New cardiac CT guidelines expand use for low-risk patients
New guidelines published on the appropriate use of coronary CT angiography generally recommend broader use in low- and intermediate-risk patients, while discouraging use in high-risk patients or for multiple coronary calcium exams.

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.

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.

Dynamic PET/CT and pathologic images for a 66-year-old male participant. (A) Axial dynamic PET/CT image acquired during intravenous administration of Ga-68 PSMA-11 demonstrates the hypermetabolic primary prostatic tumor. The right-sided portion of the lesion used for volume of interest (VOI) analysis is outlined in pink, reflecting the margins seen on a prior T2-weighted MRI scan. Tumor radiotracer uptake extends across midline into the left anterior apex (*). (B) Axial dynamic PET/CT image acquired during selective right prostatic arterial administration of Ga-68 PSMA-11 demonstrates intense radiotracer uptake in the VOI outlined in pink. There is comparatively minimal uptake in the unperfused left-sided portion of the tumor (*). The arterial sheath and catheters in the right groin are partially visualized (arrow). (C) Photomicrograph (hematoxylin-eosin stain; unmagnified) of the prostatic apex after radical prostatectomy. The midline (dotted line) and dominant tumor margins (solid line) are shown. Small additional areas of carcinoma (■) without T2-weighted MRI correlates were also identified at pathologic examination.
