CT enterography answers range of small-bowel questions
Some radiologists do their best to avoid CT enterography, but they're missing out on a wide range of diagnoses that alternative exams can't provide. Dr. Patrick Rogalla of Charité Hospital in Berlin offers advice for maximizing the value of CT enterography exams for indications ranging from tumor search to inflammatory bowel disease.

Two-segment CTA reconstruction aids images, not accuracy
For patients with faster heart rates, the use of two-segment reconstruction improves image quality at 64-slice coronary CT angiography (CTA), according to a study from Germany. Among all patients, however, accuracy was not improved using two-segment when compared to single-segment reconstruction.

Homogeneity at CT distinguishes renal cysts from cancer
Renal cysts are common and benign; renal carcinoma is not. And distinguishing some high-attenuating cysts from cancer on a typical unenhanced CT scan can be difficult, if not impossible. But researchers from Yale University think they've succeeded in sorting them out fairly accurately, if only to inform the decision for the next exam.

Translucency rendering aids prepless 3D VC
The use of primary 3D interpretation isn't generally recommended for reading reduced-prep virtual colonoscopy (VC) data. Reading is time-consuming, and 3D endoluminal views can make it difficult to distinguish from residual stool difficult. But a new study says that reading reduced-prep data in 3D is not only possible but accurate and time-efficient if a software translucency rendering tool is applied.

CT finds high-risk plaque with nanoparticle contrast
A new animal study by researchers in the U.S. and France brings intriguing new possibilities to CT with its use of a nanoparticulate contrast agent administered before scanning to detect unstable atherosclerotic plaques. The group aims to someday detect human plaques at the greatest risk of rupture while there is time to prevent it.

Study: VC is cost-effective in efficient exam settings
Even among patients at high risk of colorectal polyps and cancer, virtual colonoscopy can be a cost-effective way of finding lesions, according to a study from Denmark. The total costs of VC and conventional colonoscopy were comparable even when the conventional exam and polypectomy were performed on polyps 5-6 mm or larger, according to the researchers.

Water enema may improve MDCT colon cancer staging
Although MRI is still the gold standard when it comes to colorectal cancer staging, a new study from Italy shows that preoperative multidetector-row CT (MDCT) staging using a water enema may offer some advantages over air insufflation. Water appears to improve the ability to assess local disease extent by slightly increasing the density difference between the colon wall and lumen.
