Acta Plane—A New Reference for Virtual Orientation of Cone Beam Computed Tomography Scans: A Pilot Study

Applied Sciences, 2023
Introduction: Cone Beam Computed Tomography (CBCT) scans should be digitally oriented using a reference plane before being evaluated for patient growth and treatment outcome. Current orientation planes are usually dependent on the Porion points.

Effect of delayed acquisition times on Gadolinium-enhanced MRI of the presumably normal canine brain [PDF]

, 2011
A delay in imaging following intravenous contrast medium administration has been recommended to reduce misdiagnoses. However, the normal variation of contrast enhancement in dogs following a delay has not been characterized.

Inter- and Intra-Observer Variability and the Effect of Experience in Cine-MRI for Adhesion Detection

Journal of Imaging, 2023
Cine-MRI for adhesion detection is a promising novel modality that can help the large group of patients developing pain after abdominal surgery. Few studies into its diagnostic accuracy are available, and none address observer variability.
