VC's extracolonic findings lend an edge in cost-effectiveness

When the benefits of incidental findings outside the colon are included, virtual colonoscopy is more cost-effective than conventional colonoscopy, according to the results of a model-based analysis published Monday in the Archives of Internal Medicine.

Higher CT values associated with malignancy in lung nodules

Dutch researchers noticed some intriguing results in a recent analysis of data from the ongoing NELSON lung cancer screening trial. They found that malignant nodules, scanned at baseline and follow-up, had higher attenuation overall than benign nodules -- a feature that could potentially aid the management of patients with indeterminate solid pulmonary nodules.

Korean VC program sees Western-style success

With virtual colonoscopy capacity concentrated in the U.S. and Europe, programs to screen Asian populations less invasively for colon cancer have been rare. But Korean researchers say they've duplicated Western screening procedures in a technically advanced program that has examined more than 1,000 asymptomatic patients so far.

First 320-slice coronary CTA study shows high image quality

Image quality was excellent and radiation doses generally low in the first peer-reviewed study of coronary CT angiography (CTA) performed on a 320-slice scanner, which can image the heart in a single beat for most patients, according to researchers from Brigham and Women's Hospital in Boston. They retrospectively studied 40 patients who underwent coronary CTA on a 320-detector-row scanner.

Canadian CT lung screening tracks asbestos workers

As the debate swirls in the U.S. over CT lung screening of smokers, Canadian researchers are developing a unique CT screening program designed to focus on patients who have been exposed to asbestos as a tool for early detection of malignant mesothelioma. The investigators aim to help patients while advancing the understanding of mesothelioma, especially early-stage disease, which is poorly understood.

Cardiac CT saves money and time as first-line heart test

Two studies presented on Monday at the 2008 American College of Cardiology (ACC) meeting in Chicago are emblematic of a new wave of evidence supporting the first-line use of CT in subjects with and without suspected heart disease. The first study examined the use of cardiac CT as a gateway to cardiac catheterization in asymptomatic patients, while the second studied the integration of coronary CT angiography into an office-based cardiology practice.

Can ictal SPECT make a comeback in epilepsy patients?

A feasibility study could revive interest in SPECT seizure imaging to help neurosurgeons guide brain surgery in epilepsy patients.

January 16, 2024

Schematic of triggered ictal SPECT and data processing. (A) Previously screened and selected sEEG bipolar contact is stimulated to trigger patient-typical seizure. Directly after seizure onset, confirmed through sEEG signals and semiology, systemic bolus of radiotracer (Tc-99m HMPAO) is administered. Planned SPECT is acquired within less than one hour. (B) Raw data processing from left to right (dataset from participant three as example). Postimplantation CT and preimplantation T1-weighted MRI are coregistered for sEEG lead localization. Raw SPECT images are coregistered to T1-weighted MRI sequence. SPECT deviation map is computed and anatomically colocalized with sEEG signals. Image courtesy of the Journal of Nuclear Medicine.
