Diagnosis of acute mesenteric ischemia/infarction in the era of multislice CT

Acute mesenteric ischemia/infarction is a complex and often misdiagnosed syndrome. The availability of new imaging methods, namely multislice computed tomography, has enabled early recognition of signs and symptoms of acute mesenteric ischemia, resulting in timely therapeutic intervention

Accuracy of multislice CT in restaging patients with non-small cell lung carcinoma after neoadjuvant chemotherapy using a multiparametric approach.

The aim of this study was to assess diagnostic accuracy of multislice CT in restaging patients with N2 nonsmall cell lung carcinoma after neoadjuvant chemotherapy, using a multiparametric approach as compared with traditional size-based radiological criteria. All patients staged as N2 at histologic examination after neoadjuvant chemotherapy were correctly staged with multislice CT (sensitivity, specificity, positive and negative predictive value, and accuracy were 100%, 80%, 85%, 100% and 93,7% respectively, vs 34%, 60%, 34%, 60% and 50% using size-based criteria), suggesting that a multiparametric approach results in improved diagnostic accuracy

Update in diagnostic imaging of the thymus and anterior mediastinal masses.

Anterior mediastinal masses include a wide spectrum of malignant and benign pathologies with a large percentage represented by thymic lesions. Distinguishing these masses on diagnostic imaging is fundamental to guide the proper management for each patient. This review illustrates possibilities and limits of different imaging modalities to diagnose a lesion of the anterior mediastinum with particular attention to thymic disease. © Gland Surgery

Quantitative CT perfusion measurements in characterization of solitary pulmonary nodules: new insights and limitations

Although computed tomography (CT) scans remain the basis of morphologic evaluation in the characterization of solitary pulmonary nodules (SPNs), perfusion CT can represent an additional feasible technique offering reproducible measurements, at least in SPNs with a diameter >10 mm. In particular, CT perfusion could reduce the number of SPNs, diagnosed as undetermined at morphologic CT, avoiding long term follow-up CT, FDG-PET studies, biopsy or unnecessary surgery with a significant reduction in healthcare costs. In order to reduce the radiation dose, an optimization of the CT perfusion protocol could be obtained using axial mode acquisition, using shorter acquisition time and adaptative statistical iterative reconstruction algorith
