A Novel Splenic Vein Flow Volume to the Portal Vein Flow Velocity Index as a Predictor for the Degree of Esophageal Varices in Liver Cirrhosis Patients.

Bleeding esophageal varices (EV) have the highest mortality rate from all complications of liver cirrhosis (LC). Several Doppler ultrasound (DUS) studies have been done on the splenic or portal vein (PV) to evaluate the hemodynamic of the esophageal vein. Our study focused on finding a better index using the ratio from two parameters correlated with EV, splenic vein flow volume (SFV), and PV flow velocity.

Evaluation of juxtapapillary duodenal diverticula using multiplanar reformation in MDCT: correlation with ERCP findings.

Objective: To determine the ability of multidetector computed tomography (MPR-MDCT) to identify and classify the juxtapapillary duodenal diverticulum (JPDD), with ERCP findings as the gold standard.

Methods: We retrospectively reviewed all ERCP examinations (n: 455) performed between January 2010 to December 2018 and selected 105 patients with JPDD as the inclusion criteria. Of those, 28 patients were excluded because of advanced pancreatic carcinoma, incomplete MDCT examinations and biliary catheter insertion.

Physiological 18F-FDG uptake in the normal adult anal canal: evaluation by PET/CT.

Objective: Despite their benefit for detecting primary tumors, data for normal F-fluoro-2-deoxy-D-glucose (FDG) uptake in the anal canal are insufficient. Here we used positron emission tomography-computed tomography (PET/CT) to determine the uptake of FDG in the normal adult anal canal (AC) and to evaluate its clinical significance compared with that of anal cancer.

Methods: We conducted a retrospective study of-PET/CT images in the anal region, of 201 consecutive patients without symptoms or pathology taken from January 2015 to August 2019, after excluding two patients (one each with Crohn's disease and hemorrhoid).

Subcapsular beaded appearance of the kidney on contrast-enhanced CT: indicative of dilated subcapsular lymphatics?

Aim: To assess the renal subcapsular beaded appearance (RSBA) seen on contrast-enhanced multidetector-row computed tomography (CT).

Materials And Methods: In total, 2,020 consecutive MDCT examinations with both non-contrast-enhanced and contrast-enhanced procedures were assessed retrospectively to identify interconnecting lobular structures in the renal subcapsular area that created a beaded appearance on contrast-enhanced CT. Positive cases were investigated for CT attenuation on unenhanced CT and were then compared with fat-suppressed heavily T2-weighted magnetic resonance imaging (MRI) and follow-up CT if available.

18F-FDG uptake in the normal appendix in adults: PET/CT evaluation.

Objective: This study aimed to determine the level of F fluorodeoxyglucose (F-FDG) activity in the normal adult appendix using positron emission tomography/computed tomography (PET/CT).

Materials And Methods: We performed a retrospective review of PET/CT images using F-FDG in 563 consecutive asymptomatic adult patients without appendiceal pathology. We excluded 257 patients for an undetected or obscured appendix and three patients for appendicitis found on CT imaging.
