Coronary CTA cuts costs for chest pain care

For patients with chest pain and a low risk of coronary artery disease (CAD), diagnosis of CAD based on coronary CT angiography (CTA) was more cost-effective than standard care, according to a new study from Argentina. The researchers examined the cost-effectiveness of a primary strategy of coronary CTA for evaluating CAD in low-risk patients with acute chest pain, compared to standard management for diagnosis.

Pediatric CT dose drops with breast shields plus tube modulation

Considering the heightened sensitivity of young patients to radiation's ill effects, and the approximately 7 million CT scans of U.S. children annually, radiologists are working overtime to minimize the dose for these patients. Researchers from Duke University Medical Center in Durham, NC, have recently found that the radiation dose of pediatric thoracic CT scans can be cut by more than half using breast shields with dose modulation software.

Accuracy of polyp measurements depends on CT values

Polyps are most accurately measured at threshold values of approximately -500 HU, according to new Korean research that examined measurements at virtual colonoscopy. The study also found that the sizes of colorectal polyps varied significantly depending on the CT values used to define their contours.

MR-IMPACT trial: CMR equivalent to SPECT for stenosis detection

In a prospective, randomized trial conducted at 18 sites internationally, MR first-pass myocardial perfusion imaging (perfusion-CMR) was at least equivalent to SPECT for detecting coronary artery stenosis, according to a new report in the European Heart Journal.

Concurrent CAD read yields greater VC efficiency, at a cost

Incorporating computer-aided detection (CAD) results into the initial polyp search when reading virtual colonoscopy studies is more efficient than using CAD as a second reader, according to a multicenter study from London. At the same time, sensitivity was maximized when CAD was used in its traditional role as a second reader, although the sensitivity difference between the two reading approaches didn't quite reach statistical significance.

Flat-panel CT falls short in cerebral bleed assessment

Flat-panel CT has a big advantage in the interventional suite, where it can potentially detect cerebral microbleeds without having to stop the procedure and send the patient to a conventional CT scanner. But according to two new studies, flat-panel images still can't match those of conventional CT for detecting cerebral hemorrhage.

Representative Ga-68 FAPI-04 and F-18 FDG-PET/CT images of responders at three month follow-up. Patient #11 was a 50-year-old man with 28 affected joints detected in PET/CT. Joint activity decreased after treatment with Tripterygium wilfordii, methotrexate, adalimumab, and prednisone. In patient #8 (a 65-year-old woman), Ga-68 FAPI-04 PET/CT showed 12 affected joints. Joint activity decreased from baseline after three months of treatment with Tripterygium wilfordii and methotrexate.

In an example image from the study, F-18 FDG-PET/MRI fusion image (A) and PET 3D image (D) show a moderately increased FDG uptake in muscles around hip joints. T2 IDEAL WATER image (B) shows increased T2 signal; LAVA WATER (C) image shows mild enhancement in these muscles. Findings were suspicious of myositis, which was histopathologically confirmed.
