Currently available investigating modalities like CT scans, MRI etc although have a high accuracy in staging of gastrointestinal(GI) tract malignancies, are not correct in all cases . The aim of this study is to assess the role of intraoperative ultrasound as a modality to increase the staging accuracy of GI tract malignancies

Patients with Morton neuroma of the foot will undergo either ultrasonography or MRI. The results will be compared. In case of surgery, the pathology report will be compared with the ultra...
Ultrasonography has become a critical ancillary test in the clinical practice of ophthalmology. It is commonly used as a standardized method for assessing intraocular biometry. The PalmSca...
In this study, the investigators will investigate how patients' radial artery diameters change according to sex, age, height, weight and body mass index by measuring radial artery diameter...
There are several ways to verify the correct positioning of a gastric tube. Radiography is considered the reference method. The use of ultrasonography could diminish the number of radiogra...
Ultrasonography (US) is an operator depended image modality that is difficult to reproduce and interpret by others. Competence of the US operator is crucial for reliable diagnostics but no...
M-mode ultrasonography might be useful for detecting hemidiaphragm paralysis. The objective of the present study was to describe the motion recorded by M-mode ultrasonography of both diaphragmatic lea...
Point-of-care ultrasonography (POCUS) has recently become a useful tool that intensivists are incorporating into clinical practice. However, the incorporation of ultrasonography in critical care in de...
The aim of this study was to evaluate whether the comet tail artifact on ultrasonography can be used to reliably diagnose benign gallbladder diseases.
The diagnostic capacity of ultrasonography (US) for differentiating between malignant and benign thyroid nodules is crucial in preventing unnecessary invasive procedures. This is the first study to ev...
Ultrasonography is highly sensitive for the diagnosis of sialoliths. Recently, wireless mobile ultrasonography was developed. We describe the case of a 49-year-old man who presented with painful postp...
Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.
Ultrasonography applying the Doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return.
Ultrasonography applying the Doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the Doppler shift frequency.
Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow.

Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
