Optimization of Pulsed Saturation Transfer MR Fingerprinting (ST MRF) Acquisition Using the Cramér–Rao Bound and Sequential Quadratic Programming

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a method for optimizing pulsed saturation transfer MR fingerprinting (ST MRF) acquisition. Methods The Cramér–Rao bound (CRB) for variance assessment was employed on Bloch–McConnell‐based simulated signals, followed by a numerical sequential quadratic programming optimization and basin‐hopping avoidance of local minima ...

Multiparametric MRI to Predict Response to Irreversible Electroporation Plus Anti‐PD‐1 Immunotherapy in Pancreatic Ductal Adenocarcinoma

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate contrast‐enhanced T1‐weighted MRI and diffusion‐weighted magnetic resonance imaging (DWI) for early prediction of tumor response to combined irreversible electroporation (IRE) and anti‐PD‐1 immunotherapy. Methods Murine pancreatic ductal adenocarcinoma (PDAC) cells KRAS* were inoculated into the pancreas of C57BL/6 mice.

Sarcomatoid carcinoma arising in the pulmonary artery

Malignancy Spectrum, EarlyView.
Abstract Background Sarcomatoid carcinoma is a rare and aggressive malignancy with a poor prognosis, capable of arising in diverse tissues. Pulmonary artery sarcomatoid carcinoma is particularly uncommon and highly invasive. Case Presentation We present the case of a 40‐year‐old male who experienced dry cough and dyspnea, and was subsequently diagnosed
