Unsuspected finding of right coronary artery occlusion on nongated CT chest.

Myocardial infarction (MI) is the main cause of morbidity and mortality globally. This occurs due to occlusion of the coronary artery resulting in ischemia of the cardiac muscles. Typical symptoms include chest pain and discomfort.

Aortic root measurement on CT: linear dimensions, aortic root area and comparison with echocardiography. A retrospective cross sectional study.

Objective: We sought to assess the different CT aortic root measurements and determine their relationship to transthoracic echocardiography (TTE).

Methods: TTE and ECG-gated CT images were reviewed from 70 consecutive patients (mean age 54 ± 18 years; 67% male) with tricuspid aortic roots (trileaflet aortic valves) between Nov 2009 and Dec 2013. Three CT planes (coronal, short axis en face and three-chamber) were used for measurement of nine linear dimensions.

A case of bilateral pelvic kidneys.

A rare case of bilateral pelvic kidneys detected incidentally on computed tomography.

The many faces of lung adenocarcinoma: A pictorial essay.

Lung adenocarcinoma has a spectrum of appearances on CT, many of which mimic non-malignant processes. The general radiologist has a major role in guiding the management of abnormalities detected on chest CT and an awareness of these appearances is vital. We describe the protean imaging manifestations of lung adenocarcinoma.
