A workstation introduced March 11 at the American College of Cardiology conference processes MR cardiac data with such detail that the information rivals what can be obtained from conventional modalities, according to developer Toshiba America Medical Systems.
A workstation introduced March 11 at the American College of Cardiology conference processes MR cardiac data with such detail that the information rivals what can be obtained from conventional modalities, according to developer Toshiba America Medical Systems.
The workstation, FDA clearance for which is imminent, processes MR angiographic data acquired with the company's newly released 1.5T Vantage ZGV, using software that does not require contrast-enhanced data. Specialized algorithms correct for motion artifacts in real-time.
"We are on the verge of having a complete cardiac panel," said Bob Giegerich, director of the MR business unit at Toshiba America Medical Systems. "With this, MR will replace everything - nuclear medicine, ultrasound, and cardiac cath."
Gadolinium-based studies performed on the Vantage ZGV and processed on the new workstation pick up scars in the myocardium so small they may escape detection with thallium studies using conventional gamma cameras, he said. Delayed enhancement data, also obtained with contrast, might help identify patients who will benefit from revascularization following myocardial infarction.
Giegerich touts the Vantage ZGV, which began routine shipping only in the last several weeks, as a premium-performance high-field system, delivering performance in some cases comparable to that of 3T scanners.
The new system and development efforts aimed at enhancing its performance will be profiled March 20 in the next issue of DI SCAN.
Study Raises Doubt About AI Sensitivity for Smaller and Multiple Findings on Chest X-Rays
September 29th 2023In a multicenter study examining four commercially available artificial intelligence (AI) software products for chest X-rays in over 2,000 patients, researchers found sensitivity rates ranging between 33 to 61 percent for vague airspace disease and 9 to 94 percent for small pneumothorax and pleural effusion.
Seven Takeaways from New Analysis of Malpractice Cases Involving Interventional Radiologists
September 27th 2023Thirty-five percent of the interventional radiology malpractice cases involved vascular procedures and 26 percent of overall malpractice cases that went to trial resulted in plaintiff judgments with the average award being over $2 million.
