16-slice CT: achievable effective doses of common protocols in comparison with recent CT dose surveysA J van der Molen
Department of Radiology C 2S, Leiden University Medical Center, Albinusdreef 2, NL 2333 ZA Leiden, The Netherlands
Br J Radiol 80:248-55. 2007..Thus, with dose-optimized protocols 16-slice CT can achieve equal to lower effective doses in examinations of the chest and abdomen compared with 4-slice CT, while doses can remain stable in the brain...
CT urography: definition, indications and techniques. A guideline for clinical practiceAart J van der Molen
Department of Radiology C 2S, Leiden University Medical Center, Albinusdreef 2, 2333 ZA, Leiden, The Netherlands
Eur Radiol 18:4-17. 2008..A low-dose (CTDIvol 2-3 mGy) unenhanced series can be added on indication. The expert-based CTU guidelines provide recommendations to optimize techniques and to unify the radiologist's approach to CTU...
Performance of longitudinal and volumetric tube current modulation in a 64-slice CT with different choices of acquisition and reconstruction parametersAart J van der Molen
Department of Radiology C 2S, Leiden University Medical Center, Albinusdreef 2, NL 2333 ZA Leiden, The Netherlands
Phys Med 28:319-26. 2012..6%. In conclusion, (SURE)Exposure 3D resulted in more uniform image quality at a lower dose. Volumetric TCM shows improved results over longitudinal TCM...
Hematuria: a problem-based imaging algorithm illustrating the recent Dutch guidelines on hematuriaAart J van der Molen
Department of Radiology, Leiden University Medical Center, Leiden, The Netherlands
AJR Am J Roentgenol 198:1256-65. 2012..Given the a priori low likelihood of cancer in hematuria, risk categories should be established and imaging algorithms should be tailored to populations at low-risk, medium-risk and high-risk for developing urothelial cancer...
Overranging in multisection CT: quantification and relative contribution to dose--comparison of four 16-section CT scannersAart J van der Molen
Department of Radiology C 2S, Leiden University Medical Center, Albinusdreef 2, NL 2333 ZA Leiden, The Netherlands
Radiology 242:208-16. 2007..To quantify the number of overrange rotations and to assess their relative contribution to organ and effective doses at 16-section body computed tomography (CT)...
Extracellular gadolinium-based contrast media: differences in diagnostic efficacyAart J van der Molen
Department of Radiology C 2S, Leiden University Medical Centre, Albinusdreef 2, NL 2333 ZA Leiden, The Netherlands
Eur J Radiol 66:168-74. 2008..Agents with higher concentration or protein binding may be relatively better suitable for selected applications (e.g. perfusion MRI). The higher relaxivity agents may be used in somewhat lower doses than the extracellular agents...
Nephrogenic systemic fibrosis and the role of gadolinium contrast mediaA J van der Molen
Department of Radiology, Leiden University Medical Center, Leiden, The Netherlands
J Med Imaging Radiat Oncol 52:339-50. 2008..Other gadolinium contrast media should only be used after careful consideration of risks versus benefits. Post-procedural haemodialysis is only indicated in patients on regular dialysis...
