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.

MR study exposes physiologic differences in aging bone
Today is World Osteoporosis Day and this year's theme is "Move it or lose it." While activities to raise awareness of the condition are planned around the world, doctors at the Chinese University of Hong Kong have been hard at work learning more about what causes bone density loss to begin with.

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.

Representative examples of visual TAC categories, assessed on chest CT in asymptomatic individuals undergoing general health screening (blue indicates segmented TAC at level of aortic arch). Axial (A) and sagittal volume-rendered (B) images in 42-year-old patient. AI-based quantification yielded TAC volume of 101 mm3 and TAC Agatston score of 105. Examination was assessed as showing visually mild TAC. Axial (C) and sagittal volume-rendered (D) images in 57-year-old patient. AI-based quantification yielded TAC volume of 834 mm3 and TAC Agatston score of 993. Examination was assessed as showing visually moderate TAC. Axial (E) and sagittal volume-rendered (F) images in 65-year-old patient. AI-based quantification yielded TAC volume of 4872 mm3 and TAC Agatston score of 5848. Examination was assessed as showing visually severe TAC. Images and caption courtesy of the AJR.
