Open-source software increases colon polyp conspicuity

Visibility of colon polyps is increased and sensitivity improved with the use of threshold-based color-coding software in virtual colonoscopy, according to a new study from Italy. Even flat lesions were more often visible with use of the open-source 2D-based interpretation software.

Cardiac cath delivers high radiation doses to operators

The rapid development of new cardiac stents and other medical devices is opening up a world of possibilities for interventional procedures in the cath lab -- but it's also exposing equipment operators to ever-higher radiation doses.

Blood infection risk extremely low with VC

The risk of bloodstream infections such as bacteremia leading to endocarditis is extremely low in virtual colonoscopy -- in fact, infection rates are probably even lower than in conventional colonoscopy, say researchers from Ireland, the U.K., and the U.S.

DSCT beats other methods for noninvasive gout diagnosis

Dual-source CT (DSCT) can reliably diagnose gout in its preclinical stages, opening the door to noninvasive diagnosis and earlier, more effective treatment, according to an article published in the April issue of the American Journal of Roentgenology.

Heart rate key to image quality in low-dose coronary CTA

Heart rate control is an important factor for success in prospectively gated coronary CT angiography (CTA). But once patients are beta-blocked, the success rate is high and the doses are uniformly low, according to a new study by Swiss researchers.

Diverticular disease favors prone over supine VC images

Diverticular disease, an unfortunate result of low-fiber Western diets that increases in incidence with age to burden most of the elderly population, has a friend in virtual colonoscopy. That's because VC generally provides an easier colon exam for both patient and provider than conventional colonoscopy.

Massive VC study yields trove of extracolonic cancers

A study of more than 10,000 asymptomatic screening subjects found that more than one in 200 had unsuspected and typically large but mostly early-stage cancers detected outside the colon at virtual colonoscopy.

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.
