This is the first case report of 43-year-old lady with a myxoid hepatic adenoma which demonstrated significant contrast uptake during hepatobiliary phase imaging. This highlights the potential for a missed diagnosis and likely subsequent malignant transformation in a young patient in whom it was initially presumed to be focal nodular hyperplasia with no further surveillance.

- Pancreatic ductal adenocarcinoma (PDAC) is a serious cancer where accurately assessing resectability through CT scans is essential for determining the best treatment options for patients.
- In a study involving 96 clinicians, it was found that there was significant variability in how different surgeons and radiologists agreed on the resectability of pancreatic tumors based on CT scans.
- The results highlighted a fair overall agreement score of 0.32, with radiologists demonstrating better consistency than surgeons, indicating a need for more standardized assessment processes and central reviews in future treatments and studies.
Introduction: Gastric adenocarcinoma is a known complication of partial gastrectomy. Jaundice from gastric adenocarcinoma usually occurs in the setting of hepatic nodal or parenchymal metastasis. This case demonstrates an unusual level of biliary obstruction from gastric adenocarcinoma.

Clinical suspicion of PE mandates therapeutic anticoagulation, adding a further insult to those of trauma and surgery in a physiologically frail population. The aim of the study was to evaluate for the presence of PEs by performing postoperative CT pulmonary angiography (CTPA) in patients who demonstrated intraoperative, or early postoperative cardiorespiratory lability following surgery with a cemented prosthesis for intracapsular hip fracture.

Materials And Methods: Using a readily available power monitor, we calculated the power consumption of different devices around our department. In particular, we calculated the financial and environmental cost of leaving equipment on overnight and/or at weekends.
Objectives: The purpose of this study was to determine the particulate concentration in a gelatin-based ultrasound phantom for lesion biopsy at 6 cm in depth to reduce visualization of the biopsy needle in the near field, simulating subcutaneous fat and tissue echogenicity, and maintain target lesion visualization.
Methods: Four gelatin-based phantoms with cornstarch at concentrations of 4, 8, 12, and 16 g/L and an anechoic gelatin target at 7 cm in depth were rated on a 5-point scale by readers for visibility of the target lesion, similarity of near-field to abdominal subcutaneous fat echogenicity, and visibility of a 22-gauge spinal needle in the phantom. A timed sonographically guided localization task was performed on the anechoic target by 4 radiology residents using the 22-gauge spinal needle.
The diagnosis of a pancreatic mass lesion in the presence of chronic pancreatitis can be extremely challenging. At the same time, a high level of certainty about the diagnosis is necessary for appropriate management planning. The aim of this study was to establish current best evidence about which imaging methods reliably differentiate a benign from a malignant lesion, and show how that evidence is best applied.

Zanzibar implemented artemisinin-based combination therapy (ACT) for uncomplicated malaria in late 2003 and long-lasting insecticidal nets (LLINs) from early 2006. ACT is provided free of charge to all malaria patients, while LLINs are distributed free to children under age 5 y ("under five") and pregnant women.

Objectives: To quantify the use and clinical relevance of blood cultures obtained in the emergency department.
Methods: A retrospective study of blood cultures taken in the emergency department between 1 January 2003 and 31 December 2004.
