Riverain brings Deus lung CAD to market

While most of the attention on computer-aided detection technology has been concentrated on mammography or lung CT, CAD firm Riverain Medical is focusing on chest radiographs. Originally developed by Deus Technologies, the RapidScreen system can help radiologists detect more lung cancers, as well as identify precancerous nodules.

3D MRI technique helps plan treatment for pediatric heart conditions

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Could AI scoring help with managing DCIS?

Ultrasound model predicts liver disease progress

By Amerigo Allegretto

A predictive model combining multiple ultrasonic parameters can discriminate between different liver diseases.

March 20, 2024

Multiparametric ultrasound in a 52-year-old female patient with metabolic dysfunction-associated fatty liver disease (MAFLD) and hepatitis B, whose body mass index was 26.9. (A) Gray-scale image (left) shows the liver parenchyma, and attenuation image (right) shows the right liver lobe acquired from the right intercostal oblique plane, with the degree of attenuation color-coded in the sampling box. Orange indicates a high attenuation coefficient and blue indicates a low attenuation coefficient. The coefficient value (0.59 dB/cm/MHz) and reliability index (R2 = 0.95) are presented in the lower left corner. (B) 2D shear-wave elastography-generated quad-view mode image shows an elasticity map, propagation map, gray-scale image, and dispersion map at the same time. A 1-cm region of interest is placed within the sampling box of each image. Red and blue indicate high and low elasticity and dispersion slope, respectively. Liver stiffness on the elasticity map is 5.6 kPa, and the dispersion slope on the dispersion map is 13.23 (m/sec)/kHz. Image courtesy of the RSNA.

CTPA rates increase among pregnant women

By Kate Madden Yee

The use rate of CT pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism has increased among pregnant women -- but outcomes from these studies are often negative, researchers have reported.

FAPI-PET/CT outperforms FDG-PET/CT in women with invasive breast cancer

PET/CT imaging using gallium-68 FAPI radiotracer over F-18 FDG appears promising in women with invasive lobular carcinoma.

Maximum-intensity projection F-18 FDG-PET (left) and Ga-68 FAPI-PET (right) images of synchronous ILC. (A) A 42-year-old patient with multicentric primary lesions (encircled), regional (solid arrows), and distant inferior jugular lymph node (dashed arrows) seen on F-18 FDG-PET and subsequently confirmed on Ga-68 FAPI-PET, which also revealed additional malignant foci aligned with MRI. Some lesions exhibited high activity retention on Ga-68 FAPI-PET. (B) A 53-year-old patient showing no significant uptake on F-18 FDG-PET but synchronous bilateral lesions (arrows) on Ga-68 FAPI-PET, which also identified pathologic lymph nodes (encircled), resulting in upstaging.

Image perception: Are radiologists akin to MLB batters?

A radiologist’s perception when viewing a complex MRI may be akin to a Major League Baseball (MLB) batter reading the stitches on a fastball, according to researchers exploring how diagnostic interpretations are made.
