Medical ultrasound (also known as diagnostic sonography or ultrasonography) is a diagnostic imaging technique based on the application of ultrasound. It is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs. Its aim is often to find a source of a disease or to exclude pathology
Many different types of images can be formed. The commonest is a B-mode image (Brightness), which displays the acoustic impedance of a two-dimensional cross-section of tissue. Other types like Doppler can display blood flow, motion of tissue over time, the location of blood, the presence of specific molecules, the stiffness of tissue, or the anatomy of a three-dimensional region.
Compared to other dominant methods of medical imaging, ultrasound has several advantages. It provides images in real-time and is portable and can be brought to the bedside. It is substantially lower in cost than other imaging modalities and does not use harmful ionizing radiation. Drawbacks include various limits on its field of view, such as the need for patient cooperation, dependence on physique, difficulty imaging structures behind bone and air, and the necessity of a skilled operator, usually a trained professional.
Abdominal Ultrasonography is a form of medical ultrasonography to visualize abdominal anatomical structures. It uses transmission and reflection of ultrasound waves to visualize internal organs through the abdominal wall. The black and white images show the internal structures of the abdomen such as appendix, intestines, liver, gall bladder, pancreas, spleen, kidneys and urinary bladder.
Before the ultrasound abdomen 4-6 fasting required. In some cases over night fasting and bowel preparation may be required (esp. in imaging of pancreas, gallbladder , bowel pathology etc), because undigested food , loaded bowel loops and gas interferes with imaging as air is a bad conductor of sound waves and causes difficulty in visualizing internal structures . You may also be asked to drink a lot of water before the scan to fill your Urinary Bladder this is for better visualization of Prostate , Uterus and Ovaries because fluid filled bladder is a good transmitter of sound waves and the structutres underneath will be clearly visualized . A full Bladder is mandatory for imaging of the pelvis structures . Do not empty bladder until the USG scan is over and DO NOT hurry for scan before you feel the sensation of full bladder which will only result in an incomplete scan..
Drink one liter of water one hour prior to your exam. Bring all your medical records for review which help the doctors to correlate multiple medical parameters and to make a better diagnosis of your ailment and stage which is important for your treatment planning. For follow up scans it is necessary for comparison ( eg. Discharge summary, blood reports, old scanning reports etc)
Ultrasound imaging of the pelvis used sound waves to produce pictures of the structures and organs in the lower abdominal and pelvis. There are three types of pelvic ultrasound. Trans abdominal (TAS) , Trans Vaginal (TVS for women) Trans Rectal (TRUS for men and unmarried women). These exams are frequently used to evaluate the reproductive and urinary system. A pelvic ultrasound allows quick visualization of the female pelvic organs and structures including the uterus , vagina, fallopian tubes and ovaries.TVS and TRUS is indicated whenever a better look at the pelvic structures is required.
Trans rectal Ultrasonography or TRUS in short is a method of imaging the organs in the pelvis. The most common indication for Trans rectal Ultrasonography is necessity of evaluation of the prostate gland and seminal vesicles in men with elevated prostate specific antigen or prostatic nodules on digital rectal exam. TRUS is also used to evaluate pelvic structures of unmarried women to evaluate pelvic pathologies like ovarian cyst, congenital anomalies , PCOD etc
Over night fasting . Bladder full for initial TAS followed by TRUS.
Bring all your medical records for review which help the doctors to correlate multiple medical parameters and to make a better diagnosis of your ailment and stage which is important for your treatment planning.
NSG or Cranial USG is an excellent modality for imaging a wide array of intracranial pathology in the infant and newborn. Neurosonography is a simple, established non-invasive technique for the intracranial assessment of neonatal brain. It is used to diagnose congenital anomalies , changes of brain during birth , intra cranial bleeding etc
B-Scan ultrasonography , often called just B-Scan or Brightness scan , offers two dimensional cross-sectional view of the eye as well as the orbit . B-Scan is used on the outside of the closed eyelid to view the eye.
An eye and orbit USG is routinely used to visualize the posterior compartment of the eye in evaluation of glaucoma , cataract , retinal detachment , vitreous hemorrhage , infections , cancerous and non cancerous growths etc
Patient is on a flat bed and eye will be closed. The doctor will put a gel on your eyelids. They will tell you to keep your eyes closed while you move your eyeballs in many directions.
