A 3D animated look at a 1st trimester baby. What is nuchal translucency? Nuchal translucency NT is a collection of fluid under the skin at the back of a baby’s neck. The nuchal translucency scan measures the thickness of this fluid to assess the risk of Down’s syndrome. It can be measured using ultrasound. If the scan reveals that there is more fluid than usual, it could be a sign of Down’s syndrome. Another sign of Down’s syndrome is the shape of the baby’s nasal bone. Your doctor will order another scan to measure the nasal bone if he suspects signs of Down’s syndrome. Why might I have a nuchal scan? All pregnant women are offered a nuchal translucency NT scan, to assess whether or not their babies are likely to have Down’s syndrome.
Current Management of Nasal NK/T-cell Lymphoma
There has been some research that shows that absence of the nasal bone at weeks gestational age is associated with Down syndrome. You did not mention your race, and that can impact the nasal bone finding. The following study was conducted with Caucasian individuals. In other words, some of the pregnancies thought to have no nasal bone did not have Down syndrome. The other finding of these studies is that even skilled ultrasonographers experienced difficulties in nasal bone assessment.
Another study found more pregnancies with an absent nasal bone in the first trimester of women who are of Afro-Caribbean and Southern Asian ancestry.
CT scan helps in determining whether the tumor is a neoplasm, extent of proliferation, localization of nasal cavity abnormalities and possible tumor extension into the cranial vault (space of the skull).
Each one of the nasal bone has four bones, which create joints: Each nasal bone has four borders: Each nasal bone has two surfaces: Nasal Bone Relation Superiorly, in the nasal section the paired nasal bones merge in the midline with each other and with the frontal bone superiorly. The center of the frontonasal suture is created through the combination of the nasal bones and the frontal bone is the nasion. All nasal bones and the frontal processes of all maxilla articulate with each other laterally.
Piriform aperture is the large opening located inferiorly within the nasal region and the anterior aperture of the nasal cavity. The nasal bones bounded it superiorly and with each maxilla laterally and inferiorly. Creating the lower part of the bony nasal septum and terminating anteriorly as the anterior nasal spine and the paired inferior nasal conchae, the fused nasal crests are detectable via the piriform aperture. The outer surface of the nasal bone:
Nasal bone FMF Certificate of competence in the assessment of nasal bone In a high proportion of fetuses with trisomy 21 and other chromosomal abnormalities the nasal bone is hypoplastic or not visible at weeks’ gestation. Assessment of the nasal bone at weeks improves the performance of screening for trisomy 21 by maternal age and fetal NT and serum biochemistry. Requirements for Certification in assessment of the nasal bone The requirements for certification are:
Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations. Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels.
The “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle. Blood flow characteristics in the fetal blood vessels can be assessed with Doppler ‘flow velocity waveforms’. Diminished flow, particularly in the diastolic phase of a pulse cycle is associated with compromise in the fetus. Various ratios of the systolic to diastolic flow are used as a measure of this compromise.
The blood vessels commonly interrogated include the umbilical artery , the aorta , the middle cerebral arteries , the uterine arcuate arteries , and the inferior vena cava. The use of color flow mapping can clearly depict the flow of blood in fetal blood vessels in a realtime scan, the direction of the flow being represented by different colors.

The nuchal translucency scan is a non-invasive ultrasound procedure usually performed on the abdomen area, although it may also be performed vaginally. This assessment is important as it allows the diagnosis of potential fetal complications including Down syndrome.
If our specialists detect any abnormalities using our state-of-the-art ultrasound technology, we will notify you of the risks and discuss your options.
Dating and viability scan is the ultrasound done between the 6 th and the 9 th week from LMP. The importance of this test is: The importance of this test is: To check if the location of the fetus is correct.
A nuchal translucency NT measurement is taken through a transvaginal or transabdominal ultrasound, measuring the thickness of this fluid. Normally the amount of fluid is small, producing a thin NT measurement. We know that the amount of fluid can increase in the presence of certain conditions, producing a thicker NT measurement. Conditions associated with an increased NT measurement include some chromosome abnormalities for example, trisomy 13, 18 and 21 and some structural problems for example, heart abnormalities.
An increased NT measurement does not always mean the baby has a problem but it does increase the risk. There are established and strict criteria for the accurate measurement of the nuchal translucency. It is important for the measurement to be done properly to ensure an accurate result. If your baby is not co-operating and the NT cannot be measured accurately, we may ask you to return for more images later in the day.
Occasionally, patients need to return on another day if the baby remains in an unhelpful position. A nuchal translucency ultrasound is performed with a transabdominal ultrasound. Transabdominal ultrasound involves scanning through your lower abdomen.

