Lesion size and morphology at VC good predictors of histology

Size and morphology are good predictors of whether a colorectal lesion harbors advanced histology and needs to be removed, according to a new multicenter study from Italy. The results suggest that polyps of the same size detected at virtual colonoscopy could be classified and managed differently based on their morphology.

MRI shows age- and gender-based differences in myocardial motion

People who suspect that men's and women's hearts march to different drummers now have proof from cardiac MRI. Myocardial motion is strongly influenced by gender as well as age, according to researchers from Freiburg, Germany.

CAD catches most flat polyps on virtual colonoscopy

Computer-aided detection (CAD) is sensitive for all but the flattest of flat colorectal lesions, even in minimally prepped patients, according to a new study from Italy. Using CAD, radiologists significantly improved their ability to detect the elusive polyps, which can harbor precancerous lesions.

Coronary CTA edges CMR in a tight race

CHICAGO - In a head-to-head comparison of two closely watched modalities, low-dose dual-source coronary CT angiography (CTA) outperformed cardiac MR (CMR) in sensitivity, specificity, and negative predictive value. But 1.5-tesla CMR countered with better specificity and positive predictive value.

Surveillance polyps show little growth at follow-up

CHICAGO - A preliminary study from Italy adds weight to the argument that two- to three-year surveillance of 6- to 9-mm polyps doesn't unduly increase the risk of colorectal cancers. Diminutive polyps grow faster but present less cause for concern.

Meta-analysis reveals paucity of advanced neoplasia in small polyps

The prevalence of advanced neoplasia in subcentimeter polyps is extremely rare, according to a new meta-analysis of virtual colonoscopy data from more than 20,000 patients. As a result, the study authors believe that it's unnecessary to incur the costs and risks associated with resecting diminutive colorectal lesions detected at VC.

Ignoring breast CAD detections cuts sensitivity

Computer-aided detection (CAD) is effective at finding breast cancers -- including lesions that would have otherwise been missed by experienced radiologists. Unfortunately, CAD's overall benefit is diluted by the downside of radiologists ignoring true-positive CAD marks.

VC excels at diverticulosis staging

Although virtual colonoscopy practice has always focused on adenoma detection and colon cancer prevention, the exam is proving to be formidable in the staging of diverticular disease, a scourge of fast-food Western nations that affects most of their citizens by age 60.

Fat-fluid levels sign: T1- and T2-weighted MRI shows cyst with thin septa, heterogeneous content, and fat-fluid levels, which is compatible with fat content, suggestive of galactocele. A cystic mass with a fat-fluid level is a diagnostic indicator of a galactocele, with the fat content above and the water content remaining at the bottom.

PET/CT shows impact of different COVID-19 vaccines

The type of COVID-19 vaccine and the time interval between vaccination and PET/CT scans are key factors in minimizing false interpretations in cancer patients.

December 18, 2023

A 73-year-old woman with a suspicious lung nodule was referred to our division for F-18 FDG PET/CT exam. She was vaccinated four days before PET/CT. The lung nodule did not show any pathological FDG uptake; however, high tracer activity was detected on her right arm, where she was injected, and multiple hypermetabolic lymph nodes in the right axilla (arrows). Moreover, PET/CT showed high tracer activity in the liver (black arrows), spleen (triangular arrows), and bone marrow (small triangular arrows) as the result of systemic immune response after vaccination. The tracer defect in the liver was due to the known cyst. (A) fusion scan, (B) PET, (C) maximum intensity projection. Image courtesy of Scientific Reports.
