Pulmonary migration of liquid embolization material: An unusual cause of pulmonary embolism.

Iatrogenic non-thrombotic pulmonary embolism is a rare cause of pulmonary embolism. This case demonstrates the unusual imaging findings associated with pulmonary migration of Precipitating Hydrophobic Injectable Liquid, a liquid embolization material most commonly used in interventional neuroradiological procedures. Chest X-ray and CT Pulmonary Angiogram images are shown.

Can dynamic imaging, using F-FDG PET/CT and CT perfusion differentiate between benign and malignant pulmonary nodules?

Background: The aim of the study was to derive and compare metabolic parameters relating to benign and malignant pulmonary nodules using dynamic 2-deoxy-2-[fluorine-18]fluoro-D-glucose (F-FDG) PET/CT, and nodule perfusion parameters derived through perfusion computed tomography (CT).

Patients And Methods: Twenty patients with 21 pulmonary nodules incidentally detected on CT underwent a dynamic F-FDG PET/CT and a perfusion CT. The maximum standardized uptake value (SUV) was measured on conventional F-FDG PET/CT images.

Are We Missing the Opportunity to Measure Muscle Mass on Computed Tomography Thorax?

Hand grip strength (HGS) and fat free mass index (FFMI) are important indicators of skeletal muscle mass and correlate with prognosis in patients with respiratory diseases. It is also possible to estimate muscle mass by measuring muscle density and volume on cross sectional imaging. We reviewed all patients of the All Wales Cystic Fibrosis Centre who had a computed tomography thorax as part of routine clinical care between 2013 and 2017.

F-Sodium Fluoride Uptake in Abdominal Aortic Aneurysms: The SoFIA Study.

Background: Fluorine-18-sodium fluoride (F-NaF) uptake is a marker of active vascular calcification associated with high-risk atherosclerotic plaque.

Objectives: In patients with abdominal aortic aneurysm (AAA), the authors assessed whether F-NaF positron emission tomography (PET) and computed tomography (CT) predicts AAA growth and clinical outcomes.

Methods: In prospective case-control (n = 20 per group) and longitudinal cohort (n = 72) studies, patients with AAA (aortic diameter >40 mm) and control subjects (aortic diameter <30 mm) underwent abdominal ultrasound, F-NaF PET-CT, CT angiography, and calcium scoring.

The International Association for the Study of Lung Cancer Lymph Node Map: A Radiologic Atlas and Review.

Accurate lymph node staging of lung cancer is crucial in determining optimal treatment plans and predicting patient outcome. Currently used lymph node maps have been reconciled to the internationally accepted International Association for the Study of Lung Cancer (IASLC) map published in the seventh edition of TNM classification system of malignant tumours. This article provides computed tomographic illustrations of the IASLC nodal map, to facilitate its application in day-to-day clinical practice in order to increase the appropriate classification in lung cancer staging.

A phase II trial of low-dose gemcitabine in a prolonged infusion and cisplatin for malignant pleural mesothelioma.

After a favorable experience with gemcitabine at a low dose in a prolonged infusion in combination with cisplatin for advanced non-small-cell lung cancer, here, we present the results from a phase II trial for patients with malignant pleural mesothelioma. Eligible patients had biopsy-proven malignant pleural mesothelioma, were chemo-naive, Eastern Cooperative Oncology Group performance status 0-2, had normal hematopoietic liver and renal function, and gave informed consent. Treatment consisted of gemcitabine 250 mg/m in a 6-h infusion on days 1 and 8 and cisplatin at 75 mg/m on day 2 of a 3-week cycle for four cycles, followed by two additional cycles without cisplatin.
