DSCT matches angiography for stenosis detection -- even in fast hearts

Dual-source CT (DSCT) offers diagnostic accuracy comparable to that of invasive coronary angiography when it comes to identifying significant coronary artery stenoses, according to researchers from Germany. To test whether DSCT could match angiography in accuracy, they examined patients with suspected coronary artery disease and found DSCT angiography offered high sensitivity for detecting stenosis.

256-slice perfusion CT equivalent to SPECT for arteriosclerosis detection

A prototype 256-slice multidetector-row CT (MDCT) scanner may be just as accurate as SPECT imaging for detecting atherosclerotic obstructions, according to data presented last week at the 2007 scientific sessions of the American Heart Association (AHA) in Orlando, FL.

MDCT may trump whole-heart cardiac MR for detecting stenosis

ORLANDO, FL - In a head-to-head comparison, multidetector-row CT (MDCT) appears to trump whole-heart magnetic resonance (WH-MR) when it comes to detecting coronary artery stenosis, according to researchers from Belgium. They presented their findings at this week's 2007 scientific sessions of the American Heart Association (AHA).

Tibial-talar ratio on x-ray reliably shows ankle alignment

Chronic conditions such as osteoarthritis make it more important to assess the anteroposterior alignment of the ankle, yet more difficult to obtain the needed radiographs. To overcome the inherent challenges, a new study recommends looking at the tibial-talar (TT) ratio.

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).
