To prospectively evaluate image quality (IQ) and radiation dose of dual-source cardiac computed tomography (CCTA) using different imaging protocols.
Methods
CCTA was performed in 150 patients using the retrospective ECG-gated spiral technique (rECG) the prospective ECG-gated technique (pECG), or the prospective ECG-gated technique with systolic imaging and automated tube voltage selection (pECGsys). IQ was rated using a 16-segment coronary artery model. Techniques were compared for overall IQ, IQ of the large and the small coronary artery segments. Effective dose was used for comparison of radiation dose.
Results
Overall IQ and IQ of the large segments showed no differences between the groups. IQ analysis of the small segments showed lowered IQ in pECGsys compared to rECG (
p
= 0.02), but not to pECG (
p
= 0.6). Effective dose did not differ significantly between rECG and pECG (
p
= 0.13), but was significantly lower for pECGsys (

To prospectively evaluate image quality (IQ) and radiation dose of dual-source cardiac computed tomography (CCTA) using different imaging protocols.

CCTA was performed in 150 patients using the retrospective ECG-gated spiral technique (rECG) the prospective ECG-gated technique (pECG), or the prospective ECG-gated technique with systolic imaging and automated tube voltage selection (pECGsys). IQ was rated using a 16-segment coronary artery model. Techniques were compared for overall IQ, IQ of the large and the small coronary artery segments.

Overall IQ and IQ of the large segments showed no differences between the groups. IQ analysis of the small segments showed lowered IQ in pECGsys compared to rECG (

p

p
< 0.001 vs. rECG and pECG).
Conclusion
Radiation dose of dual-source CCTA in heart transplant recipients is significantly reduced by using prospective systolic scanning and automated tube voltage selection, while overall IQ and IQ of the large coronary segments are maintained. IQ appears to be lower compared to retrospective techniques with regard to small coronary segments.
Key points
•
Cardiac computed tomography angiography is useful for cardiac allograft vasculopathy assessment.
•
Despite elevated heart rate, dose reduction in cardiac computed tomography is possible.
•
Prospective systolic gating and automated tube voltage selection enable 50 % dose reduction.</description><identifier>ISSN: 0938-7994</identifier><identifier>EISSN: 1432-1084</identifier><identifier>DOI: 10.1007/s00330-015-3650-2</identifier><identifier>PMID: 25913571</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Adult ; Aged ; Aged, 80 and over ; Automation ; Cardiac ; Cardiac-Gated Imaging Techniques - methods ; Cardiology ; Contrast agents ; Coronary vessels ; Coronary Vessels - diagnostic imaging ; Denervation ; Diagnostic Radiology ; Electrocardiography - methods ; Female ; Follow-Up Studies ; Heart - diagnostic imaging ; Heart rate ; Heart Transplantation ; Heart transplants ; Humans ; Imaging ; Internal Medicine ; Interventional Radiology ; Male ; Medical imaging ; Medicine ; Medicine & Public Health ; Middle Aged ; Neuroradiology ; Postoperative Complications - diagnostic imaging ; Prospective Studies ; Radiation ; Radiation Dosage ; Radiographic Image Interpretation, Computer-Assisted ; Radiology ; Reproducibility of Results ; Retrospective Studies ; Scanners ; Systole ; Tomography ; Tomography, Spiral Computed - methods ; Tomography, X-Ray Computed - methods ; Ultrasound ; Veins & arteries ; Young Adult</subject><ispartof>European radiology, 2015-08, Vol.25 (8), p.2310-2317</ispartof><rights>European Society of Radiology 2015</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c541t-2641b0118c414894001e3704ea4c59dbc65363eb442423af2e26b2316f5e53463</citedby><cites>FETCH-LOGICAL-c541t-2641b0118c414894001e3704ea4c59dbc65363eb442423af2e26b2316f5e53463</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1007/s00330-015-3650-2$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1007/s00330-015-3650-2$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>314,777,781,27905,27906,41469,42538,51300</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/25913571$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Beitzke, D.</creatorcontrib><creatorcontrib>Berger-Kulemann, V.</creatorcontrib><creatorcontrib>Schöpf, V.</creatorcontrib><creatorcontrib>Unterhumer, S.</creatorcontrib><creatorcontrib>Spitzer, E.</creatorcontrib><creatorcontrib>Feuchtner, G.

To prospectively evaluate image quality (IQ) and radiation dose of dual-source cardiac computed tomography (CCTA) using different imaging protocols.
Methods
CCTA was performed in 150 patients using the retrospective ECG-gated spiral technique (rECG) the prospective ECG-gated technique (pECG), or the prospective ECG-gated technique with systolic imaging and automated tube voltage selection (pECGsys). IQ was rated using a 16-segment coronary artery model. Techniques were compared for overall IQ, IQ of the large and the small coronary artery segments. Effective dose was used for comparison of radiation dose.
Results
Overall IQ and IQ of the large segments showed no differences between the groups. IQ analysis of the small segments showed lowered IQ in pECGsys compared to rECG (
p
= 0.02), but not to pECG (
p
= 0.6). Effective dose did not differ significantly between rECG and pECG (
p
= 0.13), but was significantly lower for pECGsys (
p
< 0.001 vs. rECG and pECG).
Conclusion
Radiation dose of dual-source CCTA in heart transplant recipients is significantly reduced by using prospective systolic scanning and automated tube voltage selection, while overall IQ and IQ of the large coronary segments are maintained. IQ appears to be lower compared to retrospective techniques with regard to small coronary segments.
