Re: Diagnosing Stones

Yet another in many websites that can detect cholesterol stones and very descriptive on this is done. it seems that cholesterol stones are quite easy to detect!

"Cholesterol stones usually have an attenuation value that is lower than bile and are visible on CT as hypoattenuating structures. The "Mercedes-Benz" sign is a triradiate central fissure of the stone and is particularly well displayed on CT as a hypoattenuating triradiate figure. MRI (Fig.4) and MRCP are able to visualize Gallstones reliably"

and from another site:

Discussion

It is evident from this study that cholesterol Gallstones do not exhibit a uniform sonographic appearance, but have a variety of distinct patterns. The traditional description of a gallstone is that of an echogenic focus with posterior acoustic shadowing [2,3]. The character of the shadowing helps us categorize cholesterol stones into distinct sub-types. Tsuchiya et al [7] described three sub-types of sonographic morphology (namely comet, half moon and crescent). Other workers have described two additional sonographic patterns, namely sonolucent and irregular [8,9]. The description of these patterns is akin to our classification of full moon and others, respectively.
