Did Malpractice Risk Kill V/Q Exams? October 14, 2024
CT perfusion angiography exams have largely replaced nuclear medicine-based ventilation/perfusion (V/Q) studies for detecting pulmonary embolism. But a new article in Academic Radiology suggests that CT’s rise wasn’t entirely based on clinical efficacy – fears of malpractice risk may have played a role. V/Q studies can help diagnose PE by enabling clinicians to visualize lung […]

Low-Dose CT Confounds CAD in Kids October 10, 2024
When it comes to pediatric CT scans, clinicians should make every effort to reduce dose as much as possible. But a new study in AJR indicates that lower CT radiation dose can affect the performance of software tools like computer-aided detection. Initiatives like the Image Wisely and Image Gently projects have succeeded in raising awareness […]

Mammography AI Predicts Cancer Before It’s Detected October 7, 2024
A new study highlights the predictive power of AI for mammography screening – before cancers are even detected. Researchers in a study JAMA Network Open found that risk scores generated by Lunit’s Insight MMG algorithm predicted which women would develop breast cancer – years before radiologists found it on mammograms. Mammography image analysis has always […]

Breast Cancer Mortality Falls Again October 3, 2024
New data from the American Cancer Society highlight the remarkable strides that have been made against breast cancer, with the U.S. death rate falling 44% over the last 33 years – saving over half a million lives. But the statistics also underscore the work that remains to be done, particularly with minority women. The fight […]

The Cost of Extra Cancer Detection September 30, 2024
It’s well known that using additional screening modalities beyond traditional 2D mammography can detect more cancers in women with dense breast tissue. But at what cost? A new study in Clinical Breast Cancer documents both the clinical value and the economic cost of supplemental breast imaging technologies. 2D mammography is the basis for any breast […]

MRI Reduces Prostate Biopsies September 26, 2024
New research provides additional support for MRI’s role in making prostate screening more effective. In a new study in NEJM, researchers found that MRI can help reduce unnecessary biopsies more than 50%, with a very low chance of missing high-risk disease. As we’ve discussed in previous newsletters, prostate cancer screening based on PSA levels is […]

AI Recon Cuts CT Radiation Dose September 23, 2024
Artificial intelligence got its start in radiology as a tool to help medical image interpretation, but much of AI’s recent progress is in data reconstruction: improving images before radiologists even get to see them. Two new studies underscore the potential of AI-based reconstruction to reduce CT radiation dose while preserving image quality. Radiology vendors and […]

U.K.’s Massive Diagnostic IT Project September 19, 2024
The U.K. is planning a massive project – worth close to $1B – to procure new IT tools for medical diagnostic use. While details of the plan are still sketchy, it involves the acquisition of both radiology and cardiology PACS, as well as AI. The U.K.’s NHS has become one of the world’s hottest test […]

Combo CT Screening Detects More Disease September 15, 2024
A CT lung cancer screening program that also offered abdominal non-contrast CT scans detected a large number of abnormalities outside the lung in a population of people with smoking histories. The combined approach could offer a more efficient way to detect multiple pathologies in a single patient visit. CT lung cancer screening is gaining momentum […]

Why the FDA’s Density Rule Matters September 12, 2024
The FDA’s new rules on reporting breast density to women getting mammograms went into effect on September 10. The implementation has been expected for some time, but this week’s rollout generated a wave of positive press coverage that highlights the importance both of breast density awareness and of breast screening. The FDA in March 2023 […]
