Italian CT trial boosts lung cancer screening
April 19, 2017 -- An Italian CT lung cancer screening trial has found low-dose CT screening could reduce lung cancer and overall mortality, and it is the first European study to show results clearly in the same direction of other major lung cancer screening trials.
Ultralow-dose CT works for emphysema quantification
April 18, 2017 -- A Swiss study has shown that a CT protocol using tin filtration and iterative reconstruction reduces radiation dose levels to the equivalent of a chest x-ray for lung volumetry and also the detection and quantification of emphysema. The results nudge ultralow-dose CT ever closer to routine workup of chest pathologies.
Bamberg provides update on National Cohort study
April 17, 2017 -- The NAKO (Nationale Kohorte) Health Study in Germany is a large population-based prospective cohort study, and 3-tesla MRI is playing a central role. In this interview, Dr. Fabian Bamberg speaks about the project, launched three years ago.
Cardiac findings in stroke: What radiologists need to know
April 14, 2017 -- Advances in CT and MRI mean it's feasible now to identify subtle cardiac pathologies responsible for stroke that used to remain unnoticed, and this is putting greater emphasis on the know-how of radiologists, award-winning Spanish researchers believe.
Reduced FDG dose levels for PET/MRI show mixed results
April 13, 2017 -- Even though a lower dose of FDG did not significantly affect lesion detection for most adult cancer patients undergoing a whole-body PET/MRI scan, German researchers recommend that clinicians stay with recommended levels to avoid artifacts, according to a study published in the Journal of Nuclear Medicine.
4 steps to develop hybrid imaging
April 12, 2017 -- Hybrid imaging involves combining two imaging modalities, typically PET and CT, SPECT and CT, or PET and MRI. There are four steps to follow to ensure that hybrid imaging is used to its full potential, Dr. Arturo Chiti writes.
Studies show DBT detects more breast cancers than mammo
April 12, 2017 -- Digital breast tomosynthesis (DBT) identifies more breast cancers than conventional digital mammography, according to two studies presented at ECR 2017. In addition, the recall rates between the two modalities are comparable, researchers found.
Italians show CAD improves prostate biopsy targeting
April 11, 2017 -- An artificial intelligence-based computer-aided detection (CAD) system that analyzes prostate MR images for tumors improves the targeting of core biopsies for cancer diagnosis, according to Italian research presented at ECR 2017. With fine-tuning, the system could improve patient care.
Attention focuses on added value of clinical audits
April 11, 2017 -- Compulsory clinical audits are on the horizon. Skeptics fear they are time-consuming and costly, interrupting daily practice and resulting in stressful and hurried activity followed by a gradual slackening in standards once the audit is over. But a Belgian group thinks otherwise.
IR with CAD permits ultralow lung CT dose
April 10, 2017 -- Iterative reconstruction (IR) can improve lung nodule detection with 3D computer-aided detection (CAD) to the point where nodule detection using ultralow-dose CT is comparable with standard and low-dose exposures, according to researchers from Japan presenting at ECR 2017 in Vienna.
