CT angiography (CTA) using 64-MDCT enables timely evaluation of injuries associated with blunt neck trauma. The purpose of this article is to familiarize the reader with the most frequent CTA signs of blunt vascular injury. ⋯ CTA is a valuable tool to detect blunt vascular injuries, especially using its multiplanar and 3D reconstruction capabilities.

ReviewGround-glass nodules on chest CT as imaging biomarkers in the management of lung adenocarcinoma.
The purpose of this article is to review the clinical significance of ground-glass nodules (GGNs) in the management of lung adenocarcinoma. ⋯ GGNs can serve as imaging biomarkers that represent the bronchioloalveolar carcinoma component in adenocarcinoma on histology and indicate a better prognosis in patients with lung adenocarcinoma. The evolution of GGNs reflects the multistep progression of adenocarcinoma. Despite the high probability of malignancy of GGNs, the possibility of overdiagnosis should be considered in the management of GGNs.

ReviewIncidental thyroid nodules on chest CT: Review of the literature and management suggestions.
This article will review the current literature regarding the detection of thyroid nodules with an emphasis on CT diagnosis. We will also discuss management strategies. ⋯ With advances in cross-sectional imaging, the detection of incidental thyroid nodules has increased significantly. Detection of thyroid nodules is common on chest CT that is being performed for unrelated reasons. The workup of these nodules can be timeconsuming and expensive.

ReviewEmbryology and developmental defects of the interatrial septum.
The various types of atrial septal defects (ASDs) can be differentiated on the basis of their imaging appearance on MDCT. ⋯ It is fundamental for the cardiac imager to understand the embryologic development of the interatrial septum and the morphogenic differences of ASDs.
