abstract

  • Numeric angiography possesses the definite advantages of diminished risks when compared with conventional arteriography, and marked reliability when used for valid indications. It is also economically interesting since hospitalization is avoided. Limitations of the method are currently related to technical and data-processing problems. Insufficient size of the brilliance amplifiers means that several injections of contrast medium are necessary, with increased risks in some patients. Image resolution is insufficient with currently available matrices to study small vessels. The rate of image production, originally insufficient, now with modern equipment enables mobile structures such as the heart to be studied.
