Although CT angiography is more accurate than calcium scoring in demonstrating stenotic coronary artery disease, a calcium score of greater than or equal to 400 may help diagnose disease that is not detected at CT angiography, and CT angiography and calcium scoring combined have the potential to improve the detection of coronary stenoses relative to CT angiography alone.

Fluorocholine PET/CT in Patients with Prostate Cancer: Initial Experience
Fluorocholine PET/CT for the detection of recurrent disease or metastases after radical prostatectomy is a promising field in patients with only biochemical evidence of recurrence but otherwise unremarkable imaging findings.

Gustatory Stimulation Changes the Apparent Diffusion Coefficient of Salivary Glands: Initial Experience
Diffusion-weighted MR imaging allows for the depiction of changes in the salivary glands during gustatory stimulation and shows a biphasic response with an initial drop in apparent diffusion coefficient followed by a slow increase.

Radiology Education in the Digital Era
It takes time and effort, but it is feasible to do everything that was done in the "old-fashioned" film-based hot seat conference with digital methods.
