Diagnosis of the Presence of Stones
The identification of the gall stone becomes very simple by the plain abdominal film which is to be containing a sufficient amount of the calcium so that there is proper radio opacity.
This type of the radiographic technique can be very helpful in the identification of the emphysematous cholecystites that is the inflammation of the gall bladder and is usually caused commonly by the obstruction of the outlet of the contents of the gall bladder outside into the alimentary canal which may be acute or chronic
This is usually accompanied by a type of bacterial infection, limey bile or milky bile which is the precipitation of the salts of calcium in the lumen of the gall bladder and hence causing the obscure opacification of the bile or a type of roentgenography that is plain in the abdomen, then there is the porcelain gall bladder which means the deposition of the salts of the calcium into the wall of the gall bladder facing a chronic affections and inflammations also detected by the help of the plain abdominal film technique.
The most common process in the diagnosis of the gall stones have been the Ultra Sonography. By this technique the visibility of the gall stones are very clear and images of it can also be procured. Through this method only those gall stones can be identified very easily that have a diameter of about 2 mm.
The OCG or the Oral Cholecystography is a very important and an advanced useful technique that has been successfully been used in the detection and the diagnosis of the stones of the gall bladder. It has been found that this method of investifga5tions have been replacing the more customary ones of the Ultra Sonography. There are some other methods involving the radiopharmaceuticals for the detection of the gall stones that are used in some cases.
