Multislice computed tomography (MSCT) scanning shows high accuracy in detecting significant lesions and coronary calcifications compared to invasive coronary angiography. MSCT may reduce the likelihood of clinically important CAD in patients with suspected disease, but its use requires proper patient selection and adequate training.
The new Local-Electrode Atom-Probe (LEAP) tomograph allows researchers to study the nanostructure and chemical composition of materials at an unprecedented level. By analyzing the structure and chemical identity of steel, scientists can design stronger materials with improved properties.
A study comparing the relative sensitivity of colonoscopy, ACBE, and CTC found that colonoscopy detected 98% of large and 99% of small lesions, outperforming ACBE and CTC. The results have important implications for clinicians considering colon imaging tests and potentially for colon cancer screening programs.
A study using triple-contrast CT found that it can accurately detect peritoneal damage and injury extent in patients with penetrating torso trauma. The imaging modality achieved an overall accuracy rate of 98 percent, surpassing previous limitations of CT scans for retroperitoneum assessment.
A study published in JAMA found that computed tomographic colonography (CTC) had lower sensitivity rates compared to conventional colonoscopy for detecting colorectal tumors, raising concerns about its readiness for widespread clinical use.
