The Use of a High Frequency Linear Transducer in the Assessment of Fetal Anatomy at the Routine 11 to 13 + 6-Week Scan among Chinese Population
Objectives: To determine if the use of high frequency linear transducer (HFLT) in addition to conventional curvilinear transducer (CCT) aids assessment of fetal cardiac and non-cardiac anatomy in the first trimester. Methods: Transabdominal CCT (4 8 MHz) followed by HFLT (9 MHz) was used to study prospectively the visualization rate of basic and optional anatomical structures according to inter...
متن کاملAssessment of intracranial translucency (IT) in the detection of spina bifida at the 11-13-week scan.
OBJECTIVE Prenatal diagnosis of open spina bifida is carried out by ultrasound examination in the second trimester of pregnancy. The diagnosis is suspected by the presence of a 'lemon-shaped' head and a 'banana-shaped' cerebellum, thought to be consequences of caudal displacement of the hindbrain. The aim of the study was to determine whether in fetuses with spina bifida this displacement of th...
متن کاملPrediction of preterm delivery in twins by cervical assessment at 23 weeks.
OBJECTIVE To establish the relation between cervical length at 23 weeks of gestation in twin pregnancies and risk of spontaneous delivery before 33 weeks. METHODS Cervical length was measured by transvaginal sonography at 23 (range 22-24) weeks of gestation in 464 twin pregnancies attending for routine antenatal care. In the patients who were managed expectantly the relation between cervical ...
متن کاملCervical spondylosis and nerve root lesions. Incidence at routine necropsy.
Cervical spondylosis is a common condition. It is often associated with brachial neuralgia and occasionally it produces spinal cord compression. Although the bony changes may be very obvious on radiographic examination, clinically the disease may not be severe. The real importance of the bony and soft-tissue changes in this condition lies in their effect on adjacent structures. Although the inc...
متن کاملDetailed screening for fetal anomalies and cardiac defects at the 11-13-week scan.
OBJECTIVE To assess the diagnostic efficacy of the first-trimester anomaly scan including first-trimester fetal echocardiography as a screening procedure in a 'medium-risk' population. METHODS In a prospective study, we evaluated 3094 consecutive fetuses with a crown-rump length (CRL) of 45-84 mm and gestational age between 11 + 0 and 13 + 6 weeks, using transabdominal and transvaginal ultras...
