Why after having a pelvic ultrasound did I need to have a transvaginal ultrasound immediately?
If you are in the early stages of a pregnancy, a transvaginal ultrasound is preferred over a transabdominal ultrasound (scanning through the top of the lower abdomen) because a transvaginal ultrasound provides much more detail and accuracy in assessing a fetus. Early on in pregnancy, the baby is extremely small, only a few millimeters long in the first few weeks. A transvaginal ultrasound will allow the doctor to see the baby's heart beat, even at 5 weeks old in the womb, whereas a transabdominal ultrasound would have an extremely hard time seeing something so tiny. If you are NOT pregnant, and you had t have this type of exam, this is nothing out of he ordinary. Sometimes, during a transabdominal ultrasound, gas from your stomach and bowel can get in the way, making it very hard to see organs such as the uterus and ovaries. If you do not have a full bladder, it will be nearly impossible to obtain medically relevant images through your stomach. A transvaginal ultrasound does not need a full bladder nor does it rely so much on the absence of bowel gas. In this case, it also provides much greater detail than a transabdominal ultrasound.
What is transabdominal?
Through the abdomen
How much water should you drink before an ultrasound?
Ultrasound uses sound, or more accurately, sound waves or vibrations, to travel through a medium of some sort to image what is within that medium. Not unlike radar, some of the sound waves bounce off of things within that medium allowing them to be seen. In example, the dividing line between muscle and bone can be thought of as an interface, something the sound waves can bounce off of. The change in density from muscle to bone, allows the bone to be image. Most ultrasound systems are designed to work best in water environments. This is because most of the solid parts of a body, including organs, bones, and other things, reside in, or are made up of mostly water. Water can carry sound waves better than air. Therefore, water-favoring ultrasound system can’t image well in air. For a water-based ultrasound system, air can act like a barrier to the sound waves. And, much like a brick wall stops you from seeing what is on the other side of the wall, air can prevent ultrasound from seeing what is there. By drinking water, one reduces the amount of air in the stomach and, therefore, improves the image quality of the ultrasound in that region of your body. However, there are other systems that use sound to image such things as geologic features underground, or things within the air (like the natural imaging bats do using sound). So, what you want to see or image, determines the type of sound-imaging system used.
What can obstetrical ultrasound examinations detect?
Doppler ultrasonography can detect the direction, velocity, and turbulence of blood flow. It is frequently used to detect problems with heart valves or to measure blood flow through the arteries.
Why is ultrasound useful?
ULTRASOUND produce STSTIONERY wave while pass through LIGUID
What are the two ways to perform a pelvic sonogram?
The two ways to perform a pelvic sonogram are transabdominal and transvaginal. Transabdominal sonogram involves applying a gel to the abdomen and using a transducer to obtain images through the skin. Transvaginal sonogram involves inserting a transducer into the vagina to obtain images of the pelvic organs.
What runs halfway through India?
The Tropic of Cancer runs halfway through India.
Why Ultrasound can pass even through solids?
Ultrasound can pass through solids because it is a type of mechanical wave that is generated by vibrating particles. The wavelength of ultrasound is smaller than the spacing of particles in a solid, allowing it to penetrate through the material. This property makes ultrasound useful for medical imaging and non-destructive testing of solid objects.
What phase is it when the moon is halfway through the lunar cycle?
The moon will be a full moon, halfway through the lunar cycle.
Can both a urine and blood pregnancy test be wrong?
Yes. When I was pregnant with my daughter I took 2 urine tests and a blood pregnancy test all through my doctor's office and they were all negative. I was told I had polycystic ovarian syndrome. The only way I found out I was pregnant was via ultrasound.
What are sign of Ovarian follicle atresia?
An ovarian follicle atresia is a process in which immature ovarian follicles physically decline. Roughly 20 ovarian follicles mature every month but only one of them is ovulated and the rest go through the process of atresia. As such, there is no specific sign of ovarian follicle atresia as it is a natural process in the female reproductive cycle.
What happens halfway through the birth canal?
Halfway through the birth canal there are contraction that leads to the baby being pushed out.
