[Determination of the count rate for quality control of combined lung ventilation and perfusion scintigraphy: case report].
We present the case of a 43-year-old male patient who suffered from a massive pulmonary embolism, induced by a peritoneovenous shunt of the Denver type. Calculation of the count rates of the ventilation and perfusion scintigraphy respectively showed a too low ventilation/perfusion ratio. After reinjection of additional 99mTc-MAA the second perfusion study showed further mismatch areals. Count rate ratio determination is essential as a clinical quality control.
