VC accreditation goals just a beginning

Virtual colonoscopy accreditation by the American College of Radiology is in the works. Accreditation establishes practice standards and ensures that radiologists meet minimum compliance levels, but is it enough? For better performance and consistent results, best practices need to be defined at every level of care.

MDCT maybe equivalent to MRI, tops echo and SPECT for heart function

Analyzing left ventricular function is the prelude to treating several cardiac diseases, and it seems that multidetector CT may now be equivalent to MRI for the task over a wide range of heart rates, according to researchers from Kyoto University Graduate School of Medicine in Japan. But another study gives MRI a slight edge still.

Training key to VC performance, but how much is anyone's guess

Poor results from some recent trials have cast doubts on virtual colonoscopy's diagnostic capabilities, and placed training issues center stage. Leading practitioners are unanimous in their view that special training is required to do VC well, yet no reliable criteria exist to define adequate training.

Do whole-body CT's costs outweigh the benefits?

Weighing in on the issue of whole-body CT, a new study finds that the scans may be an expensive way to extend lives. Researchers from Boston estimated a cost of $151,000 for each additional year of life gained from the scans, while critics bashed the methodology.

CT venography plus CTPA finds more pulmonary embolism

Pulmonary embolism isn't ruled out nearly as often when indirect CT venography is added to standard CT pulmonary angiography, according to radiologists from New York City. Their study found that the combined imaging approach increased the detection of thromboembolic disease detection by 20% compared with CT pulmonary angiography alone.

Iodine tagging regimen yields best VC results

Tagging agents and protocols are becoming important issues in virtual colonoscopy today, as researchers seek to eliminate the discomfort of cathartic bowel cleansing, and perhaps improve compliance rates for colorectal cancer screening. Researchers from Massachusetts General Hospital evaluated 11 different prep combinations, and found some surprising results.

Ultrasound finds contrast extravasation in ER patients, CT confirms it

In a study with important implications for patients in emergency rooms, Italian researchers have shown that contrast extravasation can be readily seen on contrast-enhanced ultrasound. CT confirmed the findings in most of the patients.

Debate over 2D versus 3D VC reveals subtle differences

Virtual colonoscopy studies presented at the 2004 RSNA meeting showed some intriguing differences between 2D and 3D primary interpretation of CT datasets. Primary 2D interpretation was generally faster, for example, but 3D seemed to pick up a few more abnormalities, both true- and false-positive.

CT tracks renal cancer recurrence after surgery

Cancer recurs in more than a fifth of patients who undergo resection for renal cell carcinoma (RCC), according to radiologists from South Korea. The most common recurrence site is the lungs, according to the researchers, who developed CT guidelines for detecting recurrent RCC based on a multiyear follow-up study of their own patients.

Imaging turnaround times continued to climb in 2024

The largest increases were found in ultrasound and x-ray.

(A) Free-response receiver operating characteristic (FROC) curve for DBT-DINO and DINOv2 (Meta AI) on the detection task. DINOv2 achieved higher sensitivity than DBT-DINO across most false-positive thresholds. (B) Detection rates of DBT-DINO and DINOv2 for lesions that were ultimately found to be benign (n = 70) and lesions that were found to be cancerous (n = 66). Error bars represent 95% CIs estimated via patient-level bootstrapping with 1000 repetitions. Both models showed similar detection rates for cancerous lesions, whereas DINOv2 detected more benign lesions than DBT-DINO. (C) Example bounding box predictions for DBT-DINO and DINOv2 on the detection test set. Each image is a single two-dimensional section from a three-dimensional digital breast tomosynthesis volume; the first column shows a mediolateral oblique view, and the second and third columns show craniocaudal views. Both models struggled to detect very small lesions, such as the 3-mm-diameter lesion shown in the first column. FP = false positive.
