Sonography | Ultrasonography - Suburban Diagnostics

SubUrban Icon Sonography

Suburban Diagnostics offers a complete range of ultrasonographic procedures like:

  • OBSTETRIC USG
  • NON-OBSTETRIC USG
  • ROUTINE SONOGRAPHY
  • MUSCULOSKELETAL USG
All sonography procedures at Suburban Diagnostics are strictly in compliance with PCPNDT laws and we strongly discourage and oppose the practice of sex determination of the foetus
OBSTERTIC SONOGRAPHY
  • Routine obstetrics (growth scan, early pregnancy, assessment of cervical length, placental position)
  • Nuchal scan/NT scan/early anomaly scan
  • Second trimester anomaly scan/targetted scan/malformation scan
  • Fetal echocardiography
  • Obstetric doppler
  • Biophysical profile
  • Early pregnancy
    • USG is done in early pregnancy to confirm the pregnancy as well as its position (intrauterine or extra uterine). A gestational sac can be reliably seen on transvaginal ultrasound by 5 weeks’ gestational age (approximately 3 weeks after ovulation)
  • First Trimester

    In the first trimester, a standard ultrasound examination typically includes:

      • Gestational sac size, location and number
      • Identification of the embryo and/or yolk sac
      • Measurement of fetal length (known as the crown-rump length)
      • Fetal number, including number of amniotic sacs and chorionic sacs for multiple gestations
      • Embryonic/fetal cardiac activity
      • Assessment of embryonic/fetal anatomy appropriate for the first trimester
      • Evaluation of the maternal uterus, tubes, ovaries, and surrounding structures
  • Second and third trimester

    In the second trimester, a standard ultrasound exam typically includes:

      • Fetal number, including number of amniotic sacs and chorionic sacs for multiple gestations
      • Fetal cardiac activity
      • Fetal position relative to the uterus and cervix
      • Location and appearance of the placenta, including site of umbilical cord insertion when possible
      • Amniotic fluid volume
      • Gestational age assessment
      • Fetal weight estimation
      • Fetal anatomical survey

Evaluation of the maternal uterus, tubes, ovaries, and surrounding structures when appropriate

Ultrasonography of the cervix

Obstetric sonography has become useful in the assessment of the cervix in women at risk for premature birth. A short cervix preterm is undesirable.

At 24 weeks’ gestation a cervix length of less than 25 mm defines a risk group for preterm birth, further, the shorter the cervix the greater the risk. It also has been helpful to use ultrasonography in women with preterm contractions, as those whose cervix length exceed 30 mm are unlikely to deliver within the next week.

  • NUCHAL SCAN
    • Assesses the risk of having Down’s Syndrome and other chromosomal abnormalities
    • The minimum fetal crown–rump length (CRL) should be 45 mm and the maximum 84 mm
    • At Suburban Diagnostics, radiologist are Fetal Medicine Foundation (FMF) UK certified
  • ANOMALY SCAN

    Screen structural and developmental abnormalities

    • Neural Tube Defect (NTD)
    • Fetal aneuploidy
  • OBSTETRIC DOPPLER
    • Umbilical arterial (UA) doppler assessment is used in surveillance of fetal well-being in the third trimester of pregnancy. Abnormal umbilical artery Doppler is a marker of uteroplacental insufficiency and consequent intrauterine growth restriction (IUGR) or suspected pre-eclampsia
    • Umbilical artery Doppler assessment has been shown to reduce perinatal mortality and morbidity in high risk obstetric situations
Indications

Assessment of fetal growth and well-being in the third trimester, which routinely includes umbilical Doppler assessment, is indicated in scenarios where there is an increased risk of fetal growth restriction or poor perinatal outcome.

Maternal conditions
  • Diabetes mellitus
  • Chronic kidney disease
  • Hypertension
  • Prothrombotic states
Pregnancy related conditions
  • Suspected IUGR
  • Previous pregnancy with IUGR or fetal death in utero
  • Decreased fetal movement
  • Oligohydramnios
  • Polyhydramnios
  • Multifetal pregnancy
  • BIOPHYSICAL PROFILE

A biophysical profile (BPP) is a prenatal ultrasound evaluation of fetal well-being involving a scoring system, with the score being termed Manning’s Score. It is often done when a non-stress test (NST) is non-reactive, or for other obstetrical indications.

The BPP has 5 components—4 ultrasound(US) assessments and an NST. The NST evaluates fetal heart rate and response to fetal movement. The five discrete biophysical variables:

  • Fetal heart rate
  • Fetal breathing
  • Fetal movement
  • Fetal tone
  • Amniotic fluid volume

Each assessment is graded either 0 or 2 points, and then added up to yield a number between 0 and 10. A BPP of 8 or 10 is generally considered reassuring. A BPP normally is not performed before the second half of a pregnancy, since fetal movements do not occur in the first half. The presence of these biophysical variables implies absence of significant central nervous system hypoxemia/acidemia at the time of testing. By comparison, a compromised foetus typically exhibits loss of accelerations of the fetal heart rate (FHR), decreased body movement and breathing, hypotonia, and, less acutely, decreased amniotic fluid volume.

NON-OBSTETRIC / GYNEC SONOGRAPHY
  • USG pelvis
  • Follicular monitoring / ovulation studies
  • AFC count
  • Pelvis Doppler
ROUTINE SONOGRAPHY
  • Whole abdomen / abdomen and pelvis Detailed ultrasound assessment of all abdominal organs including liver, gall bladder, pancreas, spleen, kidneys, bladder, prostate and intestines
  • Upper abdomen Detailed ultrasound assessment of all abdominal organs including liver, gall bladder, pancreas, spleen, kidneys, bladder
  • Kidney, ureter and bladder (KUB) Detailed ultrasound assessment with specific focus on organs of urinary system including kidneys, bladder and prostate
  • KUB and Pelvis Detailed ultrasound assessment with specific focus on organs of urinary system including kidneys, bladder, prostate (in males) and uterus/ovaries in females with assessment of prevoid capacity of bladder and postvoid residue
  • Transrectal Ultrasonography (TRUS) Also known as Transrectal Ultrasonography of the prostate, this is a detailed evaluation of prostate through a transrectal approach. In this procedure an ultrasonography probe is introduced per rectally for better understanding of the prostate sonomorphology and to rule out any suspicious lesions in the prostate
  • Inguinal regions High resolution USG is done to rule out hernias or any other pathology in the inguinal regions
  • Scrotum Detailed ultrasound assessment of the testis
  • Neck / thyroid Detailed ultrasound assessment of the thyroid gland, submandibular, parotid glands as well as to confirm/rule out the presence of any enlarged cervical lymph nodes
  • Sonomammography / USG Breast
  • USG Penis
  • Small parts / Soft tissue Sonography
MUSCULOSKELETAL USG
  • SHOULDER
  • ELBOW
  • WRIST
  • HIP
  • KNEE
  • ANKLE
  • FOOT
