To identify predictive factors associated with operative morbidity, mortality, and survival outcomes in patients borderline resectable (BR) or locally advanced (LA) pancreatic ductal adenocarcinoma (PDAC) undergoing total neoadjuvant therapy (TNT).The optimal preoperative treatment sequencing for BR/LA PDA is unknown. TNT, systemic chemotherapy followed by chemoradiation (CRT), addresses both occult metastases positive margin risks thus a potentially strategy; however, of perioperative are...
Background: Neoadjuvant therapy (NAT) is used in borderline resectable/locally advanced (BR/LA) pancreatic ductal adenocarcinoma (PDAC). Anatomic imaging (CT/MRI) poorly predicts response, and biochemical (CA 19-9) markers are not useful (nonsecretors/nonelevated) many patients. Pathologic response highly survival post-NAT, but only known postoperatively. Because metabolic (FDG-PET) reveals primary tumor viability, this study aimed to evaluate our experience with preoperative FDG-PET...
To measure the effect of reduced radiation exposure on low-contrast low-attenuation liver lesion detection in an anthropomorphic abdominal phantom by using filtered back projection (FBP) and sinogram-affirmed iterative reconstruction.Eighteen radiologists blinded to study design interpreted randomized image data sets that contained 36 spherical simulated lesions three sizes attenuation differences (5-mm diameter: 12, 18, 24 HU less than 90-HU background insert; 10- 15-mm 6, 18 attenuation)...

Purpose To assess image noise, contrast-to-noise ratio (CNR) and detectability of low-contrast, low-attenuation liver lesions in a semianthropomorphic phantom by using either discrete circuit (DC) detector filtered back projection (FBP) or an integrated (IC) iterative reconstruction (IR) with changes radiation exposure size. Materials Methods An anthropomorphic without 5-cm-thick fat-mimicking ring (widths, 30 40 cm) containing inserts four spherical was scanned five settings on each two...
Purpose To compare the diagnostic accuracy and image quality of computed tomographic (CT) enterographic images obtained at half dose reconstructed with filtered back projection (FBP) sinogram-affirmed iterative reconstruction (SAFIRE) those full-dose CT FBP for active inflammatory terminal or neoterminal ileal Crohn disease. Materials Methods This retrospective study was compliant HIPAA approved by institutional review board. The requirement to obtain informed consent waived. Ninety subjects...
Purpose To develop a two‐stage three‐dimensional (3D) convolutional neural networks (CNNs) for fully automated volumetric segmentation of pancreas on computed tomography (CT) and to further evaluate its performance in the context intra‐reader inter‐reader reliability at full dose reduced radiation CTs public dataset. Methods A dataset 1994 abdomen CT scans (portal venous phase, slice thickness ≤ 3.75‐mm, multiple vendors) was curated by two radiologists (R1 R2) exclude cases with pancreatic...
Prostate-specific membrane antigen (PSMA) is a validated target for molecular diagnostics and targeted radionuclide therapy. Our purpose was to evaluate PSMA expression in hepatocellular carcinoma (HCC), cholangiocarcinoma (CCA), hepatic adenoma (HCA); investigate the genetic pathways HCC associated with expression; detection rate

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive and lethal malignancy. Surgical resection the only curative modality combined with neoadjuvant chemotherapy to improve survival. Given limitations of traditional responses such as cross-sectional imaging (CT/MRI) or tumor markers, carbohydrate antigen 19-9 (CA19-9), 2023 National Comprehensive Cancer Network guidelines included 18 F-fluorodeoxyglucose (FDG)-PET adjunct assess response chemotherapy. There are common...
