This scan can be performed from time of conception to 12 weeks gestation. These scans along with blood test can confirm normal viable intrauterine pregnancy.
Sometimes in early pregnancy it may not be possible to visualise pregnancy by scan on abdomen. In such cases a transvaginal scan may be performed. This scan is safe and does not harm pregnancy in any way.
This scan can be performed between 6 to 11 weeks gestation. It confirms viable intrauterine pregnancy, confirms duration of pregnancy and can diagnose multiple pregnancies (Twins/ triplets). In case you are experiencing any abnormal symptoms such as vaginal bleeding, lower abdominal pain then this scan can exclude miscarriages, ectopic pregnancies.
This scan is one of the most important scans in pregnancy. This gestation is ideal for estimating gestational age, confirm number of babies, detect most major structural abnormalities, measure nuchal translucency and perform screening for chromosomal abnormalities.
Aim of this scan is to determine sex of baby and this is usually possible after 16 weeks gestation. This may be influenced by the position of baby.
This scan is performed between 19 and 24 weeks gestation. The aim of this scan is to measure baby, check anatomy and ensure that baby is developing well in the womb. We check the head, brain, face, neck, spine, thorax, heart, abdomen, kidneys, placenta and extremities during this assessment. Sex of baby can be determined at this gestation.
This can be performed by measuring cervical length on transvaginal scan. The cervical length between 19 -24 weeks gestation can accurately predict risk of preterm delivery. Cervical length along with vaginal swabs is an important investigation in managing pregnancies complicated by very early preterm delivery.
Uterine artery Doppler at 11-14 weeks and at 19 to 24 weeks along with blood test can be performed to detect risk of developing preeclampsia (high blood pressure).
These scans are usually not performed for medical indications except in some cases of cleft lip and limb defects. This scan allows parents to see their baby prior to delivery. We will perform a growth scan before 3D/4D scan and will provide you with a report, five 3D pictures and a digital copy of images on DVD.
This scan is best performed between 26 to 32 weeks gestation and the quality of images will depend on baby position.
These are performed to check fetal chromosomes in cases of suspected chromosomal abnormalities.
These scans are performed between 24 to 38 weeks gestation. Small babies and growth restricted babies are at risk of fetal demise and hence during these scans we measure baby to get an estimate of weight. We also measure blood flow through the Umbilical artery, middle cerebral artery and ductus venosus, measure amniotic fluid and assess placenta and exclude growth restriction to ensure fetal wellbeing.
Blood sample taken from mother from 10 weeks gestation is used to analyse fetal DNA for Trisomy 21 (Down’s syndrome), Trisomy 13 (Pataus syndrome), Trisomy 18 (Edward’s syndrome) and sex chromosomes (X, Y). This test can be performed in singleton and twin pregnancies and is highly reliable. Ultrasound scan is performed before taking the blood sample to confirm that pregnancy is ongoing and there are no fetal defects.
