New breast imaging algorithm brings breast cancer diagnosis and treatment to underserved area of Uganda
A new breast imaging algorithm is being implemented in Uganda to diagnose and treat women with palpable breast masses. The program combines a unique diagnostic algorithm with targeted community outreach to combat myths surrounding cancer, aiming for early diagnosis and effective care.
ASPB names 2013 awards recipients
The American Society of Plant Biologists (ASPB) recognizes outstanding achievements in plant biology through its 2013 awards. The recipients include Natasha Raikhel for her contributions to protein trafficking and service to the discipline, as well as Robert Turgeon for his work on phloem transport.
MDCT helps better determine valve implant size for transcatheter aortic valve in patients with aortic stenosis
A new study suggests MDCT is more accurate than echocardiography for measuring annular size in TAVI candidates. This improvement can lead to better procedure success and valve selection, potentially changing the decision for 55% of patients.
Tomosynthesis improves detection of infiltrating ductal carcinoma in patients with increased risk
Tomosynthesis surpasses 2D mammography in detecting infiltrating ductal carcinoma, particularly in women at increased risk of breast cancer. The study found that tomosynthesis improved visibility in 41% of cases and identified cancers only visible on tomosynthesis.
Dual energy CT accurately identifies ACL tears in emergency department
A new study shows that dual energy CT is an effective way to evaluate emergency department patients with possible ACL tears. The imaging technique accurately identified ACL tears in 94% of cases, making it a promising alternative to MRI.
Additional imaging gives better view and reduces complications in patients needing gastric tubes
Researchers found that combining fluoroscopy and CT scans reduces major complications during gastric tube insertion by nearly eliminating misplacement errors.
MR images taken during the systole phase improve diagnoses of scars on the heart
New study finds MR images taken during systole phase show more accurate detection of myocardial scars in ischemic cardiomyopathy patients. Systolic images revealed scars not visible on diastolic images, particularly in the left ventricle area prone to ischemic damage.
Decreasing KV reduces radiation dose in lumbar spine CT without compromising quality
A new algorithm optimizes tube potential for patients undergoing lumbar spine CT exams, resulting in a 41% reduction in radiation dose. The study found that lower kilovoltage images maintained diagnostic quality despite increased image noise.
