The doses received by the organs in case of spinal thin-layer computed tomography, conventional tomography and myelography of the inferior lumbar spine (with first portion of the sacrum) were determined with CaF2 thermoluminescence dosemeters in the Alderson Rando phantom. As compared to computed tomography, the organ doses of the conventional examination methods were lower within the region of primary radiation and higher within the region of scattered radiation. Generally, patients examined by spinal thin-layer computed tomography of the inferior lumbar spine run a greater somatic radiation risk than those submitted to conventional examination methods.
使用CaF2热释光剂量仪在Alderson Rando人体模型中测定了下腰椎（包括第一骶椎部分）进行脊柱薄层计算机断层扫描、传统断层扫描和脊髓造影时器官所接受的剂量。与计算机断层扫描相比，传统检查方法的器官剂量在原发射线区域较低，而在散射辐射区域较高。一般来说，接受下腰椎脊柱薄层计算机断层扫描检查的患者比接受传统检查方法的患者面临更大的躯体辐射风险。
