A 7 week ultrasound would be more accurate than a 13 week one especially if it agreed with your lmp. 13 week babies have plenty of room to move around and sometimes it is more difficult to measure accurately.

What is the medical term meaning meaning recording of an ultrasound?
While an ultrasound examination is being done, there is a visual image that is captured as pictures showing the structures that are being examined by the sound wave technology. These video-taped images are recorded by the technologist performing the ultrasound so that a physician can review the images and interpret the test results for diagnostic purposes. In pregnancy, ultrasound "pictures" are taken of the fetus and these are recorded for the same reasons above, however, these recordings are also provided to the pregnant woman as her very first "baby" pictures.

Why does the patient need to drink plenty of water before undergoing ultrasound?
Two ultrasound exams that would benefit from drinking water prior to the exam would be a transabdominal pelvic ultrasound (different than a transvaginal pelvic ultrasound) and a transabdominal ultrasound to focus just on the pancreas. The reasoning behind ingesting water for the pelvic ultrasound is so that the bladder will be full and during the exam the full bladder acts as a window to visualize the pelvic organs which sit behind the bladder. The fluid filled bladder allows the soundwaves from the ultrasound machine to to be enhanced as they travel through to the pelvic organs. A full bladder also pushes intestinal gas out of the field of view as well. The transabdominal exam is typically followed by the transvaginal ultrasound. The patient should empty their bladder after the transabdominal pelvic ultrasound and before the transvaginal ultrasound. A full bladder would actually interfere with a transvaginal ultrasound. The other exam that would benefit from ingesting water would be a transabdominal scan of the pancreas. Typically the pancreas is imaged within an abdominal ultrasound. However, ingesting water would interfere with imaging the other organs typically seen in this exam. So the pancreas should be visualized last and immediately following the patient drinking 8 oz. of water. The reasoning behind this technique is that the fluid filled stomach acts as a window to visualize the deep pancreas, similar to the reasoning behind having a full bladder for a pelvic ultrasound.

Can anything be seen at 2-3 weeks pregnant on an ultrasound?
Generally, the answer is NO. However, during weeks 3 and 4 when the gestational age (or fetal age) is 2 weeks, the earliest change that can be seen with a vaginal ultrasound is the "decidual reaction" which is the thickening of the endometrium. The endometrium lining thickens as the blastocyst burrows into it. This cannot always be detected by ultrasound-sometimes it may take a special eye or hi-resolution equipment to see this "reaction" in the endometrium lining at that very early stage. And remember that when using ultrasounds, it is the transvaginal ultrasound which can detect development in the uterus about a week earlier than a transabdominal ultrasound.
You were 16 weeks pregnant your ultrasound said that the baby size was 18 weeks which one should you do by?

Sometime around the 8th week of pregnancy is the best time to start being able to see your baby on an ultrasound.
Why is ultrasound not used to produce images of the brain?
Neurosonography is a small, specialized section of ultrasound, frequently used in the NICU on premature babies. Images of the brain are able to be produced on premature and young babies due to the skull not being fully fused together yet, therefore allowing the ultrasound beam to reach the brain tissue. Neurosonography is also used before the baby is born, and still in the mother's womb. Once the skull has fused, transcranial ultrasound is still possible to an extent, through very small openings within and around the skull. This area of ultrasound is frequently used in high risk pediatric and specialty hospitals, such as St. Jude Children's research hospital. Using ultrasound on the brain of a fully fused skull is more challenging because an ultrasound beam cannot penetrate through bone. However, with skill and knowledge, it is possible to obtain brain images.
How do doctors determine that you are expecting twins?
