Dept. of Radiology
Our radiology department is equipped with two, state of the art modem color Doppler machines in each and one portable for bedside sonography. The department is also equipped with a digital X-Ray machine and CT scan machine.The USG protocol that is followed in pregnancy includes one early first-trimester scan as a screening scan which includes an assessment of Nuchal Translucency (or NT). NT assessment is a very valuable parameter in early pregnancy and gives the sonologist an opportunity to identify a fetus at risk for trisomy 21, or other chromosomal disorders, and a wide range of genetic syndromes. This scan also establishes viability, accurate dating of pregnancy and detection of multiple pregnancies and ectopic gestations.
This is followed by 18-21 weeks 3D-4D anomaly scan for all antenatal mothers. These two scans together can pick up 80-90% of major and minor anomalies in the fetus. In the 18-21 weeks anomaly scan, we visualize all the fetal organs, placenta and liquor in details and also see live 3D-4D images of the unborn child. Pregnancy and organ development of the baby is a continuous ongoing process of 9 months and just a single scan is not enough to stamp normalcy of fetal organs.
Hence we follow up with all patients with the growth scan and color Doppler at around 28 weeks. Color Doppler of umbilical artery, middle cerebral artery, fetal aorta, ductus venosus and maternal uterine arteries with the calculation of RI (Resistance Index), PI (Pulsatility Index) and S/D ratio (Systolic/Diastolic ratio) gives an idea of normalcy of blood flow in the fetus. Any abnormality in these indices or in blood flow pattern is a pointer towards various pathologies setting in the fetus e.g. IUGR, Brain sparing effect, pregnancy-induced hypertension etc.
With plenty of liquor around the baby, it is easy to see real 3D-4D images of the fetus and visualize the in utero movements and activity of the unborn child.
Our infertility department, like obstetrics, is also incomplete without the valuable aid of USG. Diagnosis of difficult and complicated gynaec pathologies like endometriosis, adenomyosis, chocolate cysts, fibromyomas, hydrosalpinx & Tubo-Ovarian mass, polycystic ovaries and ovarian cysts, Pelvic Inflammatory disease, intrauterine and intrapelvic adhesions, Septate uterus, Asherman’s syndrome, pelvic abscess and Ectopic pregnancy is possible with great accuracy and certainty by ultrasonography.
It is actually a whole lot of valuable, crucial information which infertility and IVF specialist can get out of the follicular scans which are done by USG. Ovarian volume, follicular volume and size, perifollicular flow, endometrial thickness and pattern, myometrial echotexture, spiral artery blood flow, uterine artery blood flow and color Doppler; all the Doppler indices like Resistance Index, Pulsatility index, Systolic/Diastolic ratio give us an idea of blood flow to the endometrium and ovarian follicles. Ovum picks up and embryo transfer is also done under ultrasound guidance.
Profile Of Our Radiologists
Dr. Nandini Diwedi
MBBS,MD,DMRD
Dr. Nandini has more than 12 years of experience in radiology and has a special interest in doing o&g scans. She has graduated from Ahmedabad and done her post-graduation also from there, she is an expert in fetal anomaly scans and takes special interest in ultrasounds in infertility patients. She has worked in GB Pant hospital before joining our team.
Dr. Sumita Prabhakar
MBBS, MD, MRCOG (London)
Dr. Prabhakar did her graduation and post-graduation from prestigious Banaras Hindu University, Varanasi, where the department is equipped with Ultrasound machine and gives students the opportunity to learn to scan during there residency. She further took training in Doppler study at Queen Elizabeth Hospital in Malaysia. During her MRCOG training, she was especially interested in Fetal ultrasounds. She attended course conducted by the world authority in fetal ultrasound Prof. Nicolaides about detection of fetal abnormalities.
