  4. 4. Three-dimensional ultrasound studies of normal and abnormal ovaries

    Author : Ligita Jokubkiene; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ovary; ovarian follicle; ovarian neoplasms; ultrasonography; three-dimensional imaging; Doppler ultrasound imaging; vascular morphology;

    Abstract : The aims of this work were: 1) to estimate the number of follicles, ovarian volume and power Doppler vascular indices and their changes with age using three-dimensional (3D) transvaginal grey-scale and power Doppler ultrasound in asymptomatic women of fertile age either with natural menstrual cycles or using combined oral contraceptives, and 2) to determine whether tumour vascularity, assessed by 3D power Doppler ultrasound, can help discriminate between benign and malignant ovarian tumours. A group of 303 gynaecologically asymptomatic women, aged 20–39 years with normal menstrual cycles (NMC) and another group of 213 women aged 20–39 years using combined oral contraceptives (COC) were examined using two-dimensional (2D) and 3D transvaginal ultrasound once between cycle day 4 and 8.

  5. 5. An epidemiological study on nasopharyngeal carcinoma

    Author : Yufeng Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Nasopharyngeal carcinoma (NPC) is a malignancy known for its unique geographic and ethnic distribution characterized by particularly high incidence in southern China, Southeast Asia, and North and East Africa, but being rare in the rest of the world. Its etiology has remained enigmatic and the accumulated evidence suggests that genetic predisposition, environmental factors, and infection with Epstein-Barr virus (EBV) are involved. READ MORE
