Study suggests ways to cut CR radiation

A new study by Australian researchers has found that the radiation dose delivered in computed radiography (CR) examinations could be cut in half by adjusting the manufacturers recommended range (MRR) for exposure indices (EIs) by as little as 10%.

MR proves accurate and comfortable for colon imaging

Dr. Jörg Debatin from the University Hospital Essen in Germany said the two most important qualities of any screening test are diagnostic accuracy and patient acceptance -- requirements that MR colonography appears to fulfill. The procedure has been shown to be accurate for the detection of clinically relevant colonic polyps larger than 10 mm.

Intervention can help or harm in athletic injuries

Ultrasound can diagnose and treat a wide range of athletic injuries, including tendinopathy, post-traumatic synovitis, impingement syndromes, and back pain. With intervention, however, extreme care must be taken to avoid exacerbating the problem.

Ultrasound has unique strengths in breast imaging

The primary role of ultrasound in breast imaging is to differentiate cystic from solid lesions. The modality can also be used to confirm a suspected or palpable mass, as an aid to treatment planning, and for needle guidance in interventional procedures. Dr. Debra Ikeda from Stanford University offers tips for performing breast ultrasound.

Tamoxifen confuses uterine appearance on ultrasound

The unusual ultrasound appearance of the uterus in women receiving tamoxifen citrate can be misinterpreted as endometrial thickening. This confusing appearance is due to microcystic change in the proximal myometrium of the uterus, according to a presentation at the 2001 International Society of Ultrasound in Obstetrics and Gynecology world congress in Melbourne, Australia.

Adenomyosis: Making the diagnosis with ultrasound

Many women who present for ultrasound examination with abnormal premenopausal vaginal bleeding may have adenomyosis, a benign disease of the uterus in which endometrial glands and stroma are found within the myometrium, according to a presentation at the 2001 Australian Society for Ultrasound in Medicine meeting.

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).
