Before the exam, the person will need to drink three glasses of water (about 500 ml) at least one hour before the exam. If the person is on fluid restriction diet (due to heart, liver or kidney problems), then he can ignore the instruction. If there is a urinary catheter, the catheter should be clamped immediately after drinking the water. The ...
The machine used is called an ultrasound machine, a sonograph or an echograph. The visual image formed using this technique is called an ultrasonogram, a sonogram or an echogram. Ultrasound of carotid artery. Ultrasound is composed of sound waves with frequencies greater than 20,000 Hz, which is the approximate upper threshold of human hearing. [1]
Because water is an excellent conductor for ultrasound waves, visualizing these structures often requires a well-filled urinary bladder (this means the patients has to drink plenty of water before the examination). The liver can be imaged by swiping the probe sagittally from medial to lateral at the subcoastal region.
Ultrasound computer tomography (USCT), sometimes also Ultrasound computed tomography, Ultrasound computerized tomography [1] or just Ultrasound tomography, [2] is a form of medical ultrasound tomography utilizing ultrasound waves as physical phenomenon for imaging. It is mostly in use for soft tissue medical imaging, especially breast imaging ...

The body is 73% water, and therefore, acoustically homogeneous. Blood and surrounding tissues have similar echogenicities, so it is also difficult to clearly discern the degree of blood flow, perfusion, or the interface between the tissue and blood using traditional ultrasound. [4] Ultrasound imaging allows real-time evaluation of blood flow. [29]
Home ultrasound is the provision of therapeutic ultrasound via the use of a portable or home ultrasound machine. This method of medical ultrasound therapy can be used for various types of pain relief and physical therapy. In physics, the term "ultrasound" [1] applies to all acoustic energy with a frequency above the audible range of human ...
1990 - CKDu first reported in Sri Lanka's dry zones. [3] 2009 - Sri Lanka's Ministry of Health and The World Health Organization conducted a study to determine the etiology of CKDu [1] with the goal of developing preventative strategies. [7] 2016 - A case definition for CKDu was developed and published by Sri Lanka's Ministry of Health to help ...
