3D animation of CT images of mastodon rib
The video is made from CT scans that reveal a dense object made from bone embedded in the mastodon rib. The object is shaped to a point, which is penetrated 2.15 cm into the rib, after which it broke after entering the rib and separated from the main shaft. The combined length of the point fragment (tip length plus the length of the embedded and external shaft piece) is 3.5 cm.

Low-kV DECT finds more pathology with less radiation, contrast
By Eric Barnes
Low-kV dual-energy CT (DECT) of the abdomen is gaining currency as a CT technique that can reveal pathology hidden on traditional imaging techniques, using less radiation and less contrast media. It can also be performed using a variety of methods, each with its own strengths and weaknesses.

VC shows mostly advantages in postcolostomy surveillance
By Eric Barnes
Virtual colonoscopy is technically feasible and less invasive than conventional colonoscopy for surveillance after sigmoid colostomy, according to a study in the October American Journal of Roentgenology. But better techniques are needed before it can be used routinely, the researchers said.

'Rapid prototyping' puts CT images in doctors' hands
By Eric Barnes
These days, multidetector-row CT is producing vast quantities of 3D and 4D data for diagnostic and interventional use. But for all its multidimensionality, most of the output is still served up on a flat screen. That could be changing with a process called "rapid prototyping" that creates physical models from imaging data.

320-row scanner cuts contrast dose in coronary CTA
By Eric Barnes
Contrast media dose can be reduced in coronary CT angiography (CCTA) scans acquired with a 320-detector-row scanner without significantly affecting image quality, according to a study in the October edition of the American Journal of Roentgenology.

Software automates CT liver volume measurements
By Erik L. Ridley
An automated software application for determining liver volume on CT images can yield dramatic time savings over manual volumetry techniques when planning liver transplants by reducing variation among radiologists, according to an article in the October issue of the American Journal of Roentgenology.

Hospital-wide CT dose reduction program yields dividends
By Erik L. Ridley
While there are many individual steps that can be taken to reduce CT radiation dose, a comprehensive, hospital-wide dose reduction program provides the most benefit, according to an article published in the October issue of the American Journal of Roentgenology.
