Radiation Dose Reduction by using low dose CT protocol of thorax
The aim of this work was to compare the patient doses between two different CT protocols of thorax in patients with lymphoproliferative diseases. The entrance surface doses were measured and compared using standard CT protocol of thorax. 60 patients underwent two different CT thorax protocols during regular follow up of the disease. The doses were measured using LiF:Mg, Ti (TLD-100) thermoluminescent (TL) and GD-352M radiophotoluminescent (RPL) dosimeters on the thyroid, eye lens, sternum and gonads. The results showed that low dose protocol yielded with the reduction of doses by the factor of 1.8-15 on the eye lens, 1.0-9.1 on the thyroid, 2.5-7.0 on sternum and 0.3-12.8 on gonads, respectively. The doses were significantly lower using low dose CT protocol while the image quality for lymph node presentation was satisfactory according to European criteria. Therefore the use of low dose CT protocol as a standard for patients with lymphoproliferative disorders is highly recommended.
