Bioengineering (Basel)
. 2024 Mar;
11(3).
PMID: 38534501
Deep learning (DL) algorithms used for DOTATATE PET lesion detection typically require large, well-annotated training datasets. These are difficult to obtain due to low incidence of gastroenteropancreatic neuroendocrine tumors (GEP-NETs)...

Magn Reson Med
. 2017 Apr;
79(2):968-973.
PMID: 28444805
Purpose: To develop a fast 2D method for MRI near metal with reduced B in-plane and through-slice artifacts. Methods: Multi-spectral imaging (MSI) approaches reduce artifacts in MR images near metal,...

Pediatr Radiol
. 2014 Dec;
45(6):847-54.
PMID: 25433510
Background: Single-shot fast spin echo (SSFSE) is particularly appealing in pediatric patients because of its motion robustness. However radiofrequency energy deposition at 3 tesla forces long pauses between slices, leading...
