Sonography of the gallbladder is a reliable technique for diagnosing e.g., gallstones, cholecystitis, tumors, polyps, or ductal obstruction. Patient should be examined with empty stomach and on a low fat diet the night before. Barium studies, endoscopy, ERCP, colonoscopy, and abdominal CT should be performed after this examination.
Gallbladder ultrasound is best performed with a 5 MHz curved array or a linear array transducer in cases of a very superficial gallbladder. In obese patients or in patients with difficult sonographic access, a 3.5 MHz sector or curved linear transducer is advantageous.
Gallbladder and biliary tree are usually imaged in supine and posterior oblique (LPO) positions. Sometimes very small gallstones are better visible in upright and prone position.

Cardiac ultrasound, also known as echocardiography or echocardiogram, is used to provide several different levels and types of heart testing. Cardiac ultrasound utilizes the same ultrasound principles as used for obstetric and gynecologic evaluations of pregnant women, gallbladder ultrasound and other abdominal structures.
The ultrasound is directed out of a hand held probe which can be moved to image the heart from different positions. Additionally, so that heart events can be timed, ECG leads are placed on the chest. The reflected wave is converted into an actual image of the heart and displayed in a real-time mode or M-mode ultrasound format. M-mode recordings permit measurement of cardiac dimensions and detailed analysis of complex motion patterns depending on transducer angulations. Also the time relationships with other physiological variables such as ECG, heart sounds, and pulse tracings, can be recorded simultaneously. A stress echocardiogram provides information about the cardiac performance.
Two-dimensional tomographic images of selected cardiac sections give more information than M-mode about the shape of the heart and also show the spatial relationships of its structures during the cardiac cycle (diastole to systole).

(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.

Liver SonographyMRI Resource Directory:<br> - Liver -
 
A liver sonography is a diagnostic tool to image the liver and adjoining upper abdominal organs such as the gallbladder, spleen, and pancreas. Deeper structures such as liver and pancreas are imaged at a lower frequency 1-6 MHz with lower axial and lateral resolution but greater penetration. The diagnostic capabilities in this area can be limited by gas in the bowel scattering the sound waves.
The application of microbubbles may be useful for detection of liver lesions and for lesion characterization. Some microbubbles have a liver-specific post vascular phase where they appear to be taken up by the reticuloendothelial system (RES). Dynamic contrast enhanced scans in a similar way as with CT or MRI can be used to studying the arterial, venous and tissue phase.
After a bolus injection, early vascular enhancement is seen at around 30sec in arterialized lesions (e.g., hepatocellular carcinomas (HCC), focal nodular hyperplasia (FNH)). Later enhancement is typical of hemangiomas with gradually filling towards the center. In the late phase at around 90sec, HCCs appear as defects against the liver background. Most metastases are relatively hypovascular and so do not show much enhancement and are seen as signal voids in the different phases.
Either with an intermittent imaging technique or by continuous scanning in a nondestructive, low power mode, characteristic time patterns can be used to differentiate lesions.

Medical Sonography (also called ultrasonography) uses equipment that generates high frequency sound waves to produce images from muscles, soft tissues, fluid collections, and vascular structures of the human body. Obstetric sonography is commonly used during pregnancy. Sonography visualizes anatomy, function, and pathology of for example gallbladder, kidneys, pancreas, spleen, liver, uterus, ovaries, urinary bladder, eye, thyroid, breast, aorta, veins and arteries in the extremities, carotid arteries in the neck, as well as the heart.
A typical medical ultrasound machine, usually a real-time scanner, operates in the frequency range of 2 to 13 megahertz.
