Simulated angiographic examinations of the cerebral arteries for various diagnostic purposes were carried out. Radiation exposure was compared between DSA and a conventional cut film technique in two planes. For most radio-sensitive structures in the head and neck, and particularly for the orbits, there was marked dose reduction for DSA, although additional projections were possible because of the reduced amounts of contrast. The cut film technique produced lower doses for the cervical marrow, cerebellum and parotid gland. All measured values were well below the critical dose so that, even with repeated examinations, no radiation damage is to be expected.
为了各种诊断目的，对脑动脉进行了模拟血管造影检查。在两个平面上比较了数字减影血管造影（DSA）和传统断层摄影技术之间的辐射暴露情况。对于头颈部大多数对辐射敏感的结构，尤其是眼眶，DSA的剂量明显降低，尽管由于造影剂用量减少可以进行额外的投照。断层摄影技术对颈髓、小脑和腮腺产生的剂量较低。所有测量值均远低于临界剂量，因此即使重复检查，也预计不会有辐射损伤。
