These patients will be included on the basis of suspicion of or proven pregnancy of duration up to 12 weeks from LMP.
The evaluation of the patients will include the following: Record of patients obstetrical history and clinical examination, record of pregnancy test and relevant investigations, ultrasonic examination of pregnancy. Relevant images will be taken by using the multiformat automatic camera. In the study of 46 normal intrauterine pregnancies, TVS showed additional information in 36 patients The other advantages of TVS over TAS are that there is no need for the patient to have uncomfortably full bladder and time is saved from having to wait for bladder to fill.
Thus, the potential preoperative patient can be kept fasting. TVS is also superior in obese patients, in patients with retroverted uterus and it also bypasses obstacles such as bone, gas filled bowel, and extensive pelvic adhesions. The limitations encountered with TVS were limited manoveuribility of probe and because of the unorthodox position and angle of the transducer, correct orientation was difficult initially.
Ultrasound: Sonogram - American Pregnancy Association
Comparison, first trimester of pregnancy, transvaginal ultrasonography, various fetal development markers Ultrasonography is one of the most important and useful diagnostic tool in the field of modern medicine.
Being noninvasive, safe and without hazards of radiation, it has gained wide acceptability, as an integral part of basic investigative procedures. The convenience, high portability, rapidity, and accuracy are few of the advantages of ultrasound over the other procedures. In the last two decades, ultrasound has become an essential diagnostic imaging modality in the field of obstetrics and is being extensively used for evaluation of pregnancy.
Obstetrical ultrasound enables the clinician to evaluate the development, growth, and well being of the fetus. The ability to study the fetus in the intrauterine environment has been notably enhanced by dramatic improvement in imaging. Although static scan imaging may compliment ultrasound studies, obstetrical examination should always be accompanied by real time modalities. In the standard transabodominal ultrasonography lower frequencies with poorer axial resolution ability to distinguish two separate points in the direct line of the ultrasound beam are being used to image structures deeper in the body such as pelvic organs.

The recent development of higher frequency 5 and 7. Transabdominal scanning is used predominantly in second and third trimesters of gestation. Its use in first trimester is relatively limited and mostly diagnostic in nature. The introduction of the higher frequency transvaginal probe, with its higher resolution of images, opens new possibilities to study early gestation Timor Tritsch. There was an exponential correlation between the mean gestational sac diameter and gestational sac volume and the crown-rump length and embryonic volume in cases of both normal and failed pregnancies.
Lazarus E[ 3 ] - what is new in first trimester ultrasound. He commented that there are several advantages to ultrasound examination in early pregnancy.
Ultrasound performed during the first trimester confirms an intrauterine pregnancy, establishes accurate dating, and is crucial in diagnosing early pregnancy failure and ectopic pregnancy. My husband later remarked that I had a very serious look on my face.Transverse Transabdominal US uterus
The midwife took over for the student and still more silence. My supportive midwife encouraged me and said that many women do not hear the heartbeat at ten weeks and to try again the following week.
The next week, at eleven weeks and four days gestation, I stopped in again for a heart tone check. I climbed back up on the examining table and she went to work.

Taking Matters In Our Own Hands She then told me that she could manually move my uterus forwards via a vaginal exam which would put my baby closer to the doppler. I agreed and we began. It was a faint sound, but I definitely heard a strong rhythmic beats per minute.
I was so overwhelmed and happy! However, at eleven, almost twelve weeks gestation my uterus obviously had not done that. W hen I was fifteen weeks pregnant I started feeling these stretching, full, stabbing pains in my uterus. This lasted a short while, and then it stopped.
At sixteen weeks gestation I had my second prenatal visit and the handheld doppler was again used to listen to heart tones.
