CAD fails to make up for inexperience in reading VC studies
By Erik L. Ridley
Using computer-aided detection (CAD) software with a 3D display technique can increase sensitivity for inexperienced readers of virtual colonoscopy exams, but it fails to narrow the performance gap with experienced interpreters, according to a study published in the October issue of Clinical Radiology.

CAD enhances breast MRI specificity
By Erik L. Ridley
Although breast MRI is highly sensitive for detecting breast cancer, the technique remains plagued by a relatively low level of specificity. But computer-aided detection (CAD) technology can help reduce false-positive findings, according to research published online this month in European Radiology.

Fuzzy 3D ultrasound CAD sharpens breast cancer sensitivity
By Eric Barnes
A new breast ultrasound computer-aided detection (CAD) application uses a fuzzy 3D image processing scheme to deliver high sensitivity to improve the detection of early breast cancers.

Brazilian team marries lung CAD with PACS
By Eric Barnes
Nearly all computer-aided detection (CAD) systems in clinical use today have a major shortcoming: the need to transfer image data to a separate workstation to run CAD software, with CAD data remaining separate from the PACS images radiologists read in their normal workflow. Researchers from São Paulo may have the answer.

FFDM plus CAD beats analog mammography
By AuntMinnieEurope.com staff writers
Full-field digital mammography (FFDM) with computer-aided detection (CAD) found more cancers than analog mammography in a large screening population, according to a study conducted by Dutch researchers.

CARS report: New CAD tool follows lung nodules over time
By Eric Barnes
BERLIN - It's easy to complain about the insanity of tracking lung nodule changes in multiple CT scans over time, but at least one group is doing something about it, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.

Readers undaunted by VC CAD false positives
By Eric Barnes
Radiologists examining data from virtual colonoscopy studies can easily dismiss increasing numbers of false-positive detections generated by computer-aided detection (CAD) systems, researchers from the U.K. report. But the presence of more false positives makes reading less efficient.

Virtual colonoscopy CAD improves flat-lesion detection
By Eric Barnes
Computer-aided detection (CAD) software can improve the detection of flat lesions at virtual colonoscopy -- as long as the lesions are at least 1 mm high. In a new study from Italy, CAD detected 94% of all flat lesions; however, radiologists dismissed a few of them incorrectly as false positives.

Two lung CAD systems unaffected by low dose
By Eric Barnes
A face-off between two lung nodule computer-aided detection (CAD) systems found a big difference in sensitivity for detecting solid pulmonary nodules, but it also revealed the good news that nodule detection was unaffected by low-dose scanning. The number of false positives also differed significantly between the two systems, researchers from Germany reported.

VC CAD plus 3D improves sensitivity for novice readers
By Eric Barnes
Computer-aided detection (CAD) with 3D viewing improves sensitivity for polyp detection among less experienced readers, and may also speed up reading times and reduce false-positive detections. On the other hand, the performance of experienced readers did not improve significantly with CAD use, researchers from the University of Rome concluded.
