Interventional UltrasoundMRI Resource Directory:<br> - Ultrasound Therapy -
 
Interventional ultrasound or ultrasonography uses invasive or surgical procedures. Its widest application is intravascular ultrasound imaging, for example used to measure atherosclerotic plaque. But it is useful also in urology for prostate treatment with high intensity focused ultrasound and intraabdominal conditions like endoscopic ultrasound.
Ultrasound guided interventions, like RF thermal ablation or biopsies are used e.g., in liver sonography, obstetric and gynecologic ultrasound, or thyroid ultrasound procedures.

Breast UltrasoundMRI Resource Directory:<br> - Breast -
 
Breast ultrasound (sonography or ultrasonography) it is an important tool in the characterization of breast lesions, detected with mammography or clinical breast examination. However, a breast sonogram is not approved by the U.S. Food and Drug Administration (FDA) as a screening tool for breast cancer and is used additional to a mammogram.
Ultrasound is useful in guiding needles for fine needle aspiration and core biopsies. Breast ultrasound has optimal contrast resolution, but it lacks the spatial resolution of conventional mammography and cannot provide as much detail as a mammogram image. In addition, ultrasound is unable to show tiny calcium deposits (microcalcifications) that are often early indications of breast cancer.

Endocavitary EchographyMRI Resource Directory:<br> - Endoscopic -
 
The usual applications of endocavitary echography (also called internal echography / endoscopic ultrasound (EUS)) are examinations of the pelvic organs through internally introduced probes, which give a more precise and correct image.
Transrectal ultrasound is a well established method for rectal or prostate carcinoma assessment.
A transvaginal echography uses a small transducer that is inserted directly into the vagina.
Used are high-frequency (10-12 MHz) for superficial organs, endocavitary echography, and intraoperative laparoscopic ultrasound. A sterile cover is slipped over the probe, which is then covered with lubricating ultrasound gel and placed in the cavitary (see Equipment Preparation).

Intravascular UltrasoundMRI Resource Directory:<br> - Intravascular -
 
(IVUS) For intravascular ultrasound a small IVUS catheter with a probe is introduced into the artery. The transducer transmits and receives acoustic energy through this catheter. The reflected acoustic energy is used to build a picture of the inside of the vessel. A IVUS image consists of three layers around the lumen, the intima, media and adventitia.
In addition, elastography or palpography could be used to evaluate the local mechanical properties of tissues (e.g. lipid pools in high-risk vulnerable atherosclerotic plaques). These techniques use the deformation caused by the intraluminal pressure generated by the probe.
A high strain region at the lumen vessel wall boundary has 88% sensitivity and 89% specificity for identifying vulnerable plaques. There are high strain values of 1% in soft plaques with increased strain up to 2% at the shoulders of the plaque, while calcified material shows low strain values (0-0.2%). The radial strain in the tissue is obtained by cross-correlation techniques on the radio frequency signal. The strain is color-coded and plotted as a complimentary image to the intravascular ultrasound echogram.

Magnetic Resonance Guided Focused UltrasoundMRI Resource Directory:<br> - Ultrasound Therapy -
 
(MRgFUS) Magnetic resonance guided focused ultrasound is a surgical procedure that uses high intensity focused ultrasound waves to destroy tissue in combination with magnetic resonance imaging (MRI), which guides the treatment.
With focused ultrasound waves uterine fibroids are heated and destroyed (ablated) inside the MRI device , allowing the physician to plan, monitor and control the treatment with temperature sensitive images while it is in progress.
