CT texture analysis for differentiating between peritoneal carcinomatosis and peritoneal tuberculosis: a cross-sectional study
ConclusionCT texture parameters of omental lesions differed significantly between patients with PTB and those with PC, which may help clinicians in differentiating between the two entities.Graphical Abstract (Source: Abdominal Imaging)

Integrated FDG-PET/CT contribution over cross-sectional imaging in recurrence or progression of pancreaticobiliary neoplasms
ConclusionFDG-PET/CT and cross-sectional imaging have different advantages and shortcomings. In recurrence/progression, recognition of early changes is more feasible by CT/MRI. However, inconsistency of morphologic and metabolic findings is important reason of cross-sectional imaging failure. FDG-PET/CT is superior in showing extraabdominal metastases, but missing small-volume lesions and misinterpreting inflammatory changes are still a problem lowering its sensitivity. Nevertheless FDGPET/CT is good option for guiding undetermined imaging findings or clinic-radiologic mismatch. (Source: Abdominal Imaging)

CT angiography for characterization of advanced placenta accreta spectrum: indications, risks, and benefits
AbstractPlacenta accreta spectrum disorder (PASD) encompasses various types of abnormal placentation in which chorionic villi directly adhere to or invade the myometrium. The incidence of PASD has dramatically risen in the US over the past 3 decades owing to the increased rates of patients undergoing cesarean sections. While PASD remains a significant cause of maternal morbidity and mortality, accurate prenatal identification and characterization of PASD is associated with improved outcomes. Although ultrasound is the first-line imaging modality in the evaluation of PASD, with MRI serving as an adjunct, computed tomography...

Evaluation of 18 CT signs in diagnosing cecal volvulus: a multi-reader retrospective study
ConclusionCT signs for cecal volvulus that have high sensitivity and specificity include: transition point, bird beak, and X-marks-the-spot and were reliable in distinguishing non-volvulus mimickers. If the following four features were present: transition point, bird beak, coffee bean, and whirl, there was excellent prediction (AUC = .979) for cecal volvulus. (Source: Abdominal Imaging)

Prediction of recurrence risk factors in patients with early-stage cervical cancers by nomogram based on MRI handcrafted radiomics features and deep learning features: a dual-center study
ConclusionA DLRN based on intratumoral and peritumoral regions had the potential to predict and stratify recurrence risk factors for early-stage cervical cancers and enhance the value of individualized precision treatment. (Source: Abdominal Imaging)

A meta-analysis of the performance of ultrasound, hepatobiliary scintigraphy, CT and MRI in the diagnosis of acute cholecystitis
ConclusionRecent data suggests that CT may have a higher sensitivity than US for diagnosing acute cholecystitis, with similar specificity. Cholescintigraphy remains a highly sensitive modality with lower specificity than previously reported. MRI remains under studied, but with promising results. (Source: Abdominal Imaging)

A novel perspective on constipation secondary to sigmoidocele: a retrospective study
ConclusionOur study presents a novel sigmoidocele classification. The anatomic appearance and location of the herniated sigmoid colon observed using fluoroscopy during defecation may help improve the clinical awareness of ODS caused by sigmoidocele. (Source: Abdominal Imaging)

Iodine density mapping for the diagnosis of acute bowel ischemia using fast kV-switching dual-energy CT
ConclusionNo significant difference for the diagnosis of ABI was found using supplementary iodine mapping. Our study may suggest a trend of increased specificity and decreased sensitivity, hence, the use of supplementary iodine mapping should be carefully considered. (Source: Abdominal Imaging)

Discrepant guidelines in the evaluation of hematuria
ConclusionThere is no universally agreed upon algorithm for diagnostic evaluation. Discrepancies centered on the role of upper tract imaging with ultrasound versus CT. Prospective studies and/or repeat simulation studies that apply newly updated guidelines are needed to further clarify the role of imaging, particularly for patients with microhematuria with no and intermediate risk factors.

Prediction of mortality and overt hepatic encephalopathy undergoing transjugular intrahepatic portosystemic shunt: a retrospective cohort study
ConclusionPost-TIPS OHE and Child-Pugh grade are independent prognostic factors for early mortality in cirrhosis patients, thus we construct a simple and convenient prediction model for post-TIPS OHE to identify high-risk patients preoperatively.Graphical abstract (Source: Abdominal Imaging)
