• Monitoring neurointerventional radiation doses using dose-tracking software: implications for the establishment of local diagnostic reference levels 

  Acton, Holly; James, Karl; Kavanagh, Richard G.; O'Tuathaigh, Colm; Moloney, Deirdre; Wyse, Gerald; Fanning, Noel; Maher, Michael M.; O'Connor, Owen J. (Springer Verlag, 2018-04-12)

  Objectives: There is potential for high radiation exposure during neurointerventional procedures. Increasing regulatory requirements mandate dose monitoring of patients and staff, and justification of high levels of radiation ...
• Determination of a suitable low-dose abdominopelvic CT protocol using model-based iterative reconstruction through cadaveric study. 

  Moloney, Fiachra; Twomey, Maria; Fama, Daniel; Balta, Joy Y.; James, Karl; Kavanagh, Richard G.; Moore, Niamh; Murphy, Mary J.; O'Mahony, Siobhan M.; Maher, Michael M.; Cryan, John F.; O'Connor, Owen J. (Wiley, 2018-04-15)

  Introduction: Cadaveric studies provide a means of safely assessing new technologies and optimizing scanning prior to clinical validation. Reducing radiation exposure in a clinical setting can entail incremental dose ...
• Reduction of guide needle streak artifact in CT-guided biopsy 

  McWilliams, Sebastian R.; Murphy, Kevin P.; Golestaneh, Safieh; O'Regan, Kevin N.; Arellano, Ronald S.; Maher, Michael M.; O'Connor, Owen J. (Elsevier, 2014-10-11)

  Purpose: Computed tomography (CT)–guided core needle biopsy (CNB) can be affected by streak artifact obscuring the needle tip. This study investigates factors that influence the occurrence and severity of streak artifact ...
• The role of imaging in the investigation of painless hematuria in adults 

  O'Regan, Kevin N.; O'Connor, Owen J.; McLoughlin, Patrick; Maher, Michael M. (Elsevier, 2009-07-10)

  The radiologic investigation of asymptomatic hematuria has changed significantly due to the introduction of new imaging modalities and innovative techniques, such as computed tomography urogaphy, which allows a comprehensive ...
• Radiologic imaging in cystic fibrosis: cumulative effective dose and changing trends over 2 decades 

  O'Connell, Oisin J.; McWilliams, Sebastian; McGarrigle, AnneMarie; O'Connor, Owen J.; Shanahan, Fergus; Mullane, David; Eustace, Joseph; Maher, Michael M.; Plant, Barry J. (Elsevier, 2015-12-16)

  Objective: With the increasing life expectancy for patients with cystic fibrosis (CF), and a known predisposition to certain cancers, cumulative radiation exposure from radiologic imaging is of increasing significance. ...
