Low-dose computed tomography of the paranasal sinus and facial skull using a high-pitch dual-source system—First clinical results

Abstract

Using the proposed dual-source mode when examining the paranasal sinus, diagnostic image quality can be achieved while drastically lowering the patient's radiation exposure.

Imaging the Parasinus Region with a Third-Generation Dual-Source CT and the Effect of Tin Filtration on Image Quality and Radiation Dose

“…The same group published data of a patient cohort comparing conventional mode and HPM and stated that the effective dose may be reduced by half by using HPM, with a mean effective dose of 0.11 mSv. 21 Aksoy et al 22 compared conventional mode and HPM on a second-generation dual-source CT scanner and considered HPM with a tube current of 18 mAs at 80 kV sufficient to rule out sinus disease. The estimated effective dose was reported to be 0.02 mSv.…”

An education and training programme for radiological institutes: impact on the reduction of the CT radiation dose

“…At the same time, radiologists and medical physicists have published many scientific manuscripts regarding low-dose CT protocols and general dose reduction strategies [7][8][9][10][11][12][13][14][15]. However, the various techniques and strategies for dose reduction are only effective if they are applied correctly.…”

Radiation Dose Reduction in Paranasal Sinus CT Using Model-Based Iterative Reconstruction

“…[3][4][5][6][7][8][9][10][11][12][13] Recently, high-pitch dual source multidetector CT systems have shown promise of even greater dose reduction. 14,15 Nevertheless, because of progressively decreasing signal-to-noise, a threshold for tube output is invariably reached, below which imaging becomes unacceptable.…”
