Wider 3D viewing angle may aid polyp detection
Virtual colonoscopy readers saw a greater percentage of the colonic mucosa by increasing the field-of-view on their 3D software to match that of a standard colonoscope. However, the wider viewing angle may have also reduced polyp conspicuity and increased distortion, with unknown effects on detection sensitivity.

Sodium bicarbonate doesn't prevent CIN reactions
For clinicians hoping to prevent contrast-induced nephropathy (CIN) in patients with impaired kidney function, sodium bicarbonate is starting to lose its fizz, according to research published this week in the Journal of the American Medical Association.

CT techniques reveal subtle renal lesions
It's not difficult to miss renal lesions at CT, considering the diminutive size and radiographic subtlety of some lesions. But the right imaging techniques can help ensure that perceptual errors don't get in the way of the diagnosis.

ROI changes colorectal tumor perfusion measurements
The development of automated perfusion-mapping software for CT data has opened up intriguing possibilities for the assessment of tumor vascularity, specifically for monitoring response to antiangiogenic drug treatment. But where, precisely, to measure tumor vascularity is a question that had not been addressed, according to U.K. researchers.

Automated polyp measurement supports risk assessment
Automated polyp-measurement software performed as well as human readers in a study that could lead to more efficient screening with virtual colonoscopy. The study sought to evaluate the accuracy of an automated polyp size measurement tool and its effectiveness for risk stratification in 305 subjects.

A true positive case in a 72-year-old male with a granuloma on chest x-ray after visiting the neurology outpatient clinic for memory disturbance. A small lung nodule was detected in the left-middle to lower lung field by AI software, with an abnormality score of 26%. Co-existing fibrosis was suspected in the apex of bilateral upper lungs, with an abnormality score of 76%. Image courtesy of Scientific Reports.

CEM comparable to MRI in asymptomatic women
By Amerigo Allegretto
Contrast-enhanced mammography (CEM) is on par with MRI in breast cancer screening for asymptomatic women, according to recent research.
November 15, 2023
A 47-year-old female participant with a suspicious mass noted at screening tomosynthesis and subsequent diagnostic ultrasound was recruited for contrast-enhanced mammography (CEM) and MRI. (A) No abnormality was noted on the conventional 2D mammogram showing dense breast tissue. A mass (arrows) was clearly observed on (B) the recombined CEM image and (C) the MRI scan. Both images show marked background parenchymal enhancement. Biopsy confirmed a 1.1-cm grade 2 invasive ductal carcinoma (estrogen receptor- and progesterone receptor-positive, human epidermal growth factor receptor 2-negative). Image courtesy of Radiology.
