Detection of adrenal tumors by computerized tomographic scan in endocrine hypertension
mems used previo~nly, such as B photon absorptiom which-providrs only a paramew equivalini to TA, failed to reveal increases in bone miner?: conk nt in renal osteodystrophy even when signs of orteosclerosis were present. Thus, gamma-ray CT helps ‘G document objectively the degree of osteosclerasis and its location.
