Low Dose CT

Scan was performed without anaesthesia in a vacuum mattress with low pitch and rotation time of 1 second. Read more

We evaluated a new, subsecond high-pitch scan mode (HPM), which obviates the need of sedation and to hold the breath. Read more

We sought to evaluate the diagnostic accuracy of a new prospectively electrocardiogram (ECG)-triggered high-pitch scan mode for coronary CTA, which allows an effective dose of less than 1 mSv. Read more

To retrospectively evaluate radiation dose, image quality, and the ability to differentiate urinary calculi of differing compositions by using low-dose dual-energy CT. Read more

To compare dose and image quality of 64-slice, first and second generation dual-energy CT (DECT) for CT pulmonary angiography (CTPA). Read more

Coronary CTA using 100 kV tube potential and the FLASH spiral acquisition mode allowed ruling out coronary artery disease in this normal-sized adult patient with a DLP of 49 in only 0.29 s scan time without the use of beta blockers. Read more

To compare the diagnostic accuracy and radiation doses of two low-dose protocols for coronary artery imaging with second-generation DSCT in comparison with catheter angiography. Read more

At sub-second, low radiation dose CTA of the chest, use of individualized, patient-based contrast media delivery protocols results in reliable, diagnostic contrast enhancement of all target vessels. Read more

Objective CT of the paranasal sinus is the standard diagnostic tool for a wide range of indications in mostly younger patients. This study aims to assess the image quality of CT of the sinus by using a high-pitch dual-source technique with special regard to the radiation dose. Methods Examinations were performed … Read more
