[The oblique projection in lung perfusion scintigraphy (author's transl)].

In perfusion lung imaging by scintillation camera routine use of posterior oblique views is recommended in addition to anterior and posterior views. Avoiding overlap activity ("shine through") from the contralateral lung they improve the detection rate as well as the characterisation and localisation of perfusion defects especially in the lower lobes. Artifacts due to increased absorption in the scapular region or to compression by mediastinal structures should be recognized.
