(Booth 6654) Look for Wuxi, China-based Chison Medical Imaging to launch two new color Doppler ultrasound systems, the iVis 60 Expert console system and the Q8 portable unit, at this year's RSNA show.

The systems offer new imaging technologies such as double-phasing digital beam formation (DPDBF), speckle reconstruction algorithm (SRA), and compound imaging. Chison's extended cardiac software provides tissue Doppler, free M-mode, and other functions that are of particular interest to cardiac imagers.

The scanners have been cleared by the U.S. Food and Drug Administration and are currently available worldwide.

Ultrasound falls short for detecting endometrial cancer in Black women

February 21, 2025

1Each lung has been split into three parts. Each area has been given a score between 0 and 3. Score values are shown in Ultrasonograms to match 4 different patterns. During a longitudinal scan with a high-resolution linear probe, pictures of patterns were taken. The scores are as follows: 0 means A pattern, 1 means B pattern, 2 means severe B pattern, and 3 means extended consolidation.

LI-RADS ultrasound surveillance version 2024 improves HCC detection

By Amerigo Allegretto

The 2024 version of the LI-RADS Ultrasound Surveillance system improves detection of hepatocellular carcinoma (HCC) over earlier iterations.

(A,B) Images from an initial ultrasound examination showed no identifiable lesions and received a consensus ultrasound category of US-1. Nearly the entire liver is visualized, with minimal shadowing (“s”, A and B), and the examination received consensus result of VIS-A. The AFP level was 7.1 ng/mL on assessment six months before the ultrasound, 9.1 ng/mL on assessment three months before examination, and 14.2 ng/mL on assessment on exam day. The AFP result was thus assessed as positive based on a progressive increase on two consecutive tests. The atient was considered to have negative surveillance result according to LI-RADS Ultrasound Surveillance v2017, but positive surveillance result according to LI-RADS Ultrasound Surveillance v2024. (C-D) Axial arterial-phase (C) and portal-venous phase (D) T1-weighted images from subsequent gadoxetic acid-enhanced MRI show a 2-cm arterial-phase hyperenhancing observation (arrow, C) with portal-venous washout (arrow, D) in segment 7. This observation was classified on MRI as LR-5, thus meeting the present study’s reference standard for diagnosis of HCC. The mass is located in the periphery of the liver, an anatomic area where ultrasound visualization can be challenging due to shadowing.

CEUS resolves indeterminate CT, MRI liver observations

By Amerigo Allegretto

Contrast-enhanced ultrasound (CEUS) can resolve some high-risk indeterminate liver observations initially seen on CT or MRI.

January 21, 2025

Images depict a 49-year-old female participant with cryptogenic cirrhosis who presented with a 3.2-cm liver lesion. This biopsy-confirmed hepatocellular carcinoma (HCC) with an initial categorization of Liver Imaging Reporting and Data System (LI-RADS) category LR-4 (probably HCC) at CT was upgraded to LR-5 (definitely HCC) at contrast-enhanced ultrasound (CEUS). (A) Precontrast CT images in the liver show vague hypoattenuation in the medial left hepatic lobe (arrows). (B) Arterial phase images demonstrate no definite arterial phase hyperenhancement (arrows). (C) Washout and an enhancing capsule (arrows) on a late-phase image resulted in an LR-4 categorization. (D) B-mode ultrasound shows a round hypoechoic nodule (arrows). (E) An early-phase CEUS image shows clear arterial-phase hyperenhancement (arrows); (F) No washout at one minute (arrows), and (G) late, mild washout at four minutes (arrows) resulted in a CEUS LR-5 categorization.

Ultrasound ablation is effective for treating hyperparathyroidism

By Amerigo Allegretto

Ultrasound-guided thermal ablation techniques are safe and effective in treating patients with secondary hyperparathyroidism.

January 7, 2025

Ultrasound images depict a 63-year-old man who underwent radiofrequency ablation (RFA) for the treatment of secondary hyperparathyroidism. (A–D) 2D images show four hyperplastic parathyroid glands on the right and left sides (marked with crosshairs). The numbers near the crosshairs represent the number of measured trails. (E) Ultrasound-guided infusion of isolation fluid (arrowheads) around the hyperplastic parathyroid gland to protect vital organs such as the trachea (Tr), carotid arteries (CA), and recurrent laryngeal nerve pathway area (arrow). F) Ultrasound-guided RFA of the hyperplastic parathyroid gland. (G) Immediate postoperative contrast-enhanced ultrasound shows no contrast enhancement in the ablation area. The ablation procedures for the other three parathyroid glands were the same as those described above. Image courtesy of the RSNA,
