Purpose: To attempt a quantitative analysis of pancreatic echogenicity on transabdominal ultrasonography (US) and evaluate the correlation between pancreatic echogenicity and metabolic syndrome (MetS).
Methods: We retrospectively evaluated transabdominal sonograms from 286 subjects. Mean pancreatic body brightness, mean perihepatic fat brightness, and the pancreato-perihepatic fat index (PPHFI) were measured, and reproducibility was analyzed using intraclass correlation coefficients. Associations between the PPHFI and MetS components were analyzed. The optimal PPHFI cutoff value to predict MetS was calculated.
Results: Reproducibility was good for mean pancreatic body brightness, mean perihepatic fat brightness, and PPHFI with intraclass correlation coefficients of 0.98, 0.95, and 0.95, respectively. Each MetS component showed a significant association with PPHFI. Waist circumference had the strongest association (r = 0.55, p < 0.0001). PPHFI was significantly higher in the MetS (+) group than the MetS (-) group (p < 0.0001), and PPHFI was an independent factor predicting MetS (p = 0.02; odds ratio, 2.89). The best PPHFI cutoff value to predict MetS was 1.97, with a relatively high negative predictive value of 94.1%.
Conclusions: We quantitatively analyzed pancreatic echogenicity using the PPHFI on US and found that an increased PPHFI was significantly correlated with MetS. Because increased PPHFI on US may indicate MetS, radiologists and clinicians need to be aware of its implications.

The case pertains to a 29-year-old male who presented with epigastric pain at the hospital. On evaluation, he was sonographically detected to have "comet tail" reverberation artifacts involving the echogenic floaters in the lumen of the urinary bladder. The patient was subsequently diagnosed with Type V hyperlipidemia and acute pancreatitis.

Article Synopsis
- Contrast-enhanced intraoperative ultrasonography (CE-IOUS) is important for identifying colorectal liver metastases (CLM) during surgeries, but using artificial intelligence in this field has been limited.
- The study created an automatic tumor detection model using a Mask region-based convolutional neural network (Mask R-CNN), utilizing CE-IOUS images from 121 patients, resulting in two initial models (BRM and SM) and a combined model (CM).
- The combined model (CM) showed the best performance with a 96.5% accuracy and an AUC of 0.99, indicating that the integration of image- and algorithm-based methods significantly improves CLM detection.

Acute cholecystitis is an inflammatory condition of the gallbladder typically incited by mechanical obstruction. Accurate diagnosis of this common clinical condition is challenging due to variable imaging appearances as well as overlapping clinical manifestations with biliary colic, acute hepatitis, pancreatitis, and cholangiopathies. In acute cholecystitis, increased dilatation and high intraluminal pressures lead to gallbladder inflammation and may progress to gangrenous changes, focal wall necrosis, and subsequent perforation.

Metastases to the liver from gastroenteropancreatic neuroendocrine tumors are varied in their presentation and echogenicity on ultrasound. We present a case of adenocarcinoma of the pancreas with sporadic neuroendocrine differentiation and metastasis to the liver, referred for inclusion in a clinical study. Standard ultrasound showed two hypoechoic focal liver lesions.

Article Synopsis
- - Abdominal fat necrosis in camels often appears incidentally during exams, presenting as hard masses; the differential diagnosis can include other serious conditions like tumors.
- - A 7-year-old female dromedary camel experienced weakness and weight loss, leading to various treatments that were ineffective until advanced diagnostic methods were used, revealing multiple masses and other abnormalities.
- - Transabdominal ultrasonography proved essential for identifying potential abdominal masses and facilitating biopsy, but histopathological analysis ultimately confirmed the diagnosis of abdominal fat necrosis and associated conditions.
