Trump administration hits brakes on law to curb unneeded Medicare CT scans, MRIs

The U.S. Congress passed a law in 2014 to reduce unnecessary MRI exams, CT scans, and other expensive diagnostic imaging tests, but the Trump administration delayed putting the law into effect until 2020 after physicians argued it would interfere with their practices. Critics worry the delay comes at a cost: Medicare paying for millions of unnecessary exams and patients subject to unnecessary radiation.

Could cranial ultrasound sub for brain MRI in imaging infants?

Cranial ultrasound could have utility for imaging infants with hypoxic-ischemic encephalopathy.

Lateral conventional attenuation (a, b, e, f) and co-registered dark-field (c, d, g, h) images of two spine specimens. Vertical (a, c, e, g) and horizontal (b, d, f, h) scans of the spine specimen of a 77-year-old female with osteoporosis (bone mineral density = 65.75 mg/dL) (a–d) and a non-osteoporotic spine specimen (e–h) of a 61-year-old female (bone mineral density = 169.38 mg/dL).

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).
