CT

Magnetic resonance imaging offered a 29 percent higher sensitivity than CT for differentiating liver metastases, but CT provided 12 percent higher sensitivity than MRI for assessing vascular invasion, according to a new 40-study meta-analysis.

While better imaging may reduce the need for additional diagnostic tests, it may also eliminate the reimbursement that comes with those additional tests.

In a study involving over 700 participants who had chest CT and brain MRI, those with diabetes and lower vertebral bone mineral density (vBMD) had a nearly five percent faster total accumulation of white matter hyperintensity (WMH) in comparison to those without diabetes.

Emerging research demonstrates the increasing stability of attenuation on clinically relevant VMIs with photon-counting CT and a redefined role of kV that may have implications for longitudinal quantitative CT.

The use of adjunctive AI for pulmonary nodule assessment on chest CT exams led to over a three-minute reduction in median reporting time, according to newly reported research.

In the first of a two-part interview, Kalpana Kanal, PhD, and Mahadevappa Mahesh, MS, PhD, FAPPM, FACR, discussed recently published research showing significant declines in computed tomography (CT) radiation dosing over the past decade.

A new study shows that even small plaque volume may be associated with significantly higher risk for cardiovascular events, making the enhanced spatial resolution available with advanced imaging even more critical in risk stratification.

In comparison to contrast-enhanced CT, FAPI PET was associated with over 27 percent higher sensitivity for peritoneal carcinomatosis in the small bowel and 53 percent higher sensitivity in the upper abdomen, according to a new study involving 200 women with primary ovarian carcinoma.

New research suggests that photon-counting CT provides comparable sensitivity to breast MRI for lesion characterization, higher accuracy than MRI for nodal metastasis and lower detection of microcalcifications in comparison to full-field digital mammography.

Elevated coronary inflammation, measured with the CCTA-derived and AI-enabled perivascular fat attenuation index (FAI) score, was associated with over a 12-fold higher risk for cardiovascular mortality in patients with no diabetes, hypertension, smoking history or obesity, according to new research presented at the European Society of Cardiology (ESC) Congress.

New research presented at the European Society of Cardiology (ESC) conference demonstrates that fractional flow reserve (FFR) based off CCTA exams significantly decreases unnecessary invasive coronary angiography (ICA) procedures for patients with stable chest pain and obstructive stenosis.

In a recent interview, Arun Talkad, MD, discussed the use of AI-powered enterprise imaging to facilitate recently expanded acute stroke care guidelines from the American Heart Association and the American Stroke Association.

In addition to providing stronger image quality, well-designed photon-counting CT systems may facilitate increased standardization, efficiency and simplification that may lead to reduced cognitive burden for radiologists.

Reducing false positives in evaluation of muscle invasion in bladder cancer cases that can occur with conventional imaging, spectral information with photon-counting CT may offer significantly improved accuracy and specificity in local staging.
