Open AccessDevelopment and implementation of an ultralow-dose CT protocol for the assessment of cerebrospinal shunts in adult hydrocephalus
Cerebrospinal fluid shunts in the treatment of hydrocephalus, although associated with clinical benefit, have a high failure rate with repeat computed tomography (CT) imaging resulting in a substantial cumulat...

Open AccessC-arm cone-beam CT parenchymal blood volume imaging for transarterial chemoembolization of hepatocellular carcinoma: implications for treatment planning and response
We report on the feasibility of C-arm cone-beam computed tomography (CBCT) parenchymal blood volume imaging (PBVI) performed immediately following transarterial chemoembolization (TACE) of hepatocellular carci...

Open AccessUsing body mass index to estimate individualised patient radiation dose in abdominal computed tomography
The size-specific dose estimate (SSDE) is a dose-related metrics that incorporates patient size into its calculation. It is usually derived from the volume computed tomography dose index (CTDIvol) by applying a c...

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