## What is Sonography Ultrasound?
Sonography, also known as ultrasound imaging, is a medical imaging technology used to create pictures of organs, tissues, and other structures within the human body. This technology is commonly used to investigate the cause of medical problems such as pain or infection, diagnose conditions, and monitor the development of a fetus in early pregnancy. Unlike X-rays, sonography does not use harmful radiation, making it a safer form of imaging.
Unlike X-ray and CT scans, sonography is non-invasive and does not require a laboratory or the aid of a specialist. It uses sound waves to create a detailed image of organs and tissues without penetrating the body’s skin. This is why sonography is considered to be a much safer form of imaging compared to other diagnostic imaging techniques.
## Overview of Sonography Ultrasound
The origins of sonography can be traced back to World War II when it was used to detect submarines using sound waves that could pass through water. In the early 1950s, medical researchers adapted this technology in order to create a more accurate form of medical imaging.
The basic principle behind sonography is quite simple. As sound waves pass through human tissue, like a pregnant woman’s uterus, certain frequencies of sound are absorbed while others are reflected. The sound waves reverberate off the surface of organs and other structures, creating an image for the sonographer to interpret. The image generated by the sound waves is called a sonogram, which is a 2-dimensional picture that can show the size, shape, and position of different structures within the body.
## Benefits and Expected Results
Using sonography, physicians can gain a better understanding of the structure, shape, and size of organs, as well as detect any abnormalities or diseases. Sonography is typically used to diagnose conditions that are not readily visible with just physical examinations or X-rays. The modality is also used to evaluate pregnancies or to assess the condition of a fetus during the early stages of development.
Moreover, sonography is relatively inexpensive compared to other forms of medical imaging, requires no special preparation, and can be done quickly. In addition, sonography is a safer imaging modality compared to X-rays, which use radiation. This makes sonography an ideal choice for pregnant women or other patients who may be sensitive to radiation.
Expected results from a sonography test vary depending on the type of test being done and the condition being investigated. In general, most diagnoses made through sonography can offer immediate feedback, with results made available either during the imaging session or shortly afterwards.
## Case Studies
Sonography has been used to diagnose and monitor many different conditions. Below are two examples of how sonography has been used to diagnose and manage different conditions.
### Follicular Cyst
A 27-year-old woman was referred to a gynaecologist for evaluation of a 5cm pre-ovulatory follicular cyst on the left ovary. The patient underwent a sonography study, which revealed a large, complex-appearing cystic lesion containing macrovesicular cysts, suspicious areas of necrosis, and some edematous masses in the left adnexa. The patient was referred for a laparoscopic cystectomy to remove the cyst and was discharged the same day.
### Uterine Fibroids
A 30-year-old patient was referred to a gynaecologist to evaluate for uterine fibroids. A sonography study revealed multiple small to medium-sized fibroids scattered throughout the uterus, ranging in size from 6-7 cm in size. The patient underwent a laparoscopic myomectomy to remove the fibroids and was discharged the same day.
## Practical Tips and First Hand Experience
When undergoing a sonography procedure, it is important to be comfortable and follow the instructions given by the sonographer. If performed correctly, sonography can provide a comprehensive visualization of the anatomy. Here are some general tips for patients undergoing sonography:
– Dress appropriately for the exam, avoiding clothing with metal or jewelry.
– Ask plenty of questions and voice any concerns you may have.
– Discuss any medications or supplements that you are taking with the sonographer.
– Relax and stay calm during the exam.
From personal experience, I can attest to the accuracy and convenience of sonography. During my last pregnancy, I underwent multiple sonography exams to monitor the development of my baby and to help detect any potential anomalies. Each of the scans provided me with detailed information about my baby’s growth and development, and I was able to visualize the anatomy clearly. The ultrasound provided reassurance that the pregnancy was progressing as expected, with no visible risks or issues.

Définition et aperçu
Sonography ultrasound, or ultrasonography, is a diagnostic imaging procedure that uses ultrasound waves to visualize different structures inside the body. Ultrasound, a sound pressure wave that oscillates with a higher frequency than what people can normally hear, can measure distance and detect objects. In sonography, ultrasound waves are used to look into the patient’s body and evaluate parts such as blood vessels, joints, tendons, internal organs, and muscles.
