Radiation dose in women's imaging: Are we scared yet?
Major reductions have been made in mammography radiation dose over the past 16 years, thanks to technological innovation and national quality standards. Despite this progress, many public health advocates -- as well as women of screening age -- are more worried about dose than ever.

Las mujeres con senos densos tienen alto riesgo del cáncer recurrente
Un nuevo estudio difundido en noviembre en la publicación Cancer encuentra que pacientes de cáncer de mama con senos densos tienen un riesgo cuatro veces más alto de malignidad recurrente que las mujeres con senos menos densos. Pacientes con tejido denso podrían ser dirigidos a terapia por radiación por sus elevados niveles de riesgo, sugiere el estudio.

Women with dense breasts have higher risk of recurring cancer
A new study published online today in Cancer has found that breast cancer patients with dense breasts have a four times higher risk of recurring malignancy than women with less-dense breasts. Patients with dense breast tissue might be directed to radiation therapy due to their elevated risk levels, the study suggests.

Radiology rallies to fight more reimbursement cuts
It's do or die for radiology as the specialty struggles to fend off proposals in the U.S. Congress mandating severe cuts in reimbursement. Radiology proponents are predicting economic Armageddon if the cuts are passed, but their arguments may not be strong enough to counter the powerful forces of healthcare reform.

Nyaya Health brings ultrasound expertise to Nepal
In the mountains of the Achham district in rural Nepal, a five-room, four-bed medical clinic bustles on the spot where once only the wind whistled through an old grain shed. In this remote location, high-tech medical imaging technology combined with satellite telecommunications is improving the quality of healthcare to residents.

Cardiac cath lab procedures fall 11% over past 2 years
Total patient cases accommodated by U.S. cath labs declined to 3.75 million in 2008, an 11% drop from 4.21 million in 2006, according to a report by market research firm IMV Medical Information Division. This is in contrast to IMV's 2006 report, which identified a gradual 9% increase in patient cases from 3.85 million in 2002.

Ultrasound nonmass breast lesion features may signal malignancy
By Amerigo Allegretto
Some nonmass breast lesion characteristics on ultrasound exams can be considered suspicious for malignancy at screening ultrasound.
November 5, 2024
Images depict a 43-year-old woman with a malignant non-mass lesion that was diagnosed as microinvasive ductal carcinoma. (A) Transverse and (B) longitudinal ultrasound images show a hypoechoic non-mass lesion (solid arrows) with segmental distribution in the left breast. The lesion has associated calcifications (dashed arrows in A). (C) Longitudinal color Doppler ultrasound image shows high vascularity. (D) Magnified image in the mediolateral oblique view from screening mammography shows grouped calcifications (arrows), which are considered a mammographic correlate of the ultrasound-detected non-mass lesion (A radiopaque marker attached to the skin is visible in the image because the mammographic exam was performed after screening breast ultrasound). Ultrasound-guided core needle biopsy and pathologic examination revealed ductal carcinoma in situ, but the lesion was upgraded to microinvasive ductal carcinoma at subsequent surgery (2.5-cm ductal carcinoma in situ, histologic grade II, estrogen receptor-positive, progesterone receptor-positive, human epidermal growth factor receptor type 2-negative).
