Two lung CAD systems unaffected by low dose

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 not cost-effective in FOBT-positive screening population

Patients with positive screening results on fecal occult blood tests (FOBTs) should probably head straight to optical colonoscopy for their next exam, according to a new study from the Netherlands. Virtual colonoscopy may not be cost-effective in this population because so many FOBT-positive patients would need referral for polypectomy anyway, the researchers said.

Biological dose measures promise new view of cardiac imaging risk

The development of biological radiation dose measurement portends a future of far greater accuracy in gauging the damage wrought by ionizing radiation in imaging exams. Two studies, focused on cardiac CT and conventional angiography exams, respectively, offer the potential of maximizing image quality while minimizing the potential radiation risk to the patient.

VC CAD plus 3D improves sensitivity for novice readers

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.

Adding chest CT to VC not cost-effective, study finds

Adding a chest CT scan to screening virtual colonoscopy isn't cost-effective in a cohort of average-risk patients, a new model-based analysis concluded. Although the additional anatomic coverage increased the clinical efficiency of CT-based screening, the combined test would not detect enough serious pathology to cover the costs of detection and follow-up of disease.

MDCT holds promise for advanced osteoporosis scan

CT could become an important player in the emerging field of structural bone assessment, according to researchers from Berlin and San Francisco. They believe the modality is capable of evaluating trabecular structures from the extremities to the vertebrae, outperforming even high-resolution peripheral quantitative CT (HR-pQCT) in some conditions.

Virtual colonoscopy CAD finds most cancers

A computer-aided detection (CAD) algorithm designed to find polypoid lesions of the colon also does fairly well at finding frank cancers, researchers from the U.K. concluded. But sensitivity varies depending on the system settings and the quality of the prep.

CT for brain metastasis unnecessary after PET/CT

A CT scan is often ordered to find brain metastases in lung cancer patients. But if a whole-body PET/CT scan is already available from the original workup, there's no need for a dedicated CT scan, according to researchers from Belgium, who found that the CT portion of the PET/CT scan is enough for the initial diagnosis.

Automated CT volumetry of lymph nodes gauges treatment response

Cancer patients who respond to neoadjuvant therapy have a better prognosis than nonresponders, of course, but with the exception of FDG-PET, reductions in the size of tumors treated with chemotherapy or radiation have been difficult to gauge using imaging modalities that are capable of delineating the anatomy.

VC/AAA screening combo cost-effective in older adults

A new analytic model has found that virtual colonoscopy is a highly cost-effective colon cancer screening method for older adults in the Medicare population, especially when combined with screening for abdominal aortic aneurysm (AAA), a test performed using the same CT dataset at little additional cost.
