Quantitative investigation of the x-ray absorption coefficient in computed tomography. An approach to numerical diagnosis.

abstract：:"Congenital" tumors that cause hydrocephalus early in life are large masses and can easily be detected by ultrasound. CT is better for differentiating among the diverse types of mass lesions and is performed after screening by ultrasound. In our experience, ultrasound has proved successful for visualizing all of the i...
