Diagnostic Imaging

Enhanced dual-source dual-energy CT (DECT) can help differentiate invasive adenocarcinomas from preinvasive lesions which appear as pure ground-glass nodules (pGGNs), according to a small study published in the American Journal of Roentgenology.

“The results of this research are extremely exciting, as it will significantly impact clinical care,” reported study author Mishal Mendiratta-Lala, MD, with the division of abdominal radiology at Michigan Medicine in Ann Arbor.

Whole-body MRI (WB-MRI) staged colorectal and lung cancer patients with accuracy similar to standard staging pathways, but WB-MRI saved valuable time and costs associated with screening, according to results of two new trials published May 9.

The researchers analyzed the frequency and cancer yield of ACR Breast Imaging Reporting and Data System (BI-RADS) 3 lesions in patients who received baseline and non-baseline screening MRIs.

“If (virtual non-contrast) VNC images could provide comparable diagnostic performance in detecting biliary stone disease to (true non-contrast) TNC, we might replace TNC with VNC, and consequently, reduce the radiation dose,” wrote authors of a new study published in the European Journal of Radiology.

The researchers looked at 73 eligible studies consisting of 3,930 malignant and 2,861 benign lesions that evaluated the diagnostic performance of DWI, diffusion-tensor imaging (DTI) and intravoxel incoherent motion (IVIM) in the breast.

“Given that health care systems are limited in their financial resources, competing surveillance strategies should be analyzed for their cost-effectiveness," wrote Paulo Henrique Lima and colleagues, in an April 17 study published in the American Journal of Roentgenology.

Some children in isolated villages have never seen an ultrasound machine, nevermind a portable one. A recent New York Times article provided an in-depth look at how impactful low-cost scanning technology can be to regions that don’t have access to basic imaging modalities.

CT colonography (CTC) achieved a similar positive predictive value (PPV) as colonoscopy during colon cancer screening and can help clinicians care for patients by specifying the nature of exam findings, according to a new study published in the American Journal of Roentgenology.

Rectal cancer patients given a “good prognosis” on MRI may be able to avoid preoperative chemoradiotherapy (CRT), a technique commonly associated with long-term adverse outcomes, according to results of a new study published in JAMA Oncology.

Combining digital breast tomosynthesis (DBT) with digital mammography (DM) can spot additional lesions in patients with breast cancer, reported authors of a recent study published in Radiology. However, the combined method did have limitations.

High-strength 7T MRI can better track cortical brain lesions and play a crucial role in evaluating the progression of multiple sclerosis (MS), but some experts aren't sure it is clinically feasible.
