MRI continues to make headway in breast cancer imaging

MRI has proved to be highly sensitive for detecting breast cancer, but it continues to suffer from poor specificity and frequent false positives. Breast imaging experts, however, keep striving for improvements with MRI, and a series of recent studies highlights the advancements that MRI has made in breast imaging.

Revamping residency hours could carry a significant price tag

In 2003 the Accreditation Council for Graduate Medical Education (ACGME) limited residents to an 80-hour work week to address multiple issues, such as the reduction of medical errors. But what degree of decline in adverse events would be needed to make reform less of a financial burden on hospitals and society? Researchers from California sought the answer by performing a cost analysis using four possible reform strategies.

MR features delineate invasive breast cancer in lactating women

Pregnancy-associated breast cancer is often found at an advanced stage, partly because of decreased mammographic sensitivity in the lactating breast. A report released today in Radiology describes how MRI can cut through the increased parenchymal density, glandular volume, and water content of the lactating breast.

Scintimammography-SPECT valid as secondary test for ambiguous breast cancer

Thus far, scintimammography's value has been proved in women with dense breasts or those who have breast cancer recurrence. Now researchers from Belgium have studied the impact of scintimammography in a clinical setting for women with inconclusive or contradictory results on routine breast imaging workup.

US-guided optical breast imaging separates benign from malignant tumors

When paired with other modalities, breast ultrasound can reduce the need for biopsy, but imaging lesions with sonography alone may not be reliable enough to completely bypass the procedure. By the same token, optical tomography reveals vital information on tumor angiogenesis and hypoxia, but imaging resolution is limited by technical issues. The combination of the two modalities may be the ticket to differentiating benign and malignant breast masses.

Panoramic x-rays prove suitable for dental age calculation

In the mid-90s, Dr. Sigrid Kvaal and colleagues in Oslo, Norway, proposed x-ray as a noninvasive way to estimate the age of adults in forensic work and archaeological studies. More recently, a group from the Katholieke Universiteit in Leuven, Belgium, tested Kvaal's dental age calculation technique on panoramic dental radiographs.

Low-dose CT ties emphysema to mortality in previous smokers

By Amerigo Allegretto

Study findings highlight the clinical relevance of CT-diagnosed emphysema.

September 9, 2025

Representative axial images of mild, moderate, and severe emphysema at baseline low-dose CT (LDCT). Participants were categorized as having no emphysema or mild, moderate, or severe emphysema. When present, emphysema was mild if no distinct regions of reduced attenuation were visible on the CT scan, but vascular splaying indicates parenchymal expansion, or if only occasional discrete low-attenuation regions were observed. Moderate emphysema was defined by the presence of identifiable low-attenuation regions affecting less than half of the lung parenchyma, whereas severe emphysema was defined by the presence of identifiable low-attenuation regions that involved more than half of the lung parenchyma. A scoring system from 0 to 3 was applied, corresponding to none, mild, moderate, and severe emphysema, respectively. Yellow circle indicates the extent of emphysema. (A) A 67-year-old man with mild emphysema at baseline LDCT in 2002. Baseline LDCT scan shows vascular splaying, suggesting parenchymal expansion due to emphysema and occasional discrete low-attenuation regions. The participant ultimately died of cardiovascular disease 15.4 years (184.2 months) later. (B) A 69-year-old man with moderate emphysema at baseline LDCT in 2007. The participant died of cardiovascular disease 1.8 years (21.9 months) later. Identifiable low-attenuation regions affected less than half of the lung parenchyma. (C) An 85-year-old woman with severe emphysema at baseline LDCT in 2006. After 5.5 years (65.5 months) of follow-up, the participant died due to chronic obstructive pulmonary disease–related causes. Identifiable low-attenuation regions involved more than half of the lung parenchyma.