I second another scan Islington, just to put your mind at ease. I do think other markers would,ve been picked up if anything was amiss I totally understand your concern. Please keep us updated. Add message Report Snowflakepie Tue Feb All perfect at 20 weeks. The bloods were all fine but didn’t get the results for a week after the scan so not sure if that would have a bearing on the nasal bone aspect?
If it is really worrying you then contact them again and see if they can just do a quick scan on the face area. Otherwise it might be worth the cost of a private scan to give you peace of mind. Good luck x Add message Report islingtongirl Tue Feb
Sinus CT scan
It is usually part of an assessment called combined first trimester screening. Combined first trimester screening Combined first trimester screening assesses the risk for your baby having certain chromosomal abnormalities trisomy 13, 18 and This testing combines the nuchal translucency ultrasound with specific blood tests. Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening.
Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis.
May 07, · The nasal bone is considered to be present if it is more echogenic than the overlying skin and absent if it is either not visible or its echogenicity is the same or less than that of the skin.
This area represents a transition zone between the thicker proximal and thinner distal segments. Fractures of the nasal bones are frequently transverse. The lateral view obtained by using a soft-tissue technique is probably best for depicting old and new fractures of the nasal bones. Lateral view is not useful in this The use of plain images and computed tomography CT scans for the diagnosis and management of nasal fractures has been controversial.
Several small studies have shown that use of these modalities is neither cost-effective nor beneficial to the patient or physician. Nasal fractures are usually evident and can be elicited by means of careful history taking and physical examination. Rarely is the radiologic confirmation of these injuries needed The misreads were found to be the result of the midline nasal suture, the nasomaxillary suture low defect , and thinning of the nasal wall high defect.
Short lucent lines that reach the anterior cortex of the nasal bone, with or without displacement, should be regarded as nasal fractures. Other lines, such as normal sutures or longitudinally oriented nasociliary grooves, can be mistaken for longitudinal fractures. However, a nasociliary groove should never cross the plane of the nasal bridge; if this is demonstrated, the line is a fracture. Fortunately, fractures usually demonstrate a sharpened delineation, with greater lucency than normal sutures and grooves.
The radiologist must look closely for marked deviation, displacement with sharp angulation, and soft-tissue swelling. Evaluation of air zones by profilogram can provide important information, because the air zones commonly are lost after trauma. Alterations of air-zone shapes may indicate cartilage volume increases or septal hematoma.
Missing Nasal bone?
Nasal cavity and paranasal sinus cancers are usually found because of signs or symptoms a person is having. The doctor will take a history and examine the patient. Medical history and physical exam Your doctor will ask questions about your medical history and the problems you’ve been having. During the exam, the doctor will carefully check the parts of your nose and sinuses that are causing problems. This is a thin, flexible tube that allows the doctor to see into your nasal passages.
Nasal bone spurs. Nasal bone spurs develop within the nose and commonly cause headaches and migraines to occur. The pain may be triggered by environmental, health or hormonal changes. Bone spurs can be treated with surgery or non-surgical procedures. Nasal bone spurs are a common cause of migraines and headaches.
The goal with frozen semen is to breed within a window of 6 to 8 hours prior to ovulation up to 6 hours post ovulation. Accordingly, once the mare receives either HcG or Deslorelin, ultrasound exams occur every 6 hours to evaluate for impending ovulation. There are several options for breeding with frozen semen; the Arizona Equine doctors will work with the owner select the ideal protocol for their mare.
Shockwave Shockwave therapy is a treatment modality used by equine veterinarians to treat some tendon and ligament injuries in the leg. Shockwaves are created by a machine and a veterinarian guides the waves over the injured area for a specific amount of time. Shockwaves improves the healing time of tendon and ligament injuries by increasing blood supply to the damaged area. Shockwave therapy typically involves multiple treatments with the device over a period of weeks or months to assist with healing of the injured area.
In its broadest interpretation, the term means any type of medical or surgical procedure used for athletic horses. This usage would include all of equine medicine and surgery. Arizona Equine has a number of specialists that practice Equine Sports Medicine exclusively. These specialists include Drs. Howard and Taylor are board certified by the American College of Veterinary Surgeons and have been practicing equine sports medicine since
The scan is usually done transabdominally, but occasionally it may be necessary to do the scan transvaginally: The purpose of the week scan: To date the pregnancy accurately. This is particularly relevant for women who cannot recall the date of their last period, have an irregular menstrual cycle, or who have conceived whilst breastfeeding or soon after stopping the pill.

Will I be given a risk level for any other abnormalities? What is nuchal translucency? Nuchal translucency is a collection of fluid under the skin at the back of your baby’s neck. The amount of fluid is measured during a nuchal translucency NT ultrasound scan: That’s why the NT scan is used to help screen for Down’s syndrome. Why might I have a nuchal scan?
All pregnant women are offered an NT scan, to help assess whether or not their babies are likely to have Down’s syndrome. Every woman has a chance of giving birth to a baby with Down’s syndrome.
Short Nasal Bone
Fetal nasal bone assessment is a non-invasive procedure that helps provide even greater assurance to patients undergoing their first trimester risk assessment for aneuploidies. Absence or presence of this factor is different in some races. The study was aimed to evaluate nasal bone in the first trimester of pregnancy in the indigenous population of Khuzestan Province, and to monitor its value in the diagnosis of chromosomal abnormalities.
This study was conducted on pregnant women between years old who referred for first trimester screening for chromosomal abnormalities.
At the dating scan, when OH mentioned nose measurements the sonographer simply mentioned they don’t use nasal measurements anymore to check for Downs they measure fluid at the back of the neck as it’s more accurate. At the anomaly scan the sonographer was just concerned with getting the lip measurements from the front.
