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.

Color-coded tagging software speeds VC interpretation
A novel color-coded fecal-tagging method significantly cut interpretation time for reduced-prep virtual colonoscopy in a recent study, easing a task that can be tiring and time-consuming for radiologists.

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.

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).

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.

Images obtained in a 50-year-old female patient with a new biopsy-proven malignant lesion in the left breast. (A) Craniocaudal mammogram of the right breast does not show any lesion. (B) The malignant lesion corresponds with a 7-cm irregular and spiculated mass on the left craniocaudal mammogram. Ultrasound-guided core-needle biopsy revealed grade 2 invasive lobular carcinoma. (C) The bilateral positron emission mammographic craniocaudal color image obtained one hour after intravenous injection of 185 MBq of F-18-labeled fluorodeoxyglucose (F-18 FDG) shows a mass with intense uptake in the left breast with known cancer and no abnormal uptake in the right breast. Positron emission mammographic craniocaudal images of the left breast obtained (D) one hour and (E) four hours after intravenous injection of 185 MBq of F-18 FDG show no substantial visual difference in uptake of the known cancer. (F) Axial contrast-enhanced fat-saturated subtracted T1-weighted MR image with maximum intensity projection reconstruction obtained 90 seconds after intravenous injection of 0.1 mmol of gadolinium-based contrast material per kilogram of body weight also shows the enhancing mass corresponding to known malignancy (arrow) and marked bilateral background parenchymal enhancement, with multiple nonspecific foci of enhancement in the contralateral breast. The patient opted for bilateral mastectomy, which confirmed left-sided malignancy and no malignancy in the contralateral breast. Image courtesy of the RSNA,
