Aortic findings at chest CT predict heart disease, events
Calcifications and other abnormalities of the thoracic aorta on routine chest CT images are highly predictive of cardiovascular events, say the authors of a new study in the November issue of Radiology. The simple model they used to classify multiple aortic findings underscores the value of small abnormalities in uncovering serious disease.

Higher colonoscopy complication rates found in seniors
Seniors who undergo conventional colonoscopy suffer far higher rates of cardiac events and colonic perforations than patients who don't get the procedure, concluded a study to be presented on Wednesday at the 2010 American College of Gastroenterology annual meeting in San Antonio.

CT calcium scoring alters cardiac risk estimates
Ten-year outcomes data from the Rotterdam coronary artery calcium (CAC) study underscore the prognostic power of adding CAC to a traditional risk stratification method. New results in the Journal of the American College of Cardiology show that CAC scores frequently change the risk category for future coronary events in asymptomatic individuals.

Surveillance VC is promising for follow-up after colon surgery
Virtual colonoscopy offers several advantages for the surveillance of patients after curative colon cancer surgery, according to a study published online in Radiology. In more than 700 patients, VC detected 100% of the metachronous or recurrent cancers, along with several unsuspected extracolonic cancers.

A 60-year-old male patient with clinical suspicion of lung cancer. PET/CT scan showed FDG-avid pulmonary nodules in the upper lobe of the left lung (red arrow), with a size of 2.2 × 1.3 cm, SUVmax of 12.2, Ki-65 min of 0.016 ml/g/min, and Ki-30 min of 0.014 ml/g/min. Surgical pathology confirmed a granulomatous lesion. In addition, PET/CT scan showed many FDG-avid lung nodules in the mediastinum.
