Morphology scan

What is a heart CT scan? A During the test, a specialized dye is injected into your bloodstream. The dye is then viewed under a special camera in a hospital or testing facility. A heart CT scan may also be called a coronary CT angiogram if it’s meant to view the arteries that bring blood to your heart. The test may be called a coronary calcium scan if it’s meant to determine whether there’s a Your doctor may order a heart CT scan to look for certain conditions, including: • • buildup of a hard substance known as lipid plaque that may be blocking your coronary arteries • defects or injury to the heart’s four primary valves • • tumors in or on the heart A heart CT scan is a common test for people experiencing heart problems. This is because it allows your doctor to explore the A heart CT scan carries very few risks. Contrast dye Most of the contrast material, sometimes referred to as dye, used for CT scans contains iodine. This iodine is later flushed from the body by the kidneys. If your kidneys have been affected by • Mild reactions to the contrast material include • Moderate reactions can include severe • Severe reactions can include You’re at greater risk of an allergic or adverse reaction to iodine-based material if you’ve had a previous reaction or if you’ve received a large amount of contrast material within the past 24 hours. Other risk factors include Talk with your doctor if you feel you’re at risk of a reaction. There may be medication available to help you avoid ...

What is fetal morphology scan? A fetal morphology scan aims to carry out a thorough check of the structures of the fetus. Most babies are normal and the parents can be reassured with the normal ultrasound findings. In case a baby has some structural defects, it might be important to find out before he or she is born. By knowing the abnormalities, prenatal diagnosis might be possible and the parents, the obstetricians and the paediatricians might be better prepared for the birth of such affected child. For certain major congenital defects, the parents might have the option of terminating the pregnancy. How is this morphology scan different from the ordinary antenatal ultrasound? During an ordinary antenatal ultrasound, the fetal heart pulsation, fetal size and presentation, amniotic fluid volume around the fetus and the placental site are usually assessed. For a fetal morphology scan, the above parameters are checked. In addition, the fetal structures are carefully assessed. Structures that are commonly assessed during a morphology scan include: cranium, intracranial structure, orbits, lips, spine, heart, lung, diaphragm, stomach, kidneys, bladder, other structures within the fetal tummy, umbilical cord, limbs and fetal genital organ. When is the best timing for fetal morphology scan? A fetal morphology scan is usually performed during 18-22 weeks of gestation. At this gestation, there are usually good views of the fetal parts and internal organs. Fetal structures can also ...

This is the main ultrasound scan that is obtained during the pregnancy. By 20 weeks most of your baby has developed such that screening of the organs is possible to assess for abnormalities. This scan can be done anytime between 18-22 weeks of your pregnancy but ideally around the 20 week mark. The scan can take a minimum of 45 minutes and sometimes up to an hour. At this scan the different parts of the baby will be measured to confirm that there has been satisfactory growth in line with that is expected from the due date. Multiple images of different organs will be taken to confirm that the development is progressing as expected. While most of the imaging is targeted to the baby, the placenta, umbilical cord and amniotic fluid are also imaged. The blood flow to the uterus will be assessed with Doppler measurements. Often the sex of the baby can be identified. Please let us know if you would like to know this. Occasionally not all of the baby can be assessed at one examination. This may be because of the position of the baby. A repeat examination is sometimes required. This will be part of the original examination fee and a booking will be made for you prior to leaving the practice. Ideally we will try and complete the entire scan on the day but sometimes bub doesn’t want to show us everything! Your baby can be comfy in one spot for the entire scan! What will happen on the day When you arrive for your scan you will be asked to fill out a form about your pregnancy to date. ...

Under normal conditions, the morphology and proportion of each blood cell type is fairly consistent in corresponding age groups. The morphology and proportion of each blood cell type may change in various hematologic diseases. Differential leukocyte count and special smear evaluation is helpful in revealing the changes in morphology or proportion of each cell type in the peripheral blood. 1-3 years Neutrophils/bands: 22-51% Lymphocytes: 37-73% Monocytes: 2-11% Eosinophils: 1-4% Basophils: 0-2% Metamyelocytes: 0% Myelocytes: 0% 4-7 years Neutrophils/bands: 30-65% Lymphocytes: 29-65% Monocytes: 2-11% Eosinophils: 1-4% Basophils: 0-2% Metamyelocytes: 0% Myelocytes: 0% 8-13 years Neutrophils/bands: 35-70% Lymphocytes: 23-53% Monocytes: 2-11% Eosinophils: 1-4% Basophils: 0-2% Metamyelocytes: 0% Myelocytes: 0% Adults Neutrophils/bands: 50-75% Lymphocytes: 18-42% Monocytes: 2-11% Eosinophils: 1-3% Basophils: 0-2% Metamyelocytes: <1% Myelocytes: <0.5% An interpretive report will be provided. 1.

Article: • • • • • • • • • • Images: • Epidemiology Placenta previa has an incidence of 1/200 pregnancies. Risk factors Placenta previa is associated with a number of risk factors, including: • previous placenta previa • previous • increased maternal age • increased parity • large placentas • • • maternal history of smoking • assisted conception 6 • previous manual removal of placenta Associations • Clinical presentation Placenta previa usually presents with painless vaginal bleeding in the second half of pregnancy (>20 weeks gestation), most commonly between 34-38 weeks gestation. Other associated clinical features include: • high fetal presenting part • maternal/fetal compromise secondary to exsanguination Pathology The term "placenta previa" covers a spectrum of anomalies and results from the partial or total insertion of the placenta into the lower uterine segment. Classification Previa is divided into four grades depending on the relationship and distance to the internal cervical os: • grade I: • grade II: • grade III: • grade IV: Sometimes grades I and II are termed a "minor" or "partial" placenta previa, and grades III and IV are termed a "major" placenta previa 5. Radiographic features Ultrasound Due to During the 'routine' 18 to 21-week morphology scan, the distance between the lower edge of the placenta and the internal os should be measured. If it lies within a few centimeters of the cervical os, then a repeat ultrasound at ~32 weeks should be performed to ensur...

The morphology scan is an ultrasound scan that examines many different areas in and around your baby, including their: • head and • spine • abdominal wall • heart • stomach • kidney and bladder • arms, legs hands and feet • • umbilical cord • amniotic fluid The person performing the scan will take measurements to help estimate your baby’s age.

While ultrasound scans can reassure you that your baby is developing normally, you may also learn that your baby has a structural abnormality. For this reason, before you have the test it’s a good idea to think about why you are choosing to do it, and how you will feel once you get the results.

Article: • • • • • • • • Images: • • Terminology Although there is an overlap of definition between pyelectasis and hydronephrosis, the former has been widely used instead of mild hydronephrosis given that the vast majority of the cases represent only a physiological incidental finding that resolves spontaneously, while the latter tends to be reserved for cases where a pathological obstruction is suspected. Epidemiology Fetal pyelectasis can be a relatively common finding on antenatal ultrasounds, often detected at the routine 2 nd trimester morphology scan. There is a recognized male predilection. The estimated prevalence is at ~2% of routine second trimester scans 13. Associations • 14 (see Pathology Pyelectasis can result from a number of factors. In the majority of cases, it is physiological and resolves spontaneously.
