Background: Femur is a long bone that measures gestational age and contributes to human height weight, but can also be affected by growth retardation or skeletal abnormalities. Objective: To compare the effect of femur length on fetus using ultrasonography. Methods: The research was four-month crossectional study carried out in private hospital Tehsil Kharian, District Gujrat, Pakistan. Data ob...
Neuroblastoma is the most common pediatric extracranial solid tumor derived from primitive neural crest cells of the sympathetic nervous system. Although one-fifths of all neuroblastomas occurs within the thorax, thoracic neuroblastomas detected in fetus have been rarely reported. We report a case of fetal thoracic neuroblastoma with massive pleural effusion detected with prenatal ultrasonograp...
A twenty-year-old second gravida presented to the department of radiodiagnosis for routine obstetric ultrasound examination. Ultrasonography revealed a live fetus of 17 weeks with absent falx, fused thalami, monoventricle, proboscis, and cyclopia. Fetal MRI was performed and the findings were confirmed. Even though ultrasonography is diagnostic in the detection of fetal anomalies, MRI plays a v...
STUDY OBJECTIVE The purpose of this study is to determine fetal outcomes of women diagnosed with live intrauterine pregnancy after emergency department (ED) presentation for abdominopelvic pain or vaginal bleeding during the first trimester. METHODS A retrospective medical record review of prospectively recorded data of consecutive ED charts from December 2005 to June 2006 was performed to id...
Pregnant women's beliefs, expectations and experiences of antenatal ultrasound in Northern Tanzania.
This qualitative study explored pregnant women's beliefs, expectations and experiences of the recently introduced antenatal ultrasound service in BomaNg'ombe hospital, Tanzania. Thematic analysis of 25 semi-structured interviews and 41 questionnaires was employed. The majority of women desired ultrasonography despite many not understanding the procedure or purpose.

BACKGROUND Maternal zinc deficiency is relatively common in developing countries, but its consequences for fetal growth are not established. OBJECTIVE The goal was to examine whether improvement in maternal gestational zinc status is positively associated with fetal growth as assessed by ultrasonography. DESIGN We conducted a double-masked, randomized trial among 242 pregnant Peruvian women...
Extralobar pulmonary sequestrations (ELS) are masses of non-functioning lung tissue that are supplied by an anomalous systemic artery and do not have a bronchial connection to the native tracheobronchial tree. On prenatal ultrasonography, an ELS appears as a well-defined echodense, homogeneous mass. Detection by color flow Doppler ultrasonography of a systemic artery from the aorta to the fetal...
ISUOG disapproves of the use of ultrasound for the sole purpose of providing souvenir images of the fetus. There have been no reported incidents of human fetal harm in over 40 years of extensive use of medically indicated and supervised diagnostic ultrasound. Nevertheless, ultrasound involves exposure to a form of energy, so there is the potential to initiate biological effects. Some of these e...
Ultrasound screening of structural fetal malformations is mainly based on the use of ultrasounds during the second trimester of pregnancy. The diagnostic sensibility of ultrasounds varies in the different multicentric studies reported in literature and is correlated to different factors: gestation period, type of malformation, number of ultrasounds performed, operator experience, etc. Third tri...
