CTA finds lesions missed by catheter angiography
CT angiography can identify patients with subclinical atherosclerosis who may be inaccurately diagnosed as normal by traditional catheter angiography, according to a study at the 2004 North American Society for Cardiac Imaging meeting.
CT angiography can identify patients with subclinical atherosclerosis who may be inaccurately diagnosed as normal by traditional catheter angiography, according to a study at the 2004 North American Society for Cardiac Imaging meeting.
Jeffrey J. Fine and Dr. Richard A. Edelson of the South Carolina Heart Center in Columbia used 16-slice CTA to evaluate 40 consecutive patients within seven days after they had a normal diagnostic catheterization.
CTA identified eight patients with nonobstructive blockages in the left anterior descending artery (75% were calcific lesions and 25% soft plaque). Additionally, two of those eight had nonobstructive calcific blockages in the circumflex artery, and four had nonobstructive calcific blockages in the right coronary artery.
Although catheter angiography is the standard of reference for diagnostic angiography, it produces a 2D image with limited outer vessel visualization, preventing the identification of specific lesion types, Fine said.
Seven Takeaways from Meta-Analysis of PSMA Radiotracers for Prostate Cancer Imaging
December 1st 2023In a newly published meta-analysis of 24 studies, researchers noted that the PSMA PET radiotracer 18F PSMA-1007 may provide more benefit than 68Ga Ga-PSMA-11 for primary staging of patients with prostate cancer and detection of local lesion recurrence, but also has drawbacks with higher liver uptake and multiple reports of false positive bone lesions.
Study: Regular Mammography Screening Reduces Breast Cancer Mortality Risk by More than 70 Percent
November 30th 2023Consistent adherence to the five most recent mammography screenings prior to a breast cancer diagnosis reduced breast cancer death risk by 72 percent in comparison to women who did not have the mammography screening, according to new research findings presented at the annual Radiological Society of North America (RSNA) conference.
