It all depends on which X-ray was taken to find the kidney stones. The hospitals generally provide a CT scan, an MRI or a PET. PET is the most precise because it shows abnormalities or suspected abnormalities on tissue. Some scans are blind to bones and show only tissue, other scans are blind to tissue and show only bones. Sometimes the radiologists cannot really “read” their “plates” very well and often cannot come up with a definite explanation and they would refer to the doctors who also cannot “read” the “plates.” Small dots will often show up on a PET scan but not on a CT scan. So the doctors get all worried and may suggest immediate biopsy. (ref. my wife’s scans) However, sometimes successive scans at regular intervals will clarify a particular “suspicious spot” that the radiologists and the doctors could not “read”. The successive scans should be able to reveal whether the “suspicious spot” has grown in size, and the doctor can calculate the rate of growth and make comparisons to see if a biopsy would be needed after successive scans are taken.
Stones would show up as dots or spots while the crack of a cracked rib may not show up. Scans that show bones like the scans specifically for bone fractures should be able to show any cracks of a cracked rib.
In China, the CT scan and B-scan ultrasonography are very commonly used for echographic exams of soft tissue such as liver tumor and liver shrinkage. In some cases, a CT scan reconfirms the diagnosis of B-scan ultrasonography. However, B-scan ultrasonography cannot detect hepatitis B.
