The simple answer is yes , but of course it has to be used diligently on a case to case basis. There is epidemiological evidence to date that , there is no association between diagnostic ultrasound exposure in Utero and childhood Malignancies, Dyslexia, Speech development etc.
Color Doppler adds information about the amount and direction of blood flow to an organ, system or fetus, thus assisting us in better evaluation of conditions like venous and arterial blockages, fetal growth restrictions and evaluation of various tumors.
The ability to display information in 3D is a big advancement in the field of ultrasound. 4D USG is the addition of 'motion' to 3D technology, with the help of 3D and 4D USG we now have the ability to examine the fetal abnormalities in great detail.
We can also plan corrective surgeries for abnormalities like cleft lip and palate even before the baby is born. 3D and 4D technology with Color Doppler helps us in the evaluation of fetal heart, patients of infertility and a host of other medical conditions.
Normal healthy pregnancy will generally require at least five ultrasounds.
VIABILITY SCAN is done to confirm the site and viability of fetus.
FIRST TRIMESTER GENETIC NT/NB SONOGRAM, COMBINED FIRST TRIMESTER ANEUPLOIDY SCREENING is done between 11 – 13 + 6 weeks. In combination with biochemical markers (blood levels of FREE BETA HCG and PAPP-A). This ultrasound is critical for the evaluation of genetic /chromosomal abnormalities like Down's Syndrome and early detection of major structural anomalies.
ANOMALY SCAN/LEVEL II SCAN is done in the fifth month for the evaluation of various anomalies.
GROWTH SCAN is done between the seventh to eighth month of pregnancy.
Last ultrasound scan in the ninth month helps the obstetrician to plan the delivery.
Ultrasound and Color Dopplers are however tailored to the need of an individual patient by the treating obstetrician.
Immense progress has been made in terms of equipment, knowledge and operator's skill. Minor structural abnormalities especially of the limbs, heart and chromosomal abnormalities may not be detected on a single scan. A combination of biochemical markers (blood tests) and targeted scans to exclude anomalies increase the detection rate of abnormalities.
It is a detailed evaluation of the baby's heart, generally done around the fifth month of pregnancy to exclude major congenital abnormalities of the heart.
It is a form of soft tissue X ray performed to asses a palpable lump in the breast or is used as a tool for screening women at risk of breast cancer.
The digital X ray is obtained on conventional machine, but the images are stored in a digital format.
These images can then be processed later to obtain large amount of information. Digital imaging also cuts down on the radiation dose to the patient. High resolution cameras provide resolution up to 20 pixels and further improve the quality of images.
Fasting for 2 – 4 hours for abdominal scans is preferred. A full bladder is needed for kidney, prostate scans in males and pelvic scans in females.
Most pregnancy scans hardly need any preparation.
3D – 4D ultrasound is one of the most exciting advances in ultrasound in the last decade.
Seeing the fetus in such real life form arouses wonderful emotions in parents and helps in prenatal fetal bonding.
It gives us the ability to perform the entire scan using a few Rapidly obtained 3D volumes which can be manipulated and evaluated even after the patient has left the premises, thus saving time and increasing efficiency.
3D – 4D ULTRASOUND is helpful in further evaluation of malformations seen in 2D that can be more extensively examined using surface Rendering and multiple reconstructed planes.
Many different evaluation protocols are available for examining different organs like STIC for the fetal heart. And surface rendering for face and limbs Volumetric measurements of fetal organs, like fetal lungs can now be achieved. 3D 4D imaging has improved diagnostic accuracy for detection of facial defects Like cleft lip and palate, Micrognathia, Orbital anomalies, Microcephaly Nasal bone dysplasias.
Non-pregnant uterus may be evaluated for polyps, fibroids and congenital anomalies. Accurate measurements of ovaries and other organs is now possible. For frozen embryo transfers Endometrial receptivity studies are a boon for the infertility specialists.
Early placental vascularization studies are also important for high risk pregnancies. At Dr. Rajeev's Ultrasound Lab we have incorporated 3D – 4D ultrasound studies as a part of our daily clinical practice in obstetric and Nonobstetric patients.
We look forward to your cooperation in this endeavor to improve diagnostic accuracy of ultrasound with such a potent tool.