Ultrasound is popular as an imaging and examination tool for pregnant women. This procedure is known as obstetric sonography, where ultrasound waves are used to produce real-time images of the foetus inside the patient’s womb. In many countries, obstetric ultrasound is a part of standard prenatal care.
L'échographie échographique est également très utile pour diagnostiquer et intervenir avec une grande variété de dysfonctionnements, d'irrégularités et de problèmes dans le corps. Les sonogrammes peuvent être bidimensionnels ou tridimensionnels et peuvent afficher le flux sanguin dans les veines et les artères, le mouvement des tissus sur une certaine période, la localisation des caillots, la présence ou l'absence de certaines substances dans le corps, la raideur ou d'autres problèmes avec les tissus mous et la structure des organes.
La recherche montre que l'échographie présente quelques avantages par rapport à d'autres types de procédures d'imagerie médicale. D'une part, les images échographiques sont affichées en temps réel, par rapport à d'autres techniques d'imagerie médicale qui ne prennent que des images à un certain moment, les images étant analysées après leur traitement. Les appareils à ultrasons sont également portables et peuvent être apportés directement au patient ; ceci est particulièrement utile lorsque le patient ne peut pas être physiquement déplacé vers un emplacement où se trouve un appareil à ultrasons. Plus important encore, il ne contient pas de rayonnement, ce qui le rend très sûr pour les femmes enceintes ou les patients très faibles.
Qui devrait subir et résultats attendus
La plupart des profanes associent l'échographie à la grossesse, car elle fait partie des soins prénataux standard dans de nombreux pays du monde. L'échographie peut en effet être très utile pour fournir des informations sur la santé de la mère et l'évolution de sa grossesse, ainsi que pour améliorer la précision du chronométrage du travail car le médecin peut voir les images du fœtus au fur et à mesure de sa croissance. Il réduit également le risque de travail induit.
Ultrasound procedures also provide a paediatrician or such specialists with a real-time image of the infant’s brain. Infants are quite delicate and cannot withstand other forms of medical imaging, nor could they follow instructions required by other imaging procedures. Sonography ultrasound can be performed to investigate and diagnose conditions in the eyes, thyroid, bladder, gallbladder, spleen, kidneys, pancreas, testicles, liver, blood vessels, and uterus.
Les procédures d'échographie peuvent également être effectuées pendant qu'un chirurgien effectue une biopsie pour surveiller et guider la précision et la sécurité des mouvements.
Comment fonctionne la procédure ?
Avant une échographie, le patient sera invité à se déshabiller et à se changer en chemise d'hôpital. Le patient sera ensuite invité à s'allonger sur une table d'examen pour la procédure.
Un échographiste, technicien en échographie spécialement formé, appliquera un gel lubrifiant sur la zone ciblée. Ce gel réduira la quantité de friction entre la peau du patient et le transducteur à ultrasons, qui est un appareil semblable à un microphone qui délivre les ondes ultrasonores dans la peau. Le gel est également spécialement formulé pour mieux transmettre et amplifier les ondes.
Les ondes ultrasonores feront écho dès qu'elles rencontreront un os ou un organe à l'intérieur du corps, et les échos seront retransmis dans l'unité informatique attachée.
Le patient peut être invité à changer de position de temps à autre pour analyser différentes parties du corps. Une procédure d'échographie prend généralement environ une demi-heure, le patient étant parfaitement capable de reprendre ses activités normales après la procédure.
Complications et risques possibles
L'échographie échographique est généralement sans danger, sans effets secondaires notables ou graves. C'est la raison pour laquelle les femmes enceintes peuvent subir la procédure en toute sécurité. Dans une étude publiée en 1998, l'Organisation mondiale de la santé a rapporté que les ultrasons sont inoffensifs, sûrs, efficaces et très flexibles dans la fourniture «d'informations cliniquement pertinentes sur la plupart des parties du corps de manière rapide et rentable».
