[Material selective imaging and determination of density using the dual energy method. II. Clinical use of dual energy radiography].
The use of dual energy methods in digital radiography allows selective imaging of soft tissues or calcified structures and contrast media. The value of this method is demonstrated on the basis of 400 patient examinations. The isolated imaging of soft tissues without skeletal superposition gives particular advantages in diagnosis of the chest and the cranio-cervical region. Soft tissue calcifications and calcium-containing concrements in the bile ducts and in the urinary tract are well demonstrated without soft tissue superposition. The disadvantages and the limits of the method are discussed, its potential and possible future developments are shown.
