Krypton replaces xenon for patient-friendly ventilation lung scan
Tuesday, November 29 | 10:40 a.m.-10:50 a.m. | SSG03-02 | Room S504ABVentilation lung scans with high-resolution CT can be used to examine lung morphology and function in patients with chronic obstructive pulmonary disease. Replacing xenon with stable krypton gas might make the procedure easier for patients to complete, according to a new study.

Dual-energy measurements aid electronic cleansing in VC
Tuesday, November 29 | 10:30 a.m.-10:40 a.m. | SSG13-01 | Room S403AA study of dual-energy index values at the boundary between colonic mucosa and air found significant enough differences between components of the bowel lumen to develop new virtual colonoscopy computer-aided detection schemes that will be more accurate than current-generation systems that rely on CT attenuation values.

CT approaches IVUS in plaque detection
Monday, November 28 | 3:30 p.m.-3:40 p.m. | SSE03-04 | Room S502ABA study comparing CT to intravascular ultrasound (IVUS) for plaque detection found that CT isn't quite ready to take on ultrasound -- but it's not far off, the authors concluded.

Extent of perfusion defects predicts PE outcomes
Monday, November 28 | 3:30 p.m.-3:40 p.m. | SSE05-04 | Room S404CDQuantifying perfusion defects at dual-energy CT helps identify pulmonary embolism (PE) patients at risk of adverse outcomes and should be part of their risk assessment, say investigators from the University of Munich.

CT equivalent to MRI in evaluating ventricular size, function
Monday, November 28 | 3:10 p.m.-3:20 p.m. | SSE03-02 | Room S502ABVentricular size and function are important for diagnosing and managing patients with several conditions. Fortunately, dual-source CT has caught up to the reference standard, MRI, for the task, say researchers from the Medical University of South Carolina.

Cryoablation safe, effective in treating soft-tissue sarcoma
By Amerigo Allegretto
Percutaneous cryoablation is safe and effective for patients with recurrent or metastatic soft-tissue sarcoma after earlier treatments.
August 1, 2024
(A) Axial noncontrast CT chest image shows soft tissue mass in the anterior chest wall (arrow). The lesion was treated by percutaneous cryoablation. (B) Intraprocedural axial CT image obtained during cryoablation. The pink outline represents the target lesion and the blue outline represents ice ball. Based on review, the procedure was classified as achieving adequate ablation. (C) Axial contrast-enhanced CT chest image, obtained three months after ablation (patient’s first follow-up exam), shows involution of the target lesion without evidence of residue.
