FLT-PET shows promise in differentiating unclear lung lesions
FDG has long shown its efficacy in demonstrating the metabolic differences between benign and malignant lung tumors. However, the radiotracer is not tumor-specific. German researchers are investigating fluorothymidine (FLT) as an alternative radiotracer for therapy response in non-small cell lung cancer.

Physicians who diagnose gall bladder dyskinesia will remember 2001 as the year Bristol-Myers Squibb turned off the tap on Kinevac, a synthetic cholecystokinin drug used in cholescintigraphy. A year later, in December 2002, Bracco Diagnostics resumed manufacturing and marketing the product.

For administrators hoping to increase their staff of radiologists, or fill an empty slot in the lineup, finding qualified candidates can be more trouble than a medieval search for the Holy Grail. But unfortunately, there's no Monty Python to provide comic relief to the quest; just endless hours spent tracking down and securing top talent that can vanish like a morning mist.

DR looks good in CR, film comparison study
German researchers recently conducted an observer preference study comparing flat-panel digital radiography to computed radiography and film-screen chest radiography. They found that DR was as good as, or better than, the other technologies for visualizing anatomic structures.

Trial questions PET's cost-effectiveness for Alzheimer's diagnosis
Based on the results of their analysis, Boston researchers concluded that although PET may have a high diagnostic accuracy for Alzheimer’s diagnosis, adding it to the standard diagnostic regimen at Alzheimer’s disease clinics would yield limited benefits at a very high cost.

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 nonmass lesion that was diagnosed as microinvasive ductal carcinoma. (A) Transverse and (B) longitudinal ultrasound images show a hypoechoic nonmass 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 nonmass 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).
