Endovascular embolization of persistent liver injuries not responding to conservative management: a narrative review.
J Trauma Inj
September 2023
Department of Radiology, St. Luke's Hospital, Temple University School of Medicine, Bethlehem, PA, USA.
Article Synopsis
- Trauma leads to over five million deaths annually, with liver injuries being common in abdominal trauma, especially in those under 40, where mortality rates from liver-related hemorrhage can be as high as 50%.
- The American Association for the Surgery of Trauma grading scale traditionally classifies liver injuries, but new systems like the World Society of Emergency Surgery classification are taking physiological status into account.
- Advances in diagnostic techniques, including multiphase CT and CEUS, aim to minimize radiation exposure, while nonoperative management combined with angiography shows high success rates in treating liver trauma.
A Triphasic Split-bolus Contrast Injection Protocol for Artery-vein Separation During Pulmonary Computed Tomographic Angiography.
J Thorac Imaging
January 2023
Department of Radiology, National Hospital Organization Kanmon Medical Center, Yamaguchi.
Article Synopsis
- This study investigates a contrast enhancement method using a split-bolus protocol during pulmonary CT angiography to achieve distinct separation of pulmonary arteries and veins with minimal contrast use.
- Fifty patients participated, receiving a specific sequence of contrast and saline injections to optimize image quality, focusing on the timing of left atrium enhancement for better artery-vein differentiation.
- Results showed a significant difference in contrast measurements between the pulmonary arteries and veins, proving that the protocol effectively enhanced visualization for preoperative imaging.
Split-bolus single-pass CT for vascular complications in acute pancreatitis: assessment of radiation dose and multi-phasic contrast enhancement compared to single-bolus multi-pass CT.
Clin Radiol
August 2020
Department of Radiology, Cambridge University Hospitals NHS Trust, Hills Road, Cambridge, CB2 0QQ, UK.
Aim: To assess vascular contrast enhancement and radiation dose of split-bolus single-pass computed tomography (CT) compared to single-bolus multi-pass CT for acquiring a multi-phasic study.
Materials And Methods: Patients who underwent CT for acute pancreatitis were included retrospectively. Thirty consecutive patients scanned with a split-bolus protocol were compared to 30 consecutive patients scanned with a single-bolus protocol.

A review of split-bolus single-pass CT in the assessment of trauma patients.
Emerg Radiol
August 2018
University of Washington, Washington, USA.
Purpose: The purpose of this study was to review and compare the image quality and radiation dose of split-bolus single-pass computed tomography(CT) in the assessment of trauma patients in comparison to standard multi-phase CT techniques.
Methods: An online electronic database was searched using the MESH terms "split-bolus," "dual phase," and "single pass." Inclusion criteria required the research article to compare a split contrast bolus protocol in a single-pass scan in the assessment of trauma patients.
