Low-dose CT of the lungs: Preliminary observations

摘要: The potential of low-dose computed tomography (CT) the lungs was critically evaluated in two patients with normal-appearing and 10 a wide diversity underlying parenchymal abnormalities. At each five levels, addition to routine scans obtained at 120 kVp 140 mA, scan mA half were obtained, all other parameters held constant. Each visually assess anatomic clarity as well presence artifacts extent graininess. levels thorax, visualization structures not affected by decreasing milliamperage. It appears that high-quality, diagnostic images lung can be very low radiation dose. Although further evaluation is necessary, CT for use pediatric population particular, screening high risk developing cancer, apparent.
