OBJECTIVE The purpose of this study was to survey the radiation dose used in CT urography (CTU) in routine clinical practice, both before and after implementation of a scanning protocol that uses iterative reconstruction (Adaptive Iterative Dose Reduction 3D [AIDR 3D]). MATERIALS AND METHODS We retrospectively surveyed dose reports from consecutive CTU examinations performed in 2011 with the use of 64- and 320-MDCT scanners that were reconstructed with filtered back projection (FBP) and from…

Impact of Low-Dose Computed Tomography on Computed Tomography Orders and Scan Length

A campaign alerting staff to the availability of low-dose CT did not cause an increase in CT examination ordering and did not impact the area scanned by technologists.

Computed tomography urography with iterative reconstruction algorithm in congenital urinary tract abnormalities in children – association of radiation dose with image quality

Low-dose CT urography can be a valuable method in congenital urinary tract abnormalities in children despite poorer image quality, diagnostic confidence is not significantly compromised in examinations performed with lower radiation doses.

CT-urography: a nationwide survey by the Italian Board of Urogenital Radiology

Italian radiologists were asked to express their opinions about computed tomography–urography performance and about its role in their daily practice through an online survey, and this paper collects and summarizes the results.

CT urography : principles and indications CT urografija : načela i indikacije

Detailed patient history, clinical examination, and urine analysis are essential for proper patient selection and targeted CTU protocol, which are the most important tools for increasing diagnostic accuracy and lowering patient radiation dose of CT urography.

Integration of CT urography improves diagnostic confidence of 68Ga-PSMA-11 PET/CT in prostate cancer patients

Integration of CTU into 68Ga-PSMA-11 PET/CT is feasible and increases diagnostic confidence of assigning focal areas of tracer accumulation in the ureteric space to either metastatic disease or ureTERic excretion.

The Harms of Hematuria Workup: Modeling the Risk-Benefit of Using Split-Bolus CT Urography to Reduce Radiation Exposure in a Theoretical Cohort.

The data indicate that SB-CTU may safely be utilized in 70% of the population of patients with MH, but is not currently advisable for GH or other high-risk patients.

What a difference a delay makes! CT urogram: a pictorial essay

Excretory phase imaging of CT urography can be an essential tool for detecting and appropriately characterizing urinary tract malignancies, renal papillary and medullary abnormalities, CT radiolucent stones, congenital abnormalities, certain chronic inflammatory conditions, and perinephric collections.

Influence of diuretic (furosemide) on contrast medium distribution in computed tomography urography of high-grade hydronephrosis in children

Addition of furosemide to computed tomography urography does not improve homogeneity of contrast medium distribution in hydronephrotic kidneys in children.

Diagnosis and Management of Upper Urinary Tract Recurrences After Radical Cystectomy

Surgical options for UUT-UC will be discussed which may include conservative approaches for elderly bladder cancer patients after urinary diversion and renal insufficiency who may tolerate neoadjuvant chemotherapy or radical nephroureterectomy.

Low-Dose Computed Tomographic Urography Using Adaptive Iterative Dose Reduction 3-Dimensional: Comparison With Routine-Dose Computed Tomography With Filtered Back Projection

Low-dose CT urography using AIDR 3D can offer diagnostic acceptability comparable with routine- dose reduction 3-dimensional with approximately 70% dose reduction.

Individualized kV Selection and Tube Current Reduction in Excretory Phase Computed Tomography Urography: Potential for Radiation Dose Reduction and the Contribution of Iterative Reconstruction to Image Quality

The combination of iterative reconstruction, automated kV selection, and tube current reduction results in radiation dose reduction with preserved image quality and diagnostic confidence.

Spatial resolution and radiation dose of a 64-MDCT scanner compared with published CT urography protocols.

Limiting anatomic coverage for specific phases and combining phases can reduce dose for multiphase protocols by up to a factor of 2 relative to early (circa 2000) 4-MDCT.

Impact of adaptive iterative dose reduction (AIDR) 3D on low-dose abdominal CT: comparison with routine-dose CT using filtered back projection

Low-dose abdominal CT using AIDR 3D allows for approximately 50% reduction in radiation dose without a degradation of image quality compared to routine-dose CT using FBP independently of BMI.

A national survey on radiation dose in CT in The Netherlands

CT in the Netherlands is associated with relatively low individual radiation doses in standard patients compared to surrounding European countries, indicating the need for further optimisation.

How much dose can be saved in three-phase CT urography? A combination of normal-dose corticomedullary phase with low-dose unenhanced and excretory phases.

With a three-phase CT urographic protocol, significant dose reductions in the unenhanced and excretory phases can be achieved when these phases are combined with a normal-dose corticomedullary phase.

Dose Reduction in Abdominal Computed Tomography: Intraindividual Comparison of Image Quality of Full-Dose Standard and Half-Dose Iterative Reconstructions With Dual-Source Computed Tomography

Direct intrapatient comparison of standard FD body protocols and HD-IRIS reconstruction suggest that the latest iterative reconstruction algorithms allow for approximately 50% dose reduction without deterioration of the high image quality necessary for confident diagnosis.

Adaptive iterative dose reduction 3D versus filtered back projection in CT: evaluation of image quality.

AIDR 3D performs better than FBP with regard to noise and LCD, resulting in better image quality, and performs similarly with respect to spatial resolution.
