Fig. 3B —40-year-old man referred for mercaptoacetyl-triglycine (MAG3)
scanning because of suspected obstruction. Expanded QuantEM review display
shows patient values for MAG3 clearance; residual urine volume; percent
relative uptake; and time to maximum (Tmax), 20-minute-to-maximum-count ratio
(20/max), half-time (T
), and postvoid to maximum count
(postvoid/max) ratios for whole-kidney and cortical ROIs as well as normal
ranges for each of these values. Expanded review page also shows enlarged
parenchymal image obtained at 2-3 minutes, enlarged display of 19- to
20-minute image, and quality control images showing preinjection and
postinjection syringe counts and time of bolus arrival in kidneys. In
particular, enlarged 2- to 3-minute image shows dilated renal pelvis, and
postvoid/max ratio for right kidney is slightly elevated.
