the population has diabetes mellitus, 35-65% of the diabetic patients have some type of DRP and 10-35% have sightthreatening retinopathy. READ MORE

  3. 3. New workflow method for ultrasound examinations

    Author : Carina Stenman; Örjan Smedby; Staffan Wirell; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Background: Growing demand for ultrasound examinations and higher quality requirements motivate searching for routines combining the diagnostic accuracy of radiologist-performed examinations with the economical advantages of sonographerperformed examinations. One possible approach is to use strictly standardized examination protocols and documentation made by cine-loops that will give the radiologist access to all relevant information after the examination.

    Abstract : Columnar metaplasia, where columnar epithelium replaces the normal squamous epithelium in esophagus, is considered to be a precancerous condition in which the development of adenocarcinoma can be followed through various grades of dysplasia. The interpretation of these histological changes is subjective and suffers from considerable inter-observer variation among pathologists. READ MORE
