- Ultrasound waves cannot pass through bones, so an ultrasound to evaluate the brain cannot be done after the bones of the skull (cranium) have grown together. Cranial ultrasound can be done on babies before the bones of the skull have grown together or on adults after the skull has been surgically opened. It may be used to evaluate problems in the brain and ventricles in babies up to about 18 months old.

How does imaging technology help diagnose stroke? Imaging data can also help determine the evolution, extent, and location of any brain damage and show an obstruction in the artery supplying blood to the involved parts of the brain. Physicians often repeat imaging tests several days after the onset of a stroke to survey the extent of damage.

Ultrasound During Pregnancy Your doctor may order an ultrasound scan at any time during your pregnancy. The most common time to have one is between the 16th and 20th week of pregnancy. But you may have an ultrasound earlier in your pregnancy to help determine your due date or check for problems with the baby's development.

Ultrasound scans in pregnancy The second scan offered to all pregnant women is called the anomaly scan, or mid-pregnancy scan, and usually takes place between 18 and 21 weeks of pregnancy. This scan checks for structural abnormalities (anomalies) in the baby.

Ultrasound: Sonogram Ultrasound dating of conception is not reliable for determining paternity because the ultrasound can be off by at least 5-7 days in early pregnancy. You may have an ultrasound between 18 to 20 weeks to evaluate dates, a multiples pregnancy, placenta location or complications.

- The team of researchers scanned the brains of 106 high-risk infants at age 6, 12 and 24 months using MRI to examine if there was any brain overgrowth. In addition, researchers followed brain activity of low-risk infants.

Ultrasound - Musculoskeletal Ultrasound images are typically used to help diagnose: 1  tendon tears, or tendinitis of the rotator cuff in the shoulder, Achilles tendon in the ankle and other tendons throughout the body. 2  muscle tears, masses or fluid collections. 3  ligament sprains or tears. 4  inflammation or fluid (effusions) within the bursae and joints.

- The baby’s heartbeat will be detected at this stage. At 8-11 weeks gestation, your baby continues to change appearance as it grows and develops. By 8 weeks gestation, your baby can usually be seen with transabdominal ultrasound. transvaginal ultrasound is usually required to see the baby at this stage of the pregnancy. Your baby is just a tiny embryo. Although the ultrasound may see your baby, it measures only a few millimetres long, and it is too early to always detect the baby’s heartbeat.

Complications If an ultrasound is done at 6 to 7 weeks and a heartbeat is not detected, does that mean there is a problem? No, it does not mean there is a problem. The heartbeat may not be detected for reasons that include: tipped uterus, larger abdomen, or inaccurate dating with last menstrual period.

- An ultrasound scan is routine for pregnant women. Detect abnormalities of heart structures such as the heart valves. This type of ultrasound scan is called echocardiography. See the separate leaflet called Echocardiogram for more details. Help to diagnose problems of internal organs such as the: Liver; Gallbladder; Pancreas; Thyroid gland; Lymph nodes; Ovaries

What is Traumatic Brain Injury (TBI)? Ultrasound. Ultrasound imaging is a common diagnostic procedure used in the NICU; it simply gives you a clear picture inside the body. It is performed by radiology or ultrasound technicians or clinicians to check on the baby’s developing organs, blood flow in the brain, and inside the body.

Ultrasound Scans- Cause for Concern A nother recent application for ultrasound is the “nuchal translucency test”, where the thickness of the skin fold at the back of the baby’s head is measured at around 3 months; a thick ‘nuchal (neck) fold’ makes the baby more likely, statistically, to have Downs syndrome.

- Brain SPECT Scan. Your doctor has ordered a brain SPECT scan. The role of this procedure is to diagnose Alzheimer's and other neuro-degenerative diseases, stroke, seizure, and to evaluate memory loss. Our team of specialized doctors, nurses and technologists is led by Alan Waxman, MD, Chief of Nuclear Medicine.

Ultrasound: A Trimester-by-Trimester Guide For many pregnant women, their last ultrasound takes place at their 20-week anatomy scan. If you've gone past your due date, your doctor may want to keep a close eye on your baby with fetal heart-rate monitoring and ultrasounds to assess the amniotic fluid levels.

Ultrasound scans You may be referred for an early scan because of vaginal bleeding or spotting, or possibly because you have had problems in a previous pregnancy. The best time to have a scan is from about 7 weeks’ gestation when it should be possible to see the baby’s heartbeat in a normal pregnancy.he ultrasound scan may show: 1  A viable ongoing pregnancy. 2  An ongoing pregnancy that suggests a problem. 3  A pregnancy of unknown location (PUL). 4  A complete miscarriage. 5  A non-viable pregnancy. 6  Missed miscarriage (also called silent or delayed miscarriage or early embryonic demise) This is where the baby has died or failed to develop but your body ...

Can ultrasound detect potential heart attacks, stroke before symptoms arise A study of portable ultrasound carried out in the USA, Canada and India has revealed the potential of this technology for detecting plaques in peripheral arteries that can lead to heart attacks and stroke before symptoms arise, in both developed and developing country settings, allowing preventive treatment in those affected.

- EEG measures brain waves and is able to detect abnormal brain activity through the use of electrodes. Using a mild adhesive, these electrodes are strategically placed on the scalp and connected to the EEG machine with thin wires.

Electroencephalogram (EEG) EEG can also detect abnormal brain waves after a head injury, stroke, or brain tumor. Other conditions such as dizziness, headache, dementia, and sleeping problems may show abnormal brain patterns. It can also be used to confirm brain death.

Ultrasound Scan 1 Detect abnormalities of heart structures such as the heart valves. ( 2 An ultrasound scan of the heart is called an echocardiogram 3  .). Help to diagnose problems of the liver, gallbladder (such as gallstones), pancreas, thyroid gland, lymph nodes, ovaries, testes, kidneys, bladder and breast.t is used in many situations. The way the ultrasound bounces back from different tissues can help to determine the size, shape and consistency of organs, structures and abnormalities. So, it can: 1  Help to monitor the growth of an unborn child, and check for abnormalities.

Cranial Ultrasound/Head Ultrasound In infants, head ultrasound is used to: 1  evaluate for hydrocephalus, or an enlargement of the ventricles, a condition that can have a number of causes. 2  detect bleeding within the brain tissue or the ventricles. The latter condition is called intraventricular hemorrhage (IVH).
