DURING the investigation of abdominal masses by pulsed ultrasound (Donald et al., 1958) it was found that a foetus could be visualized as early as fourteen weeks. This had been found more or less by accident when examining a case thought clinically to have uterine enlargement due to fibromyomata. examination. We have since explored the earliest period of gestation at which foetal echoes can be made out. We also wished to determine if sonar examination would assist in the diagnosis of certain… 

Ultrasound. An aid in the diagnosis of ectopic pregnancy.

Ultrasonics in obstetrics and gynaecology.

Sonar is easy to apply as a diagnostic method in obstetrics and gynaecology by direct contact scanning through a film of olive oil applied to the abdominal wall and the estimation of retained products of conception following abortion are now commonplace.

Clinical management of patients: the gynaecologist's perspective

Transvaginal ultrasonography was first described in 1969, but it was only after its evaluation of infertility in the 1980s that its full potential was realised and it is now also used in the investigation and management of infertility and assisted reproduction, early pregnancy, tubal pregnancy and first-trimester pregnancy-related conditions.

THE DIAGNOSIS OF EARLY PREGNANCY FAILURE BY SONAR

  • H. Robinson

    British journal of obstetrics and gynaecology
  • 1975
On analysis of the sonar and post‐abortion findings it was found that the aborted pregnancies fell into five clearly defined groups; blighted ova or anembryonic pregnancies, missed abortions, hydatidiform moles and early and late live abortions.

  • 1967
Interest in amniography has been revived, due largely to the safety of amniocentesis reported by numerous workers in the management of rhesus isoimmunization and the development of better radioopaque substances has also contributed to its revival.

Diagnostic Use of Ultrasonics in Abortion

  • 1973
Diagnostic ultrasound, two dimensional echography, and Doppler fetal heart detection were used in 250 patients with clinical symptoms or medical history of threatened abortion to demonstrate the growth of the gestation sac and fetus, placental retention, and whether the uterus is empty.

Hydatidiform Mole with Coexistent Fœtus

  • J. Bruce
  • Medicine
    Proceedings of the Royal Society of Medicine
  • 1972
The patient was 22 weeks pregnant with certain dates and no family history of twins, and because the uterus was 'larger-than-dates', with palpable foetal parts and excess liquor, a diagnosis of severe rhesus disease possibly associated with twins was made.

Sound waves of a pitch approximately one hundred times the upper limit of audibility may be used for medical diagnosis and cross-sectional pictures of the tissue structures may be formed.

Demonstration of tissue interfaces within the body by ultrasonic echo sounding.

The principle of this ultrasonic echo sounding technique is applied to reveal the boundaries between the different tissue structures within the body to provide scope for enlarging the field of diagnostic radiology.