Sonomammography or breast ultrasound is a non-invasive procedure performed to assess the breasts it. This test allows quick visualization of the breast tissue. Sonmomammorgalhy alone is done to image young patients with dense breasts The examination is often done along with mammography (x-ray of breast tissue) in others to study a mass or lump.
Early Transvaginal sonography (TVS) produces greatly improved resolution as compared to Trans Abdominal. TVS is indicated whenever a better look at the pelvic structures is required, mainly early pregnancy, lower uterine segment in late pregnancy, ectopic pregnancy. This usually takes place at 6 to 10 weeks of pregnancy. Early scan can confirm the number and position of fetus in the uterus.
This is painless procedure and only a part of the probe is inserted. The patient is on a flat bed and elevation has to be provided under the pelvis so that the probe can be tilted downwards during the sonographic examination. The patient should lie supine with the knees bent and the feet placed flat on the table shoulder width apart. No preparations necessary
Anomaly scan also known as a mid-pregnancy scan, takes a close look at your baby and your uterus. It is also known as Anomaly scan or 18-20 wks scan. This is detailed USG that look at babies body, baby’s fingers and toes, arms, legs, hands and feet, bladder, fetal growth and observe the position of the placenta, the umbilical cord, the amniotic fluid around the baby and uterus and cervix.
3 hours fasting. A full Bladder is mandatory for this scan.
A biophysical profile is a parental 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 is non-reactive, or for other obstetrical indications.
3 hours fasting. Moderately full bladder ideal . Light food just before scan (Biscuits).
Neck/ Thyroid USG uses sound waves to produce pictures of the thyroid gland within the neck. It does not use ionizing radiation and is commonly used to evaluate lumps or nodules found during a routine physical or other imaging exam. Neck USG is also used to evaluate other structures of neck like lymph nodes , salivary glands , vessels of neck and any abnormal swellings
Before the test remove necklaces , ear rings and other accessories that can interfere with imaging with the ultrasound probe.
Hip ultrasound is used when they suspect a problem called developmental dysplasia of the hip (DDH). DDH is a hip deformity that can happen before, during, or weeks to months after birth. In normal –functioning hip, the femoral head rests comfortably in socket. Hip USG used sound waves to produce pictures of muscles, tendons, ligaments, joints, bone and soft tissues of the hip. It is used to help diagnose any abnormalities and mainly used in infants to check for DDH.
Child sedation necessary. Some times need special X ray correlation.
USG imaging of the scrotum uses sound waves to produce pictures of a testicles and surrounding tissues. It is the primary method used to help evaluate disorders of the testicles, epididymis and scrotum.
High-resolution ultrasound imaging modality without exposure to ionizing radiation; used to visualize soft-tissue structures.

A Follicular study is a series of scans that help you know when you are ovulating. Generally, these scans will start around day 9th of your cycle and continue till ovulation occurs. The doctor observes the follicles development occurring in your ovaries to calculate the exact time when the egg will be released.
A group of four tendons that stabilize the shoulder joint. Each of these tendons attaches to a muscle that moves the shoulder in a specific direction. The four muscles whose tendons form the rotator cuff are the subscapularis muscle, which moves the arm by turning it inward (internal rotation); the supraspinatus muscle, which is responsible for elevating the arm and moving it away from the body; the infraspinatus muscle, which assists the lifting of the arm during outward turning (external rotation) of the arm; and the teres minor muscle, which also helps in the outward turning (external rotation) of the arm. Damage to the rotator cuff and degeneration is one of the most common causes of shoulder pain
HRUSG with special probes can well image the structures and make diagnosis of the rotator cuff injures , tendinitis and degeneration which helps in the management of shoulder pain .
No preparations necessary. Need good co-operation of the patient
A chest ultrasound is a noninvasive diagnostic exam that produces images, which used to assess the organs and structures within the chest, such as the lungs, mediastinum (area in the chest containing the heart, aorta, trachea, esophagus, thymus and lymph nodes) and pleural space.
No preparation necessary. Chest X-ray if necessary for correlation of pathology.
Guided Fine-needle aspiration cytology, a diagnostic procedure used to investigate lumps or masses under the skin. A needle is placed in to the suspected mass under guidance visualizing the needle track and taking a sample for the cytology study to diagnose its nature.
