Abstract
In order to assess the usefulness of 09mTc·DTPA
renal scan in diagnosing acute rejection renal graft,
we performed 87 studies on 26 renal graft recipients.
All the grafts except one were transplanted from
living donors. The majority of the studies were made
during the early posttransplantation period. At the
time of scanning, the retrospectively confirmed clin·
ical assessment of the graft function was normal in
75 studies, acute rejection in 10, acute tubular
necrosis in one and renal artery stenosis in the
other.
As well as data obtained from scintillation camera
images, computer-drived time-activity curves of renal
perfusion were analyzed using 4 different parameters-
aortorenal transit time. peak to plateau ratio,
perfusion index, and T1/2 of washout phase.
The perfusion curve of normal functioning kidney
showed sharp peak follow by rapid declination of
radioactivity. But the curve of acute rejection showed
low, blunted peak and delayed washout in all cases, whereas that of acute tubular necrosis was relatively
normal. Among the 4 perfusion parameters, Tl/2
revealed the highest diagnostic sensitivity (100%),
that is, it was increased over 20 sec. in all acute
rejection cases. And its specificity is 93.296.
From the above results, we concluded that cornputer-
processed 9OmTc·DTPA renal scan was useful in
diagnosing acute rejection of transplanted kidney.
