Multislice CT may improve virtual colonoscopy results

With multidetector-row CT being used increasingly for virtual colonoscopy exams, researchers are eager to find out if the technology’s prowess in other applications will translate to higher sensitivity and specificity in colorectal cancer detection. So far, indirect comparisons suggest better results using MDCT.

Nodule analysis can help manage CT lung screening patients

A Japanese study has found that high-resolution CT analysis can be used to successfully manage small solitary pulmonary nodules (SPNs). The practice could potentially obviate the need for some follow-up exams and biopsies, according to the paper published in the American Journal of Roentgenology.

MDCT may boost virtual colonoscopy results

Virtual colonoscopy providers are increasingly using multidetector-row CT scanners to screen for colorectal cancer. In theory, their results should begin to reflect MDCT's improved speed and better spatial and temporal resolution compared to single-slice machines.

Colon CAD finds complementary role with radiologists

Research into CAD in virtual colonoscopy has moved beyond feasibility, and into the nitty-gritty of functional assessment. The focus is on the value of CAD schemes in the hands of radiologists, who will ultimately share the job of finding colorectal polyps and cancers with their automated counterparts.

Mummy dearest: CT helps archaeologists dig deeper

By Kate Madden Yee

Radiologists and archaeologists have long been working together to uncover information about ancient artifacts without disturbing them. Although conventional x-ray has produced invaluable information, CT technology, particularly spiral CT with multiplanar display capabilities, is proving helpful for archaeological research.

CT diagnoses peripheral T-cell lymphoma, with limitations

CT can accurately depict gastrointestinal-tract involvement in peripheral T-cell lymphoma (PTCL) if it is not confined to the mucosa, according to Korean researchers. However, the modality may not play a critical role in detecting primary lesions when there is little or no mural involvement.
