(AUS) Abdominal ultrasound, (TAE) transabdominal echography, abdomen sonography, sonogram, (FAST) focused assessment
Ultrasonography is an ideal clinical tool for determining the source of abdominal pain. An abdominal ultrasound includes the liver, gallbladder, biliary tree, pancreas, spleen, kidneys and blood vessels of the abdomen. Conventional ultrasound is cheap, safe, non-invasive and is a practical first line investigation. High resolution ultrasound, endoscopic ultrasound and contrast enhanced Doppler techniques assist in detecting small lesions. The best preparation is nothing to eat or drink from midnight the night before the exam (minimum 8 hours).

Indications:
point abdominal pain;
point stones in the gallbladder or kidneys;
point inflammation;
point cancer, metastasis.

FAST is a rapid diagnostic test of the trauma patient that sequentially detects the presence of free fluid in pericardium (hemopericardium) and in 4 views of the abdomen. These views, the right upper quadrant (RUQ), left upper quadrant (LUQ), the subcostal, and suprapubic views detect a hemoperitoneum in patients with potential truncal injuries. The Morison pouch between the liver and right kidney (RUQ) is a space in which intraperitoneal fluid can accumulate. Emergency abdominal ultrasonography is indicated for the evaluation of aortic aneurysm, appendicitis, and biliary and renal colic, as well as blunt or penetrating abdominal trauma.

Intro, 
Historical Development,

(CEUS) Contrast agents increase the reflection of ultrasonic energy, improve the signal to noise ratio and caused by that the detection of abnormal microvascular and macrovascular disorders. Contrast enhanced ultrasound is used in abdominal ultrasound (liver sonography) as well as in cerebrovascular examinations e.g., for an accurate grading of carotid stenosis. The used contrast agents are safe and well tolerated.

The quality of the enhancement depends on:
point the concentration of the contrast agent;
point the type of injection, flow rate;
point the patient characteristics;
point the microbubble quality and properties of the filling gas and the shell.
The additional use of ultrasound contrast agents (USCAs) may overcome typical limitations like poor contrast of B-mode imaging or limited sensitivity of Doppler techniques. The development of new ultrasound applications (e.g., blood flow imaging, perfusion quantification) depends also from the development of pulse sequences for bubble specific imaging. In addition, contrast enhanced ultrasound improves the monitoring of ultrasound guided interventions like RF thermal ablation.

Convex TransducerInfoSheet: Probes/Transducers
Intro,

TransducersMRI Resource Directory:<br> - Probes Transducers -
 
Convex transducers are today standard on every new scanner. A convex surface allows the scanning of a larger area with a smaller array. The method of focusing and beam sweeping of a convex or curvilinear / curved array is similar to a linear array transducer, except of the shape of the probe and the sector format of the created image.
The better fit to the body, caused by the curved shape with smaller convex contact surface, and the wider field of view further from the transducer face are advantages in abdominal ultrasound.
However, also a convex array is often too large to image the heart when probing between the ribs. Caused by combining a large field of view with smallest array size, phased array transducers are the best choice in cardiac ultrasound.

Pediatric UltrasoundMRI Resource Directory:<br> - Pediatric -
 
Ultrasound is the ideal tool to examine children of all ages. It is fast, painless, uses no ionizing radiation, and does not require a baby to remain still for long periods. Real-time modes show movement of internal tissues and organs. Advanced ultrasound imaging techniques such as color Doppler, 4D ultrasound, harmonic imaging, and higher resolution, as well as the application of ultrasound contrast agents broaden the potential of ultrasound.
Pediatric [paediatric, Brit.] ultrasound can be used in all body regions and reduce the number of more invasive or radiating examinations that often additionally need sedation or intravenous iodinated contrast agents.

Side EffectMRI Resource Directory:<br> - Safety -
 
Diagnostic ultrasound imaging has no known risks or long-term side effects. Discomfort to the patient is very rare if the sonogram is accurately performed by using appropriate frequencies and intensity ranges. However, the application of the ALARA principle is always recommended.
There are reports of low birth weight of babies after applying more than the recommended ultrasound examinations during pregnancy. Women who think they might be pregnant should raise this issue with the doctor before undergoing an abdominal ultrasound, to avoid any harm to the fetus in the early stages of development.
Since ultrasound is energy, sensitive tissues like the reproductive organs could possibly sustain damage if vibrated to a high degree by too intense ultrasound waves. In diagnostic ultrasonic procedures, such damage would only result from improper use of the equipment.

Possible ultrasound bioeffects:
list_point Ultrasonic heating of tissues can be created by absorption of the ultrasound energy.
list_point Due to increasing of temperature, dissolved gases from microbubbles come out of the contrast solution.
The thermal effect is controlled by the displayed thermal index and the mechanical index indicates the risk of cavitation.
An ultrasound gel is applied to obtain better contact between the transducer and the skin. This has the consistency of thick mineral oil and is not associated with skin irritation or allergy.
Specific conditions for which ultrasound may be selected as a treatment may be attached with higher risks.
