Results
According to the study mean perfusion CT parameter values (BV,
Clearance and BF or BF,
BV,
MTT and PS) for normal renal cortex and the renal tumors are summarized in Table 1 for the first group and in Table 2 for the second group.
Significant differences between RCC and normal renal cortex in all investigated parameters were found in both groups (P=0.001) Fig.
4-5.
Deconvolution is more simple method of postprocessing,
it takes about 5 minutes.
Patlak plotting is operator depending and very sensitive to image noise.
The estimated effective radiation dose of the protocol used in the second group was controlled to within 22.9 mSv,
which is above the effective radiation dose used for the first group (4,5+-1,2 mSv).To reduce the effective dose,
we reduced the tubecurrent time product depending on the weightof patients.
