RSNA studies advance ultrasound's role in breast cancer detection

The preliminary results of the ACRIN 6666 trial show that ultrasound boosts cancer detection but at the risk of a higher false-positive rate. While the trial investigators continue to mine the trial data to find the best place for the modality in a screening setting, other researchers are using advanced imaging technology such as 3D and computer-aided analysis tools with ultrasound to enhance breast imaging.

Catching undetected cancer with MR plus mammo in high-risk women outweighs costs

SAN ANTONIO - The American Cancer Society has given its stamp of approval to mammography plus MRI screening in women with a higher risk for breast cancer, but what's the economic impact of that dual-modality paradigm? The increase in breast cancer detection would justify the high price of the MR exam, although that cost-effectiveness does depend on the specific type of risk a woman carries, according to the authors of a new study.

Elasticity imaging finds breast tumors based on shape, volume

Real-time elasticity imaging can improve the characterization of breast lesions while also serving as a tool to determine if biopsy is necessary, according to a multicenter study presented at the 2007 RSNA meeting in Chicago. The investigators presented an update of the results of a 2006 single-center study on breast elasticity imaging.

CT autopsy comparable to conventional autopsy for blunt trauma deaths

CHICAGO - In a head-to-head comparison with conventional autopsy, CT imaging autopsy was as effective in determining cause of death in accidental blunt trauma cases, according to researchers from the University of Maryland in Baltimore. They presented the findings from their study at the RSNA 2007 meeting.

Computer-aided dental x-ray system quickly identifies victims of mass disasters

CHICAGO - In 1985, it took 2,800 forensic specialists more than three months to identify the remains of the 520 victims in Japan's worst commercial air disaster, the crash of Japan Airlines Flight 123. If an experimental computer-aided dental x-ray system had been available then, the identification process could have been accomplished in about nine days, according to researchers from Japan.

Image-Guided Surgery

US guidance needles away the pain of rotator cuff calcific tendinitis

CHICAGO - A 15-minute, inexpensive procedure using ultrasound guidance and local anesthesia can relieve severe, disabling shoulder pain caused by calcific tendinitis of the rotator cuff, according to physicians from Italy. In a presentation at the RSNA 2007 meeting, they described the details of procedure and reported the results from nearly 2,800 patients who received the treatment.

Rampant U.S. obesity strains imaging devices

CHICAGO - People in the U.S. are getting so heavy that, even though they are most likely to be at risk for major diseases, they may outweigh the ability to be treated. The reason? The patients are too heavy to be accommodated by most standard imaging devices, according to a presentation at this week's RSNA 2007 meeting.

FDG-PET/CT accurately detects inflammatory breast cancer

CHICAGO - The use of FDG-PET/CT with patients with inflammatory breast cancer can accurately detect and help treat the deadly disease, according to a study by researchers at the University of Texas M. D. Anderson Cancer Center in Houston. They presented their findings at the RSNA 2007 meeting on Tuesday.

An example of a typical BgRT plan: A) PET scan on diagnostic PET/CT and B) X1 PET-Linac for patient #15 with a PET avid rib metastasis with GTV size= 3.1 cc, PTV = GTV + 5mm, BTZ (biological tracking zone) = PTV + 5 mm, AC = 14.33 kBq/mL and NTS = 21.04. Red, magenta, and green contours represent GTV, PTV, and BTZ. C) Dose distribution and D) bounded-DVH of a BgRT plan are displayed for the same patient. The bounded Dose-Volume Histogram (DVH) models variations in BgRT delivery, encompassing fluctuation in target background signal variation, target localization and dose delivery uncertainties.

Is it time to ditch physical exams before ultrasound?

By Amerigo Allegretto

Physical exams are omitted in over half of patient cases, and it seems diagnostic outcomes are unaffected.

AI model detects achalasia on chest x-rays

Currently, few noninvasive tests are available for diagnosing the swallowing condition.

September 18, 2025

Saliency maps using Grad-CAM++ (E and H) show the model’s point of interest in chest radiographs (C and F) of patients with achalasia. The model’s point of interest is highlighted with red, yellow, and green. In both the upper and lower panels (E and H), the point of interest is located in a region around the upper esophagus that corresponds to an air esophagogram and/or air-fluid level in the esophagus in the barium esophagogram (D and G).

Echogenic rind on breast ultrasound holds diagnostic significance

By Amerigo Allegretto

An echogenic rind on breast ultrasound could spell malignancy for suspicious lesions.

September 17, 2025

Diagnostic transverse ultrasound image of the left breast in a 64-year-old woman shows irregular hypoechoic nonparallel mass with indistinct margins corresponding to palpable finding, assessed as BI-RADS category 4. Both readers assessed mass as having associated echogenic rind with complete circumferential extent (arrowheads). Ultrasound-guided biopsy of mass yielded diagnosis of invasive ductal carcinoma (intermediate grade, luminal A molecular subtype, no lymphovascular invasion).
