Ultrasound Imaging ProceduresMRI Resource Directory:<br> - Patient Information -
 
Ultrasound imaging procedures are widely used in medicine. It is possible to perform diagnostic or therapeutic procedures with the guidance of ultrasonography (interventional ultrasound biopsies or drainage of fluid collections). Sonography or ultrasound scanning involves the application of an ultrasound transducer used to transmit high frequency sound waves, which bounce off internal structures to produce an image that can be displayed and recorded.
Ultrasound imaging procedures include for example:
point A-scan;
point B-scan;
point echocardiography;
point Doppler ultrasound;
point interventional ultrasound (e.g., endoscopic ultrasound);
point ultrasound treatment (e.g., high intensity focused ultrasound).

ReductionMRI Resource Directory:<br> - Artifacts -
 
An image artifact is any image attribute, which is not present in the original imaged object. An image artifact is sometime the result of an improper operation of the imager, and in other times a consequence of natural processes or properties of the human body.
Artifacts in diagnostic ultrasound are a reflection or an echo, which appears on the display and represents the real anatomical structure not correctly. An artifact can be a false, multiple or misleading information introduced by the imaging system or by interaction of ultrasound with the adjacent tissue.

Artifacts in ultrasound can be classified as to their source like e.g.:
point physiologic (motion, different sound velocities, acoustical impedances of tissue);
point hardware (dimension of the ultrasound beam and the transducer array);
point imaging technique (B-mode, spectral Doppler, color Doppler, 3D ultrasound).
Image artifacts can occur in each medical ultrasound. Then an interpretation of the image is complicated and can eliminate the structural information of objects looking for.

B-ScanMRI Resource Directory:<br> - Modes -
 
B-scan ultrasonography, or B-scan, is a diagnostic test, for example used in ophthalmology to produce a two-dimensional, cross-sectional view of the eye and the orbit. The presentation of the reflected pulses are displayed in rectangular coordinates, in which the travel time of an ultrasound pulse is represented as a shift along one axis, and the probe movement is represented as a shift along the other axis.

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.

Ultrasound BiomicroscopyMRI Resource Directory:<br> - UltraSound Physics -
 
Ultrasound biomicroscopy utilizes high frequency (10 - 50 MHz) diagnostic ultrasound to examine living tissue at a microscopic level and allows to image the skin with extremely high resolution to a depth of 2-3 centimeters. Ultrasound biomicroscopy images provide detailed anatomical information that can lead to better and more accurate treatments and avoid a biopsy.
Ultrasound biomicroscopy improves also the spatial resolution of US images of the anterior segment of the eye. US biomicroscopy of the eye operates in the 50 MHz range with a possible axial resolution on the order of 30 µm. In this frequency range, tissue penetration of only approximately 5 mm is attainable. Both continuous wave Doppler and high-frequency pulsed Doppler can be used.
