Artificial Intelligence‐Estimated Intrapancreatic Fat and Its Relationship to Familial and Germline Pancreatic Cancer Risk

Tom Konikoff, Laurens Janssens, Hiroaki Takahashi, Garima Suman et autres

BACKGROUND: Family history of pancreatic cancer (PC), pathogenic germline variants (PGVs), and increased intrapancreatic fat (IPF) are individually associated with increased PC risk. Whether IPF is elevated in high-risk individuals (HRIs) with PC family history or PGVs is unknown. Although MRI is …

Average-Differential-Coordinates-Based Variable Slip Ratio Control of Electrified Vehicles with Torque Vectoring Differential

Hiroyuki Fuse, Hiroshi Fujimoto, Kaoru Sawase, Naoki Takahashi et autres

These days, the vehicle dynamics control of electric vehicles (EVs) with multi-actuated architectures has been widely investigated. Such EVs have a torque vectoring differential (TVD), which can generate a torque difference between the left and right wheels. As one of TVDs, a …

Optimal Selection of the Effective Echo Time ( TE eff ) for T2 ‐Weighted Fast‐Spin‐Echo MRI of the Prostate at 3.0 T: Effect on Lesion Conspicuity

Dahan Kim, Ronard Pabi, Eric A. Borisch, Adam T. Froemming et autres

ABSTRACT Background Clinical T 2 ‐weighted (T2W) MRI of prostate cancer (PCa) usually implements a 2D fast‐spin‐echo (FSE) sequence, but understanding the echo‐time‐dependent contrast behavior is not straightforward due to the complicated FSE signal evolution. Consequently, consensus‐based recommendations on the optimal effective …

Risk factors of postoperative complications and prognostic factors in patients undergoing esophagectomy reconstructed with colonic interposition

Naoki Takahashi, Akihiko Okamura, Masayoshi Terayama, Takashi Kato et autres

Colonic interposition following esophageal resection remains challenging. Few studies have investigated the risk factors for postoperative complications and the prognostic factors in patients who underwent this type of surgery. We evaluated 83 patients who underwent esophagectomy with colonic interposition for esophageal and …
