Oronasal fistula development is described anecdotally as a common disease process in the dachshund but little is known about its imaging appearance. This case report describes the clinical presentation, computed tomography (CT) characterisation, dental radiograph confirmation and treatment of bilateral oronasal fistulas in a 14‐year‐old dachshund.
Recently, the acquisition of high-resolution T1 maps in a clinically feasible time frame has been demonstrated with Driven Equilibrium Single Pulse Observation of T1 (DESPOT1). DESPOT1 derives the longitudinal relaxation time, T1, from two or more spoiled gradient recalled echo (SPGR) images acquired with a constant TR and different flip angles. In general, T1 can be estimated from two or more SPGR...
Magnetic Resonance Imaging (MRI) estimation of contrast agent concentration in fast pulse sequences such as Dual Gradient Echo (DGE) imaging is challenging. An Adaptive Neural Network (ANN) was trained with a map of contrast agent concentration estimated by Look-Locker (LL) technique (modified version of inversion recovery imaging) as a gold standard. Using a set of features extracted from DGE MRI...
