helpful in the measurement of the total or individual kidney GFR (DTPA)
or effective renal plasma flow (MAG3 or Hippuran).
- Magentic Resonance Imaging (MRI)
The principle of MRI is the excitation of the nuclei of atoms such
as hydrogen in tissues with radiowaves, and detection of echo radiation
from these nuclei when the radio source is removed. Thus, the MRI
provides information at the cellular level. Currently, this recent technique
provides excellent anatomical informations (Figure 2.11) which are very
helpful in studying malignancies of the urinary tract and assessment of
renal vessels.
