MSCT boosts diagnosis of perforated appendix
Japanese researchers have found that detection of an enhancement defect of the appendiceal wall using multislice CT allows accurate diagnosis of perforations of the inflamed appendix.
Dr. Masahiro Tsuboi and colleagues at the Tohoku University in Miyagi retrospectively evaluated 102 patients with confirmed appendicitis. The investigators found that contrast-enhanced MSCT was able to spot appendix perforations accurately in 38 of 40 patients confirmed with perforated appendicitis based on a particular enhancement defect of the appendiceal wall. Sensitivity, specificity, and accuracy were all above 95%. Researchers published their results in the January issue of Radiology (2008;246:142-147).
Considering Breast- and Lesion-Level Assessments with Mammography AI: What New Research Reveals
June 27th 2025While there was a decline of AUC for mammography AI software from breast-level assessments to lesion-level evaluation, the authors of a new study, involving 1,200 women, found that AI offered over a seven percent higher AUC for lesion-level interpretation in comparison to unassisted expert readers.
